¶ 1 The dispositive issue presented on review is whether the claimant met the statutory definition of a “physically impaired person” at the time of the claimant’s second on-the-job injury for purposes of determining eligibility for Multiple Injury Trust Fund (Fund) benefits. Subsumed in this determination is whether a duly-executed settlement agreement — memorialized on a form prescribed by the Workers’ Compensation Court (WCC) — constitutes an adjudication of the claimant’s disabilities. This Court answers both questions in the affirmative.

I. BACKGROUND AND PROCEDURAL HISTORY

¶2 On April 29, 1991, Tommy Garrett (Claimant) sustained a compensable on-the-job injury while working for the Oklahoma Department of Transportation (ODOT). Claimant stated that he was driving a road grader when a semi-truck, traveling approximately sixty-miles-per-hour, ran off the road and struck the left side of the grader.

¶3 Claimant was diagnosed with L5-S1 bilateral disc herniation with irritation of the SI nerve root. Claimant was treated but ultimately required surgery to his back. The operative report described the surgery as a “[bjilateral decompressive laminectomy and bilateral right and left sided laminectomy with discectomy L5-S1 interspace with bilateral decompression SI nerve roots.”1

¶4 Claimant subsequently filed a claim against ODOT in the WCC.2 On August 13, 1992,3 Claimant, ODOT and ODOT’s insurance carrier settled Claimant’s claim and memorialized that settlement in a WCC-prescribed form titled: Joint Petition. The Joint Petition disclosed injury to Claimant’s “NECK, BACK AND ARM AND ALL *171OTHER INJURIES BOTH KNOWN AND UNKNOWN.” As a result of Claimant’s injuries, “claimant was temporarily totally disabled from 4/29/91 to 7/7/92 ... for which claimant received $15,293.00, from the respondent or insurance carrier.” The Joint Petition further stated that, “[claimant further alleges that in addition to said temporary total disability, claimant has sustained certain permanent disabilities which are com-pensable under the Workers’ Compensation Act of the State of Oklahoma, which last allegation is by respondent or insurance carrier expressly denied.” The Joint Petition also indicated Claimant’s acceptance of a $100.00 settlement payment as “compensation for temporary disability, permanent disability, permanent disfigurement, ... and vocational rehabilitation or loss of wage earning capacity which claimant now has or may hereafter have as a result of said injury” against “respondent and insurance carrier.” (emphasis provided). That same day, the WCC, after reviewing the evidence, the stipulation of the parties, the files and record, approved the Joint Petition. Neither party appealed.

¶ 5 Ovér fifteen years later, on March 22, 2007, Claimant suffered another compensa-ble on-the-job injury while working for Rodger Jeffcoats, Inc. (Employer). Claimant filed a claim against Employer in the WCC on May 15, 2008. As a result of this injury, the tribunal ordered Employer or its insurance carrier to pay Claimant fifty-two weeks of temporary total disability (TTD).4 Claimant, Employer and Employer’s insurance carrier entered into a Compromise Settlement on May 24, 2012, another WCC-prescribed form.5 That agreement awarded Claimant $125,000 for the permanent, partial disability (PPD) and impairment ratings to the following body parts:- 40% right knee, 40% left knee and 42% back. The WCC approved the parties’ settlement that same day. Neither party appealed.

¶ 6 On October 31, 2012, Claimant filed a Form 3F seeking benefits from the Fund.6 This form recited Claimant’s impairment ratings from the latest on-the-job injury as 40% right leg, 40% left leg and 42% back.7 Claimant also referenced the 1991 on-the-job injuries to his neck, back and arm.8 The Fund denied liability and jurisdiction alleging that Claimant was not a “previously impaired person” as defined by Okla.’ Stat. tit. 85, § 171 (Supp. II 2005).9 Specifically, Fund alleged that there was no disability or percentage therefrom adjudged and determined prior to Claimant’s latest on-the-job injury. '

¶ 7 The tribunal appointed an independent medical examiner (IME) to evaluate Claimant and “determine if claimant is permanently and totally disabled due to the combination of [Claimant’s] injuries.”10 After the examination, the IME concluded .that Claimant’s 1991 prior claim

was subrogated through third party insurance; however, he was awarded $15,293.00 for temporary disability for 62 weeks and ... $100.00 ... for permanent disability. [I]f it is determined by the Court that the injuries to his back are combinable and using ■ the fact that he was temporarily totally disabled for 62 weeks, this would *172convert to approximately 12% impairment to the body as a whole.11

The TME also opined that Claimant’s injuries were synergistic and assessed a “material increase of 10% over and above the numerical sum of these injuries, giving him a total of 116.5% impairment to the body as a whole.” Combining those findings with Claimant’s age, education and work experience, the IME found Claimant to be permanently totally disabled and “unable to return to the workforce.”12

¶ 8 The tribunal found Claimant to be a. “previously physically impaired person” at the time of Claimant’s latest, compensable on-the-job, injury and ordered Fund to pay Claimant $289.00 per week for fifteen years.13 Fund appealed to the en banc panel of the tribunal. Upon reexamination, the panel fpund the tribunal’s order contrary to law and against the clear weight of the evidence.14 Based on its findings, the panel remanded the matter “for a redeterminátion of whether Claimant was a previously impaired person and the amount of disability and then for determination of whether claimant is.permanently, totally disabled, due to a combination of injuries.”15

■ ¶ 9 On remand, the tribunal again determined that both of Claimant’s compensable on-the-job injuries resulted in permanent impairments. The tribunal adjudged Claimant permanently totally disabled as a result of those injuries and the “material increase resulting. therefrom.”16 Although the tribunal stated that it “no longer [was] allowed to award [a] specific percent of disability,” the tribunal applied Okla. Stat. tit. 85, § 329(J) and held that the IME opinion “shall be followed unless there is clear and convincing evidence to the contrary.” It found none. Fund appealed. ■

¶ 10 The Court of Civil Appeals reversed. Relying on Ball v. Multiple Injury Trust Fund, 2015 OK 64, 360 P.3d 499, COCA held that the tribunal’s “finding of preexisting permanent disability where there was no such prior finding ... is in essence a Crumby17 finding.”18 As such, Claimant failed to establish that he was a physically impaired person. Claimant appealed. This Court granted certiorari review.

¶ 11 On certiorari, Claimant urges that COCA’s vacation of the tribunal’s order awarding Claimant permanent total disability (PTD) benefits against Fund was error. Relying on the rationale in Multiple Injury Trust Fund v. Sugg, 2015 OK 78, 362 P.3d 222, Claimant urges that the 1992 Joint Petition constitutes an adjudication of Claimant’s disabilities and renders Claimant a “physically impaired person” as contemplated by section 171 at the time of Claimant’s 2007 on-the-job injuries. Fund, on the other hand, disagrees and avers that Ball is controlling.

¶ 12 At the outset, this Court distinguishes Ball v. Multiple Injury Trust Fund, 2015 OK 64, 360 P,3d 499 from the issues and facts presented here. In Ball, this Court held that assigning a Crumby finding of preexisting disability to an unrelated injury in the absence of a prior adjudication, simultaneously with an adjudication of a subsequent, compensable on-the-job injury to render a worker a “physically impaired person” was prohibited, (emphasis added). The crucial element missing in Ball was that the *173worker lacked a prior adjudicated injury. Ball, 2015 OK 64 ¶¶ 1, 13, 360 P,3d at 504-05. Por reasons discussed in Part III, infra, this Court finds Ball inapplicable.'

II. STANDARD OF REVIEW

¶ 13 The overarching issue pressed on appeal is whether Claimant constituted a “physically impaired person” at the time of Claimant’s subsequent work-related injury on March 22, 2007. Resolution of this issue hinges upon whether the 1992 Joint Petition constituted a prior adjudication of Claimant’s disabilities as contemplated by section 171. Okla. Stat. tit. 85, § 171 (Supp. II 2005). Whether a worker was correctly adjudged a “physically impaired "person” within the meaning of the Act is a jurisdictional question of law this Court reviews de novo. Special Indem. Fund v. Choate, 1993 OK 15 ¶ 12, 847 P.2d 796, 801.

III. ANALYSIS

A. Joint Petition

¶ 14 This Court first determines that the 1992 Joint Petition is an adjudication of Claimant’s injuries and resulting disabilities. The WCC is a creature of statute. Strong v. Laubach, 2004 OK 21, 110, 89 P.3d 1066, 1070. This statutory creation not only provided a scheme for compensation of injured workers’ claims, but also a means for settling disputes, absent a full adversary hearing. See Okla. Stat. tit. 85, §§ 1-203(1981 & Supp. II 1990); See also In re Hyde, 2011 OK 31 ¶ 10, 255 P.3d 411, 414. The statutes and rules governing the parties’ 1992 Joint Petition, here, are those in effect at the time of Claimant’s first injury. Bertrand v. Laura Dester Ctr., 2013 OK 18 ¶ 14, 300 P.3d 1188, 1192. Claimant’s first .compensable injury was April 29, 1991. Accordingly, the 1981 version and 1990 supplement of Title 85, controls.

¶ 15 Rule 11 provides in pertinent part:

The court shall .prepare and adopt such forms for use in matters before the court as it may. deem necessary or advisable. Whenever the court forms are prescribed and are applicable, they shall be used. ... The following forms have been adopted by the court:

[[Image here]]

Compromise Settlement

[[Image here]]

Joint Petition

Okla. Stat. tit. 85, ch. 4, Rule 11 (Supp,. II 1991). ' ,

Section 1.2(E) provides in pertinent part:

All rules and regulations, upon adoption, shall be submitted to the Supreme Court, which shall either approve or disapprove them within thirty (30) days. All rules and. regulations, upon approval by the Supreme Court, shall be published and be made available to the public and, if not inconsistent with the law, shall be binding in the administration of the Workers’ Compensation Act.

Okla. Stat. tit. 85, § 1.2(E) (1981).

And, Section 26 provides in pertinent part:

If the employer and the injured employee shall reach a final agreement as to the facts with relation to an injury, and thé resulting disability for which compensation is .claimed under the Workers’ Compensation Act, a memorandum of such agreement, in form as prescribed by the Administrator, signed by both the employer and employee, and approved by the Court shall be filed by the employer with the Administrator. In' the absence of fraud this agreement shall be deemed binding upon the parties thereto. Such agreement shall be approved by the Court only when the terms conform to the provisions of the Workers’ Compensation Act.

¶ 16 At the time of Claimant’s and ODOT’s agreement to settle, the WCC prescribed only two methods for resolving compensable claims subject to this Court’s approval: Compromise Settlement and Joint Petition. See Okla. Stat. tit. 85, ch. 4, Rulé 11 (Supp. II 1991); Okla. Stat. tit. 85, § 1.2(E) (1981). In accordance with the Act, Claimant and ODOT elected to settle by Joint Petition. That agreement was signed by the parties, identified Claimant’s injuries, and awarded compensation for the resulting temporary and permanent disabilities. This Court notes that the Joint Petition indicates ODOT paid Claimant TTD. benefits and a $100 PPD *174award, acknowledging some degree of permanence to Claimant’s work-related injuries.

¶ 17 On August 13, 1992, the WCC approved the Joint Petition after determining that the agreement conformed to the provisions of the Act. See § 26. Upon expiration of the time for appeal, the Joint Petition became a final adjudication of Claimant’s injures. See also Okla. Power Co. v. State Indus. Comm’n, 1932 OK 171, ¶ 5, 166 Okla. 121, 9 P.2d 443, 444 (This Court held that the approval of a joint petition by the State Industrial Commission was a final adjudication and will not be subject to a collateral attack after the appeal time has expired.). No controlling distinction exists between adjudications memorialized by a final order and a judge-approved joint petition. Roberts v. Tway Constr. Co., 1974 OK 128, ¶18, 528 P.2d 1389, 1392. Simply put, an “adjudication” is any judicial action, See Depuy v. Hoeme, 1989 OK 42, ¶¶8-9, 775 P.2d 1339, 1342-43, including actions memorialized in a joint petition. Black, Sivalls & Bryson v. Bass, 1973 OK 9, ¶8, 506 P.2d 902, 904. Accordingly, this Court holds that the 1992 Joint Petition constitutes a “previous adjudication!;] of disability adjudged and determined by the Workers’ Compensation Court.” Okla. Stat. tit. 85, § 171 (Supp. II 2005). The mere fact that the WCC-prescribed form failed to include the exact degree of impairment is irrelevant as to whether there was a final adjudication.

B. Physically Impaired Persons

¶ 18 Fund advances a strained interpretation of section 171. Specifically, Fund challenges the 1992 adjudication of Claimant’s disabilities as the Joint Petition lacks an impairment rating. Fund, however, is mistaken.

¶ 19 The Fund’s liability for PTD benefits is statutorily limited to “physically impaired persons” at the time a claimant seeks benefits from the Fund. See Special Indem. Fund v. Carson, 1993 OK 64, ¶ 7, 852 P.2d 157, 158. At the time of Claimant’s 2007 injuries and 3F claim, the statute in effect in pertinent part read:

For purposes of Sections 171 through 176 of this title, the term “physically impaired person” means a person who as a result of accident, disease, birth, military action, or any other cause, has suffered [the statute enumerates losses] ... or any previous adjudications of disability adjudged and determined by the Workers’ Compensation Court or any disability resulting from separately adjudicated injuries.

Okla. Stat. tit. 85, § 171 (Supp. II 2005) (emphasis added).

¶ 20 From a plain reading of the statute, section 171 merely requires Claimant, here, to have a prior adjudicated disability. Nothing in the text of Section 171, however, requires a quantifiable percentage of impairment to accompany the prior adjudicated disability as Fund alleges. In construing statutes, “[t]he general rule is that nothing may be read into a statute which is not within the manifest intention of the legislature as gathered from the act itself ....” Huffman v. Oklahoma Coca-Cola Bottling Co., 1955 OK 76, ¶ 18, 281 P.2d 436, 440 (quoting 50 Am. Jur., Statutes, § 244). At the time of Claimant’s subsequent compensable injury on March 22, 2007, Claimant had satisfied the statutory definition of a “physically impaired person” by virtue of the 1992 adjudication.

C. Permanent Total Disability Claims Against the Fund

¶ 21 Before Claimant, here, can collect full compensation from the Multiple Injury Trust Fund, Claimant’s disabilities must render Claimant permanently and totally disabled. Section 172(B)(3) prescribes the manner in which compensation benefits are to be determined where a “physically impaired person” has received a subsequent work-related injury on or after November 1, 2005. The pertinent portion applicable to this case provides:

if such combined disabilities constitute permanent total disability, as defined in Section 3 of this title, then the employee shall receive full compensation as provided by law for the disability resulting directly and specifically from the subsequent injury. In addition, the employee shall receive full compensation for permanent total disability if the combination of injuries renders *175the employee permanently and totally disabled, as above defined, all of which shall be computed upon the schedule and provisions of the Workers’ Compensation Act. The employer shall be liable only for the degree of percent of disability which would have resulted from the subsequent injury if there had been no preexisting impairment. In permanent total disability cases the remainder of the compensation shall be paid out of the Multiple Injury Trust Fund and may be paid in periodic payments, as set forth in Section 22 of this title. The compensation rate for permanent total disability awai’ds from the Multiple Injury Trust Fund shall be the compensation rate for peimanent partial disability paid by the employer in the last combinable compensa-ble injury. Peimanent total disability awards from the Multiple Injury Trust Fund shall be payable for a period of fifteen (15) years or until the employee reaches sixty-five (65) years of age, whichever period is the longer. Permanent total disability awards from the Multiple Injury Trust Fund shall accrue from the file date of the court order finding the claimant to be permanently and totally disabled.

Okla. Stat. tit. 85, § 172 (B)(3) (Supp. II 2005).

¶ 22 As a practical matter, a Crumby finding of a claimant’s preexisting disability is a necessary component in determining the claimant’s present capacity for work. In fact, it is an indispensable factor in supplying the extent of a “claimant’s prior (unrelated) disability and the compensable injury’s impact ...Multiple Injury Trust Fund v. Sugg, 2015 OK 78, ¶ 8, 362 P.3d 222, 226.

¶ 23 In affixing the liability of the Multiple Injury Trust Fund, this Court most recently noted that,

[u]nder § 172(B)(3), with regard to the Fund’s liability for subsequent injuries occurring after November 1, 2005, the dis-positive issue is whether an employee is permanently and totally disabled. Notably, ... the statute does not limit the Fund’s liability to the disability resulting from the subsequent injury as if there had been no preexisting impairment. ... [T]his Court has said that a Crumby finding is a rated assessment of the effect,, if any, upon the claimant’s alleged capacity status from the interplay of his compensable harm with the unrelated pre-existing conditions. Effect refers to that component of the claimant’s total disability from pre-existing impairments which may contribute to his current condition and which may have an effect on his present capacity for work. Additionally, a Crumby finding supplies the extent of a claimant’s prior (unrelated) disability and the compensable injury’s impact, if any, on the claimant’s prior impairments. Thus, when the Claimant is being evaluated for permanent total disability; a Crumby finding of preexisting disability is relevant in determining his or her present capacity for work.

Id. (quotations omitted) (citations omitted) (emphasis added).

¶ 24 In effect, the statutory language implicitly requires a Crumby finding when the claimant by “accident, disease, birth, military action, or any other cause, has suffered” one of the losses enumerated in the statute or whose prior disabilities have been adjudged and determined by the WCC.19 Id.; See also Okla. Stat. tit. 85, § 171 (Supp. II 2005). Upon meeting the statutory requirements of sections 171 and 172, the Court’s sole prerogative then becomes whether the worker is permanently totally disabled.

¶ 25 The record, here, reveals that Claimant was engaged in gainful employment prior to Claimant’s latest on-the-job injuries in 2007. But, thereafter, the synergistic effects *176of Claimant’s multiple, adjudicated work-related injuries required a material increase over and above the numerical sum of Claimant’s preexisting injuries. The record also demonstrates that in' combining Claimant’s multiple work-related injuries with Claimant’s age, education and work experience, Claimant was unable to return to the workforce. Claimant is permanently and totally disabled; and, therefore, entitled to an award of PTD benefits from the Fund.

IV. CONCLUSION

¶ 26 As a matter of law, this Court holds that the 1992 Joint Petition constitutes a prior adjudication of Claimant’s disabilities. Therefore, this Court concludes that Claimant qualifies as a “physically impaired person” as contemplated by Okla. Stat. tit. 85, § 171 (Supp. II2005).

¶ 27 Today, this Court reiterates its holding in Multiple Injury Trust Fund v. Sugg, 2015 OK 78, 362 P.3d 222, that “[o]nce an employee has established that he or she is a physically impaired person, .,. for subsequent injuries occurring after November 1, 2005, the dispositive issue is whether the employee is permanently and totally disabled.” Okla. Stat. tit. 85, § 172(B)(3) (Supp. II 2005). At this point, “[a] Crumby finding of preexisting disability may be combined with other impairments in, determining whether the employee is permanently totally disabled and entitled to an award against the Fund.” Multiple Injury Trust Fund v. Sugg, 2015 OK 78, ¶ 11, 362 P.3d 222, 226. Based on the foregoing,' this Court concludes that Claimant is permanently and totally disabled; and, therefore, entitled to an award against the Fund.

’ CERTIORARI PREVIOUSLY GRANTED; COURT OF CIVIL APPEALS OPINION VACATED; WORKERS’ COMPENSATION COURT ORDER AFFIRMED.

with whom Winchester, J., joins, dissenting:

¶ 1 The question presented by this case is not whether a workers’ compensation judge’s approval of a joint petition settlement can constitute an '‘adjudication” of certain facts. We long ago held that it could. The question is whether the judge’s approval of this joint petition settlement was an “adjudication” of the specific fact relevant to the outcome of this case: whether Tommy Garrett was permanently disabled as a result of his 1991 on-the-job injury.

¶ 2 The trial court found that Garrett had “sustained two compensable job injuries in 1991 and 2007” and that “[bjoth were permanent impairments and both were- admitted with benefits paid.”* That conclusion, however, is not supported by the actual text of the 1992 joint petition settlement, which explicitly states that Garrett’s employer disputed Garrett was permanently disabled as a result of his 1991 injury,2 and contains no finding to the contrary from the approving judge. The Court of Civil Appeals was thus correct to reverse the trial court for its erroneous conclusion,

¶ 3 The majority, however, affirms the trial court by placing more weight on our precedents than they can .bear, seemingly reading our cases as creating a rule whereby approval of a joint petition settlement constitutes a judicial determination in favor of the claimant of all fact questions, even those specifically left in dispute by the parties as part, of their agreement. But this legal fiction is neither required by our precedents nor authorized by the governing statute, which requires *177an actual adjudication of permanent disability. For these reasons, I respectfully dissent,

I.

A. Factual Background

¶ 4 In the spring of 2007, Tommy Garrett hurt his knee when he fell from a ladder while working as an air-conditioner repairman. About 'a year later, he hired an attorney and initiated a workers’ compensation claim against his employer by filing a “Form 3” with tiie Workers’ Compensation Court, indicating that he had suffered an injury to his left knee. That form asked Garrett whether he was “a" previously impaired person due to a prior workers’ compensation injury or obvious and apparent pre-existing disability,” because if so he would need to submit a different form (a “Form 3F”) and “may be entitled to benefits for combined disabilities.”3 Garrett answered “No,” and he and his attorney signed the form under the penalty of perjury, affirming that “all statemeiits made herein” were “true, correct and complete.”4

¶5 Over the. span of the next year and a half, Garrett’s attorney filed two amended Form 3’s, first to change the description of Garrett’s injury to include a claim of injury to his right knee and back,5 and then later to include a claim of injury to his back and right “leg” rather than just his knee.6 On neither of the amended forms did Garrett amend his answer to the question asking if he was a previously impaired person.

¶ 6 The case proceeded for the next several years as a straightforward, single-injury claim, with Garrett never claiming that he had suffered any prior permanent impairment.7 Finally, in May of 2012, Garrett and his employer entered into a compromise set-tiement, resolving all issues between the parties with respect to his 2Q07 injury,8

¶'7 It wasn’t until October, 2012, that Garrett filed a Form 3F, making the new claim that his 1991 injury had permanently impaired him and, that through a combination of that preexisting impairment and the 2007 injuries, he, was now permanently, totally disabled and incapable of gainful employment. The Form 3F asked Garrett to list the percentage of permanent disability he had incurred and the settlement award he had received for that permanent1 disability in 1991, but Garrett provided'no response.9

¶ 8 Because this claim against the Multiple Injury. Trust Fund turned on whether he was a “physically impaired person” at the time of his 2007 injury, which in turn depended on whether he had “any previous adjudications of disability adjudged and determined by the Workers’ Compensation Court,”10 Garrett’s ability to recover from the MITF hinged on his equating the 1992 joint petition with a “previous adjudieation[ ] of disability.” Garrett thus alleged — contrary to his prior statements — that the 1992 joint petition contained an award for permanent disabilities and that the court’s approval of the award constitutes the requisite “adjudication” of prior permanent impairment.

¶ 9 In the 1992 joint petition settlement, Garrett and his employer agreed that Garrett had suffered “neck, back and arm” injuries that caused him to be “temporarily totally disabled” and for which he had received $15,293.00 in TTD benefits.11 The settlement notes that Garrett “further alleges that in addition to said temporary total disability, [he] has sustained certain permanent disabilities which are compensable” and, that this “allegation is by respondent or insurance *178carrier expressly denied.”12 The parties agreed to settle all of Garrett’s claims for $100.00, which was a “full, final and complete settlement of all claims for statutory medical aid for rehabilitation procedures and for compensation, including compensation for temporary disability, permanent disability, permanent disfigurement, the benefits of physical and vocational rehabilitation or loss of wage earning capacity which claimant now has or may hereafter have as a result of said injury.”13

¶ 10 The joint petition settlement includes an order from the Workers’ Compensation Comí; approving the settlement,14 which states that the court, “having reviewed the evidence, the files and records in said cause and being fully advised in the premises, finds that the above Joint Petition, incorporated herein and made a part hereof by reference, should be and is hereby approved.”15 The order directs that the 3% Special Indemnity Fund Tax and a $20 attorney fee be paid out of the settlement proceeds. The order makes no findings with respect to Garrett’s claim of permanent disability; it simply approves the joint petition as is, preserving the dispute as to Garrett’s claim of permanent disability.

B. Procedural History

¶ 11 After Garrett made his claim against the MITF, the Workers’ Compensation Court appointed an independent medical examiner to evaluate Garrett. In that examiner’s report, he discussed Garrett’s 1991 injury and noted that Garrett was “awarded $15,293.00 for temporary disability for 62 weeks and he was given a bonus of $100.00.”16 “While this was not a truly adjudicated case,” went on the examiner, “if it is determined by the Court that the injuries to his back are combinable ... this would con*179vert to approximately 12% impairment to the body as a whole.”17 The examiner concluded that Garrett’s 1991 and 2007 injuries were “synergistic” and that Garrett was now suffering from 116.5% impairment of his whole body, and was thus permanently, totally disabled.18 Based upon this report, the Workers’ Compensation Court found that Garrett was a “previously physically impaired person” at the time of his 2007 injury, that he was now permanently, totally disabled as a result of the combined effects of his 1991 and 2007 injuries, and that he was entitled to permanent-total-disability benefits from the MITF in the amount of $289 per week for the next fifteen years.19

¶ 12 The MITF appealed to a panel of the Workers’ Compensation Court, arguing that the trial court’s decision was improper because there was no prior adjudication of disability by the trial judge that would make the MITF liable for Garrett’s award. The panel reversed the trial judge’s decision, finding that it was “contrary to law AND against the clear weight of the evidence.”20 The three-judge panel thus remanded the ease to the trial judge for a “redetermination of whether claimant was a previously impaired person and the amount of that disability and then for determination of whether claimant is permanently, totally disabled due to a combination of injuries.”21

¶ IS On remand, the trial judge held that Garrett had “sustained two compensable job injuries in 1991 and 2007” and that “[bjoth were permanent impairments and both were admitted with benefits paid.”22 The trial judge further held that “the combination of the two injuries make claimant permanently totally disabled” and reinstated the award of $289 per week for fifteen years.23

¶ 14 The MITF immediately appealed this decision, and we assigned the ease to the Court of Civil Appeals. That Court reversed and remanded the decision, finding that the 1992 joint petition did not “adjudge and determine” that Garrett had suffered permanent disability, and thus the trial court’s finding was essentially a Crumby finding such that' Garrett was not a previously physically impaired person able to pursue recovery from the MITF.

¶ 15 Garrett petitioned this Court for cer-tiorari, and we agreed to hear his ease.

II.

¶ 16 When the Legislature reinstated the Multiple Injury Trust Fund, it strictly limited the Fund’s liability to instances where a claimant was a “physically impaired person” at the time they suffered their latest on-the-job injury and is now permanently, totally disábled as a result of the latest injury.24 To be a “physically impaired person,” the claimant must meet one of two criteria, only one of which is relevant here: that the claimant has a “previous adjudication of disability adjudged and determined by the Workers’ Compensation Court.”25 We have held before that being a “physically impaired person” is in fact a jurisdictional element, meaning that no court can enter a judgment against the MITF unless this statutory prerequisite is met.26 The command from the Legislature is therefore abundantly clear: the Workers’ Compensation Court has no jurisdiction to enter an award against the MITF unless the Workers’ Compensation Court has previously “adjudged and determined” that the claimant *180has a permanent disability.27

¶ 17 The inquiry as to whether this statutory prerequisite has been satisfied must therefore begin with an examination of what the Legislature meant when it said “previous adjudication of disability adjudged and determined by the Workers’ Compensation Court.” Those terns are not statutorily defined, so I begin with the plain meaning of those words, as a legislator casting a vote in favor of the statutory language would have understood them. The plain meaning of “adjudicate” is “to hear or try and determine, as a court; to settle by judicial decree; to adjudge[.]”28 To “adjudge,” meanwhile, is “to determine in the exercise of judicial power; to decide or determine judicially,”29 while to “determine” is to “settle a question or controversy about; to decide by authoritative or judicial sentence.”30

¶ 18 Given the meaning, of these statutory terms, the Workers’ Compensation, Court’s approval of the 1992 joint petition settlement cannot be fairly read as having “adjudged and determined” that Garrett had suffered a permanent disability. The joint petition explicitly states that it leaves unresolved the question of whether Garrett had suffered a permanent impairment, and the court order approving the settlement is silent on the matter. Thus, as a matter of fact, the Workers’" Compensation Court adjudged and determined nothing with respect to whether Garrett had been permanently impaired.31 Given that no actual adjudication of permanent impairment occurred, § 171 renders the Workers’ Compensation Court without jurisdiction to enter an award against the MITF. In my view, this should be the end of . the matter.

¶ 19 I recognize," however, that we do- not come to this issue with a blank slate. But even putting aside the plain meaning of the statute, while we have previously held that a judge’s approval of a joint petition settlement sometimes' includes an adjudication and determination of the existence of underlying facts,32 today’s decision goes much further, creating a legal fiction whereby all allegations made by a claimant are deemed “adjudged- and determined” in his favor even when the order approving the joint petition plainly makes no such adjudication. None of our prior decisions mandate this result.

¶ 20 First, the cases relied on by the majority fall short of establishing any per se rule that an approved joint petition constitutes an adjudication of disability. The majority cites 'Oklahoma Power Co. v. State Industrial Commission33 as holding “that the approval of a joint petition by the State Industrial Commission was a final adjudication and will not be subject to collateral attack after the appeal time has expired.”34 That’s true; Oklahoma Power Co. does explain that judicial approval of a joint petition is imbued with the same finality as other judgments, but that case does not say that approval of a joint petition is ipso facto an adjudication of disability. Indeed, at most, that- case states that judicial approval of a joint petition settlement — like other settlement agreements— *181is an adjudication that the parties were competent to enter into such an agreement and, thus, that the agreement may not be challenged later on the basis of incapacity.35

¶ 21 And while Roberts v. Tway Construction Co36 does say that the Court could “perceive no controlling distinction” between a final order and a judge-approved joint petition,37 read in context, Roberts merely held that:

We perceive no controlling distinction between a final order which awarded compensation for a single injury without any finding respecting other injuries, and a joint petition settlement approved by a trial judge after consideration of medical evidence concerning only one of multiple injuries resulting from the same accident?38

The issue in Roberts was whether a joint petition settled all injuries arising from the same accident or merely the injuries described in the petition.39 The Roberts Court-relying on the plain text of the joint petition-concluded that the settlement only covered the injury listed on the petition form.40 In support, the Court cited Oil Capitol Sheet Metal Works v. Robinson,41 where the Court held that awards by final order also only adjudicate the injury in front of them and not all injuries arising from the same accident, hence the language regarding a lack of “controlling distinction.”42 Like Oklahoma Power Co. above, this ease does not hold that an approved joint petition is indistinguishable from a disability award authorized by final order. Instead, and again like Oklahoma Power Co., Roberts stands for the proposition that a judge-approved joint petition is only an adjudication of the issues determined in the petition, which Roberts demonstrates are determined by the text of the petition itself.

¶ 22 Likewise, this Court in Depuy v. Hoeme43 did not attempt to define “adjudication,” much less to define it as “any judicial action” or, more importantly, as any determination related to disability.44 And while Black, Sivalls & Bryson v. Bass,45 (like Oklahoma Power Co. and Roberts above) held that an approved joint petition constitutes a judicial determination, it also held (again like Oklahoma Power Co. and Roberts) that such a determination is limited to only the facts upon which the petition settlement was based.46

¶23 Contrary to the majority’s reading, none of these cases purport to make a joint petition identical to a final order procured following a fully litigated dispute. While both can finally resolve a claim and while both can constitute a judicial determination of facts, only one is an adjudication of every issue in a workers’ compensation case: the final order. *182The most these cases indicate is that an approved joint petition could constitute an “adjudication of disability” if permanent disability is a fact established or a fact that forms the basis of the petition settlement.

¶ 24 Indeed, that is exactly the rule this Court has announced in other eases addressing this issue. In a series of cases in the 1960’s, this Court determined that:

[Wjhere there is a prior settlement on joint petition which discloses that claimant had substantial permanent disability to the body as a whole the disability has been adjudged and determined within the meaning of Section 171 ... .47

Each of those cases included evidence beyond the text of the joint petition that “disclosed” the existence of permanent disability. The most analogous of those cases is Special Indemnity Fund v. Simpson.48

¶25 In Simpson, the claimant had I two work-related injuries, one in 1958 the other in 1948,49 both of which were settled by joint petition. There, as here, the Fund challenged claimant’s qualifications as a “physically impaired person,” arguing that his prior jpint petition settlement was insufficient to constitute an adjudication of disability. This Court, in accepting the joint petition as an adjudication of disability, noted that claimant included in the record a doctor’s report from the earlier joint petition proceeding “show[ing] a permanent partial disability of 35 percent to the body as a whole” as a result of the 1948 injury.50 In fact, a review, of that record shows that there were multiple doctors’ reports included dating back to the earlier injury, each of which indicated that the claimant was permanently disabled. Therefore, the evidence in that case disclosed the existence of permanent disability such that the court had a factual basis upon which to consider the approval of that settlement as an adjudication of disability, despite the settlement’s language leaving the claim of disability in dispute.51 The actual existence of permanent disability was even more apparent when considering that the claimant in Simpson received almost $5,000 to settle his claims.52

¶ 26 This case lacks any such evidence. Garrett has included no doctor’s reports, no transcripts, nothing to establish that he was actually permanently disabled as a result of his first injury. Indeed, the evidence in this record all seems to point to the contrary. First, Garrett and his employer settled his claims in 1992 for essentially nuisance value, demonstrating that the parties placed little value on his claim of permanent disability. Then there are Garrett’s statements and attestations throughout the subsequent-injury proceeding disclaiming the existence of any preexisting disability. And finally, there is the 1992 joint petition itself, which again contains language that expressly contests the *183existence of any such disability. This record does not come close to demonstrating that the 1992 joint petition settled an established claim of permanent disability. Rather, it demonstrates that no one — not even Garrett — thought the Workers’ Compensation Court had “adjudged and determined” that he was permanently disabled as a result of his 1991 injury until the potential for recovery from the MITP became apparent. This cannot be what the Legislature hád in mind when it agreed to make the MITF liable to claimants “suffer[i'ng]” from “previous adjudications of disability adjudged and determined by the Workers’ Compensation Court.”53

III.

¶ 27 Because the 1992 joint petition did not constitute a “prior adjudication of disability,” the next question is whether the 1991 injury can form the basis of a contemporaneous adjudication of preexisting disability — a.k.a. a Crumby54 finding — and whether that Crumby finding can nonetheless qualify Garrett as a “physically impaired person.” Our opinion in Ball v. Multiple Injury Trust Fund says that it cannot.55

¶ 28 In Ball we held that under the 2005 version of 85 O.S. § 171, “[a] Crumby finding of preexisting disability made simultaneously •with an adjudication of an on-the-job injury may not be combined with that adjudicated injury to render the Claimant a physically impaired person.”56 We have previously held that the law in effect at the time of the claimant’s subsequent injury is the law that governs the claim against the MITP.57 When Garrett suffered his subsequent injury in 2007, the most recent version of 85 O.S. § 171 was the 2005 version-the very same law at issue in Ball. Therefore, the ,2005 version of § 171 and Ball ⅛ interpretation of it govern Garrett’s claim against the MITP such that the Workers’ Compensation Court could not divine a- preexisting disability from the 1991 injury in order to qualify Garrett as a “physically impaired person.” Ball makes clear that any such adjudication of permanent disability had to exist before the claim arising from, the most recent injury.58 The fact that the 1992 joint petition left permanent disability explicitly contested again forecloses its use in establishing jurisdiction over the MITP.
