In this interlocutory appeal in a medical malpractice action, defendants Richard S. Veyna, M.D., Michigan Head and Spine Institute (MHSI), and University Neurosurgical Associates, PC (UNA) 1 appeal by leave granted 2 the trial court's order *308 granting plaintiff's motion for reconsideration and denying defendants' motion for summary disposition. The trial court denied defendants' motion for summary disposition on the ground that defendants failed to comply with MCR 2.112(L)(2)(a) in challenging plaintiff's notice of intent (NOI) to file a claim. For the reasons set forth in this opinion, we affirm.

I. BACKGROUND

Plaintiff's medical malpractice claim stems from the treatment that she received at McLaren-Macomb Hospital 3 in July 2013, related to a fall that had occurred at her home. Plaintiff was admitted to McLaren-Macomb Hospital on approximately July 2, 2013, where she was treated by a neurosurgeon, Dr. Veyna, who was employed by MHSI. 4 Plaintiff alleged that defendants were negligent in treating her condition, principally by failing to timely order and perform an MRI of her brain and cervical spine on July 4, 2013, and July 5, 2013. As a result of the delay in ordering or performing a brain MRI, plaintiff alleges there was a delay in the diagnosis and treatment of her spinal condition, causing prolonged compression of the spine. Plaintiff further alleged that the surgical procedure that was performed on July 13, 2013, 5 did not provide any benefit and that defendants' 6 negligence in failing to appropriately and timely diagnose her cervical spine pathology and relieve the pressure on her spinal cord caused her permanent quadriparesis.

On June 30, 2015, plaintiff, as required pursuant to MCL 600.2912b, mailed her NOI to, among others, defendants Dr. Veyna and MHSI. Plaintiff sent her NOI to Dr. Veyna by United States mail to the following addresses:

Richard S. Veyna, M.D.

c/o Michigan Head and Spine Institute

1030 Harrington Blvd.

Suite 100

Mt. Clemens, MI 48043

Richard S. Veyna, M.D.

c/o McLaren Macomb

1000 Harrington Blvd.

Mt. Clemens, MI 48043

Plaintiff sent her NOI to MHSI by United States Mail to the following addresses:

Michigan Head and Spine Institute

1030 Harrington Blvd.

Suite 100

Mt. Clemens, MI 48043

Michigan Head and Spine Institute, PLLC

Resident Agent: Harold D. Portnoy

44555 Woodward Avenue

Suite 506

Pontiac, MI 48341

MHSI, P.L.L.C.

Resident Agent: Harold D. Portnoy

Suite 506

Pontiac, MI 48341

*309 The two NOIs that were sent to the 44555 Woodward address were returned as undeliverable, but none of the other NOIs was returned.

On December 9, 2015, plaintiff filed her complaint against defendants alleging medical malpractice. Subsequently, on December 16, 2015, defendants' attorney, Scott Saurbier, contacted plaintiff's attorney, Matthew Turner, and requested a copy of the NOI that was sent, indicating that defendants had not received a copy. On December 28, 2015, Turner forwarded a copy of the NOI to Saurbier. Dr. Veyna averred that he never saw or received an NOI involving plaintiff until after being served with the complaint, that he was not an employee of McLaren-Macomb, and that neither MHSI nor McLaren-Macomb had ever indicated that an NOI had been delivered to them on his behalf. Additionally, Karin Green, the office administrator who receives all NOIs delivered to MHSI offices, averred that MHSI never received an NOI pertaining to plaintiff.

MHSI and UNA filed an answer on January 15, 2016, and Dr. Veyna filed an answer on February 9, 2016, in which defendants generally denied the allegations of negligence. Both answers raised as an affirmative defense that "[t]he claims are barred for failing to comply with MCL 600.2912b by not properly filing and providing sufficient Notice of Intent."

Thereafter, on March 4, 2016, Dr. Veyna and MHSI collectively moved for summary disposition pursuant to MCR 2.116(C)(8), arguing that plaintiff failed to give defendants the notice required by MCL 600.2912b(2) because plaintiff did not mail the NOIs to defendants' last known professional business addresses. Defendants argued that plaintiff mailed the NOIs to prior or nonexistent addresses, even though their correct addresses were reasonably ascertainable, and as a result, defendants did not receive the notice required under MCL 600.2912b to commence a medical malpractice action. Defendants contended that defendants' last known addresses could be determined by a Google search or, with respect to MHSI, by consulting the Michigan Department of Licensing and Regulatory Affairs (LARA) website.

In opposition to defendants' motion for summary disposition, plaintiff presented two arguments. First, plaintiff argued that defendants' motion was untimely under MCR 2.112(L)(2)(a), which strictly prescribes the time for challenging an NOI, and that defendants' motion must therefore be dismissed. Plaintiff asserted that under MCR 2.112(L)(2)(a), defendants were required to bring their challenge to the NOI by motion when they filed their answers but defendants failed to do so. Plaintiffs further maintained that there was not "good cause" as required by MCR 2.112(L)(2) that would permit the trial court to allow a later challenge to the NOI because defendants were aware of the addresses to which the NOIs were sent before they filed their answers. Second, plaintiff argued that she complied with the service requirements of MCL 600.2912b(2). Plaintiff asserted that she mailed the NOIs to defendants' last known professional business addresses as reasonably ascertained from the McLaren-Macomb website, Google searches, and the LARA website. Plaintiff also mailed an NOI to McLaren-Macomb, the only place where defendants rendered medical services to plaintiff. Plaintiff further argued that there was nothing to indicate that any one of the other business addresses for Dr. Veyna was his sole business address for receiving professional correspondence.

Defendants argued in reply that MCR 2.112(L)(2)(a) was inapplicable to their motion because defendants were not challenging *310 the contents of the NOI but instead were only challenging the lack of service of the NOI and plaintiff's failure to comply with the requirements of MCL 600.2912b(1). Defendants further argued that they had preserved their challenge by including it in their affirmative defenses filed with their answers, which put plaintiff on notice. Additionally, defendants argued that there was good cause for purposes of MCR 2.112(L)(2) to allow defendants' challenge because defendants' substantial rights were affected by not receiving the NOI, a medical malpractice action cannot be commenced against a defendant if an NOI is not provided to that defendant, and plaintiff had notice that defendants would assert this defense.

After a hearing on defendants' summary disposition motion, the trial court issued a written opinion and order granting the motion. The trial court noted that the parties had relied on matters beyond the pleadings and on that basis treated the motion as one brought under MCR 2.116(C)(10). The trial court concluded that summary disposition in defendants' favor was warranted because plaintiff had violated MCL 600.2912b(1) by completely failing to serve an NOI on defendants before filing the complaint even though their addresses were reasonably determinable.

Plaintiff moved for reconsideration, arguing, as pertinent to this appeal, that defendants' motion was untimely and that the trial court's initial ruling failed to address plaintiff's argument regarding the operation of MCR 2.112(L)(2)(a).

In a written opinion and order, the trial court granted plaintiff's motion for reconsideration and ruled that defendants' summary disposition motion was denied. The trial court concluded that defendants, by filing their answers and then challenging the NOI in their subsequent summary disposition motion, failed to comply with the clear language in MCR 2.112(L)(2)(a) that requires an NOI challenge to be made by a motion filed at the time the first response to the complaint is filed. Additionally, the trial court concluded that the court rule did not permit defendants to preserve a challenge to the NOI by merely raising it in the affirmative defenses in their answers because an answer is a pleading rather than a motion. The trial court further determined that there was no showing of good cause to allow defendants' untimely challenge.

Defendants sought leave to appeal the trial court's order, arguing that MCR 2.112(L)(2)(a), which applies in medical malpractice actions, was inapplicable in this case Specifically, defendants asserted that because the NOI was not properly served or actually received by defendants, plaintiff failed to comply with MCL 600.2912b and, therefore, a medical malpractice action was not commenced, rendering MCR 2.112(L)(2)(a) inapplicable.

This Court granted leave to appeal limited to the issues raised in the application and the supporting brief. Sanders v. McLaren-Macomb , unpublished order of the Court of Appeals, entered March 3, 2017 (Docket No. 336409). However, Judge GLEICHER indicated that she would have denied defendants' application because their argument lacked merit, stating that "the issue in this case is whether defendants were obligated to abide by the Court Rules, which clearly set forth when a challenge to an NOI must be made," and that "[d]efendants' belief that the case had never been properly filed does not excuse their flagrant disregard of ... MCR 2.112 [ (L)(2) ]." Sanders , unpub. order ( GLEICHER , J., dissenting), citing Saffian v. Simmons , 477 Mich. 8 , 727 N.W.2d 132 (2007).

*311 II. STANDARD OF REVIEW

We review de novo a trial court's decision on a motion for summary disposition. Saffian , 477 Mich. at 12 , 727 N.W.2d 132 . The trial court treated defendants' motion for summary disposition as one brought pursuant to MCR 2.116(C)(10), under which "[s]ummary disposition is appropriate if there is no genuine issue regarding any material fact and the moving party is entitled to judgment as a matter of law." Odom v. Wayne Co. , 482 Mich. 459 , 467, 760 N.W.2d 217 (2008) (quotation marks and citation omitted). In deciding a motion under MCR 2.116(C)(10), a court reviews "the pleadings, admissions, and other evidence submitted by the parties in the light most favorable to the nonmoving party." Id. at 466-467, 760 N.W.2d 217 (quotation marks and citation omitted).

This Court reviews for an abuse of discretion a trial court's ruling on a motion for reconsideration. In re Moukalled Estate , 269 Mich. App. 708 , 713, 714 N.W.2d 400 (2006). "[A]n abuse of discretion occurs only when the trial court's decision is outside the range of reasonable and principled outcomes." Saffian , 477 Mich. at 12 , 727 N.W.2d 132 . MCR 2.119(F)(3) requires the party moving for reconsideration to "demonstrate a palpable error by which the court and the parties have been misled and show that a different disposition of the motion must result from correction of the error." The trial court has "considerable discretion in granting reconsideration to correct mistakes, to preserve judicial economy, and to minimize costs to the parties." In re Moukalled Estate , 269 Mich. App. at 714 , 714 N.W.2d 400 (quotation marks and citation omitted).

Finally, we review de novo both questions of law and the interpretation of statutes and court rules. Haksluoto v. Mt. Clemens Regional Med. Ctr. , 500 Mich. 304 , 309-310, 901 N.W.2d 577 (2017).

III. ANALYSIS

MCL 600.2912b(1) provides, in relevant part, that "a person shall not commence an action alleging medical malpractice against a health professional or health facility unless the person has given the health professional or health facility written notice under this section not less than 182 days before the action is commenced." 7 The manner of providing the NOI to a potential defendant is set forth in MCL 600.2912b(2), which states as follows:

The notice of intent to file a claim required under subsection (1) shall be mailed to the last known professional business address or residential address of the health professional or health facility who is the subject of the claim. Proof of the mailing constitutes prima facie evidence of compliance with this section. If no last known professional business or residential address can reasonably be ascertained, notice may be mailed to the health facility where the care that is the basis for the claim was rendered.

These statutory provisions provide specific rules for initiating a medical malpractice action. As our Supreme Court has explained, "[a]lthough a civil action is generally commenced by filing a complaint, a medical malpractice action can only be commenced by filing a timely NOI and then filing a complaint and an affidavit of merit after the applicable notice period has expired, but before the period of limitations has expired."

*312 Tyra v. Organ Procurement Agency of Mich. , 498 Mich. 68 , 94, 869 N.W.2d 213 (2015). The statutory requirement that a plaintiff file a timely NOI is "a prerequisite condition to the commencement of a medical malpractice lawsuit," and "the failure to comply with the statutory requirement renders the complaint insufficient to commence the action." Driver v. Naini , 490 Mich. 239 , 257, 802 N.W.2d 311 (2011) (quotation marks and citation omitted).

MCR 2.112(L)(2) provides, in pertinent part, that

[i]n a medical malpractice action, unless the court allows a later challenge for good cause: (a) all challenges to a notice of intent to sue must be made by motion, filed pursuant to MCR 2.119, at the time the defendant files its first response to the complaint, whether by answer or motion [.]" [Emphasis added.] This provision was adopted by an amendment of the court rules that became effective on May 1, 2010. 485 Mich. cclxxv, cclxxvi (2010).

This Court "interpret[s] court rules using the same principles that govern the interpretation of statutes." Ligons v. Crittenton Hosp. , 490 Mich. 61 , 70, 803 N.W.2d 271 (2011). "[W]e look to the plain language of the court rule in order to ascertain its meaning and the intent of the rule must be determined from an examination of the court rule itself and its place within the structure of the Michigan Court Rules as a whole." Decker v. Trux R Us, Inc. , 307 Mich. App. 472 , 479, 861 N.W.2d 59 (2014) (quotation marks and citation omitted). "If the rule's language is plain and unambiguous, then judicial construction is not permitted and the rule must be applied as written." Id . (quotation marks and citation omitted).

First, MCR 2.112(L)(2)(a) states that the rule applies specifically to "all challenges to a notice of intent to sue," which, as previously noted, is a prerequisite condition to commencing a lawsuit for medical malpractice. Defendants argue that MCR 2.112(L)(2)(a) is inapplicable in this case because their challenge is based only on a claim that there was a lack of service and is not aimed at the content of the NOI. Thus, defendants argue, MCR 2.112(L)(2)(a) does not apply to their challenge based on a lack of service because the court rule only applies to challenges " to a notice of intent to sue." According to defendants, MCR 2.112(L)(2)(a) does not apply to all challenges involving the NOI requirements contained in MCL 600.2912b.

There are essentially two broad categories of NOI requirements-timing concerns and content concerns-both of which are set forth in MCL 600.2912b. See Driver , 490 Mich. at 257-258, 802 N.W.2d 311 (explaining the difference between the effect of a failure to comply with "the content requirements of MCL 600.2912b(4)" 8 and the effect of a failure to comply with "the notice-waiting-period requirements" on the tolling of the statute of *313 limitations); Tyra , 498 Mich. at 98 , 869 N.W.2d 213 ( VIVIANO , J., concurring in part and dissenting in part) ("Generally speaking, there are two ways in which a plaintiff can fail to comply with the notice requirements of § 2912b: timing or content."). The purpose of the requirement in MCL 600.2912b that an individual provide advance notice to a potential defendant before filing a medical malpractice complaint is to encourage settlement and reduce litigation costs. DeCosta v. Gossage , 486 Mich. 116 , 122, 782 N.W.2d 734 (2010) (opinion by WEAVER, J.); see also Bush v. Shabahang , 484 Mich. 156 , 174, 772 N.W.2d 272 (2009) (stating that the "purpose of § 2912b was to provide a mechanism for promoting settlement without the need for formal litigation, reducing the cost of medical malpractice litigation, and providing compensation for meritorious medical malpractice claims that would otherwise be precluded from recovery because of litigation costs") (quotation marks and citation omitted).

In other words, the purpose of the NOI is simply to give advance notice of the claim being made by the plaintiff to facilitate potential settlement. Thus, whether a challenge raised by a defendant is based on the timeliness of the NOI, the plaintiff's compliance with the notice waiting period, a claim that no NOI was received, or the contents of the NOI, the challenge is ultimately directed at the sufficiency of the notice received regarding the plaintiff's intent to sue. Consequently, each of these different types of challenges is just one of the possible grounds on which to challenge the sufficiency of the NOI and is essentially a challenge to the NOI. MCR 2.112(L)(2)(a) applies to "all" challenges to an NOI. This Court has recognized in the context of interpreting statutory language that "[t]here cannot be any broader classification than the word all , and all leaves room for no exceptions." Peters v. Gunnell, Inc. , 253 Mich. App. 211 , 223, 655 N.W.2d 582 , 590 (2002) (quotation marks and citation omitted; alteration in original; emphasis added); see also People v. Monaco , 474 Mich. 48 , 55, 710 N.W.2d 46 (2006) ("There is no broader classification than the word 'all.' In its ordinary and natural meaning, the word 'all' leaves no room for exceptions.") (quotation marks and citations omitted). The phrase "all challenges to a notice of intent to sue" in MCR 2.112(L)(2)(a) is therefore broad enough to encompass any of these grounds for challenging the notice given by a plaintiff, including a claim that the notice was not received. See Peters , 253 Mich. App. at 223 , 655 N.W.2d 582 . There is no language in the court rule to indicate that its application is limited only to challenges to the NOI that are based on the content of the NOI.

Next, MCR 2.112(L)(2)(a) states that these challenges to the NOI " must be made by motion, filed pursuant to MCR 2.119, at the time the defendant files its first response to the complaint , whether by answer or motion." (Emphasis added.) "The term 'must' indicates that something is mandatory." Vyletel-Rivard v. Rivard , 286 Mich. App. 13 , 25, 777 N.W.2d 722 (2009).

Thus, MCR 2.112(L)(2)(a) plainly requires a defendant to make any challenge to the sufficiency of the NOI by filing a motion at the same time that the defendant files a first response to the complaint. The language is unambiguous and must be applied as written. Decker , 307 Mich. App. at 479 , 861 N.W.2d 59 . As Chief Justice KELLY explained in concurring to the adoption of the amendment to MCR 2.112 that is at issue in this case,

[t]he amendments of MCR 2.112 and 2.118 serve to inject logic and equity into the procedural requirements governing *314 medical malpractice cases. MCR 2.112(L)(2)(a), as amended, requires a defendant to challenge a notice of intent to sue in the defendant's first response to the complaint. This is not a novel concept. Rather, it is entirely consistent with the time limits imposed on defendants asserting other affirmative defenses. See, e.g., MCR 2.116(C)(1) to (3) and (5) to (7) ; MCR 2.116(D)(1) and (2).... These limits promote judicial economy and efficiency and ensure that preliminary issues are disposed of quickly. [485 Mich. at cclxxvii ( KELLY , C.J., concurring).]

In this case, plaintiff mailed NOIs to defendants and subsequently filed a complaint against defendants alleging malpractice. After the complaint was filed, defendants claimed that they had never received an NOI from plaintiff. Defendants' attorney, Saurbier, requested a copy of the NOI from plaintiff's attorney, Turner, which Turner provided on December 28, 2015. Subsequently, MHSI and UNA filed an answer on January 15, 2016, and Dr. Veyna filed an answer on February 9, 2016. Both answers raised as an affirmative defense that plaintiff's claims were barred due to failing to properly file and provide the NOI. Then, on March 4, 2016, defendants collectively moved for summary disposition, arguing that dismissal was appropriate because they did not receive the notice required under MCL 600.2912b to commence a medical malpractice action. As previously discussed, defendants' claim that they did not receive notice constituted a challenge to the NOI, and defendants were therefore required to raise this challenge by motion filed at the time of their first response to the complaint. MCR 2.112(L)(2)(a). However, defendants did not raise this challenge by motion until March 4, 2016, well after their answers had been filed. An answer is not a "motion" under MCR 2.119 but is instead a "pleading." MCR 2.110(A)(5). There is nothing in MCR 2.112(L)(2)(a) allowing a challenge to the NOI to be preserved by including it within the affirmative defenses included in an answer. Because MCR 2.112(L)(2)(a) states that challenges to the NOI "must" be made by motion and at a specified time, these requirements are mandatory. Vyletel-Rivard , 286 Mich. App. at 25 , 777 N.W.2d 722 . By raising their challenge to the NOI in a motion filed after their answers, defendants failed to comply with MCR 2.112(L)(2)(a).

Defendants also argued in the trial court that good cause existed to justify their late challenge. Although MCR 2.112(L)(2)(a) provides that a court may allow a later challenge to the NOI "for good cause," there was no good cause in this case to justify permitting defendants' late challenge. The term "good cause" is not defined in MCR 2.112(L), and this Court therefore refers to the dictionary and to caselaw to ascertain its meaning. In re F.G. , 264 Mich. App. 413 , 419, 691 N.W.2d 465 (2004). We have previously noted that "good cause" may be defined as " '[a] legally sufficient reason,' " id ., quoting Black's Law Dictionary (7th ed.) (alteration in original), or " 'a substantial reason amounting in law to a legal excuse for failing to perform an act required by law,' " In re F.G. , 264 Mich. App. at 419 , 691 N.W.2d 465 (citations omitted).

In this case, the record shows that defendants had the necessary information to comply with the requirements of MCR 2.112(L)(2)(a) before defendants filed their answers. Although defendants denied receiving the NOIs before the complaint was filed on December 9, 2015, Turner forwarded a copy of the NOI and the cover letters to Saurbier on December 28, 2015, in response to Suarbier's request. Furthermore, the documents that Turner sent to *315 Saurbier set forth the addresses to which plaintiff sent NOIs to defendants. As previously noted, defendants filed their respective answers on January 15, 2016, and February 9, 2016, but waited until March 4, 2016, to file their motion for summary disposition arguing that plaintiff failed to provide the notice required under MCL 600.2912b. It is apparent from the record that defendants possessed the information necessary to bring such a claim at the time they filed their answers and therefore could have made a timely motion raising this challenge as required by MCR 2.112(L)(2)(a). There was no legally sufficient reason justifying defendants' failure to comply with MCR 2.112(L)(2)(a), and there was consequently no good cause to warrant allowing an untimely challenge to the NOI. In re F.G. , 264 Mich. App. at 419 , 691 N.W.2d 465 . Defendants simply neglected to follow the applicable court rule.

Nonetheless, defendants also argue that MCR 2.112(L)(2)(a) is inapplicable in this case because plaintiff could not "commence" a medical malpractice action when she failed to give defendants a timely NOI, and the court rule only applies "[i]n a medical malpractice action."

As previously stated, the statutory requirement that a plaintiff file a timely NOI is "a prerequisite condition to the commencement of a medical malpractice lawsuit," and "the failure to comply with the statutory requirement renders the complaint insufficient to commence the action." Driver , 490 Mich. at 257, 802 N.W.2d 311 (quotation marks and citation omitted). More specifically, "a medical malpractice action can only be commenced by filing a timely NOI and then filing a complaint and an affidavit of merit after the applicable notice period has expired, but before the period of limitations has expired." Tyra , 498 Mich. at 94 , 869 N.W.2d 213 . With respect to the requirement of providing a timely NOI, our Supreme Court has explained that "Michigan employs a 'mailbox rule' for providing this notice of intent." Haksluoto , 500 Mich. at 310 , 901 N.W.2d 577 . MCL 600.2912b(2) specifically provides that "[p]roof of the mailing constitutes prima facie evidence of compliance with this section."

In Saffian , 477 Mich. at 9 , 727 N.W.2d 132 , the Michigan Supreme Court addressed the question "whether defendant, who chose not to respond to a summons and complaint because he believed it was accompanied by a technically deficient affidavit of merit under MCL 600.2912d(1), ^[ 9 ^] could be defaulted." The plaintiff in Saffian had filed a medical malpractice action, and an affidavit of merit accompanied the complaint. Id . at 10, 727 N.W.2d 132 . The *316 defendant did not timely answer, and the plaintiff filed a default. Id . On appeal, the defendant argued that because the affidavit of merit was technically deficient, no action was ever "commenced," and there was therefore no duty to answer the complaint. Id . at 13, 727 N.W.2d 132 . Our Supreme Court held that "where an affidavit of merit is filed with a medical malpractice complaint, a defendant must timely answer or otherwise file some responsive pleading to the complaint, or else be subject to a default." Id . at 16, 727 N.W.2d 132 . The Saffian Court reasoned that the defendant was not authorized "to determine unilaterally whether the plaintiff's affidavit of merit satisfies the requirements of MCL 600.2912d." Id . at 13, 727 N.W.2d 132 . The Court further reasoned that an affidavit is presumed valid when it is filed, that "[i]t is only in subsequent judicial proceedings that the presumption can be rebutted," and that it is for the court to determine whether the pleadings are sufficient. Id . No such presumption would exist if no affidavit had been filed. Id . Additionally, the Saffian Court explained that "this more orderly process of honoring the presumption of the validity of pleadings," and requiring the defendant to first comply with the Court Rule requiring the timely filing of an answer before formally challenging the plaintiff's affidavit of merit, "reduces the chaotic uncertainty that allowing the defendant to decline to answer would introduce." Id . at 14, 727 N.W.2d 132 .

Saffian guides our decision in this case. Placing that case in its historical perspective helps explain why.

In Scarsella v. Pollak , 461 Mich. 547 , 549, 552-553, 607 N.W.2d 711 (2000), the Supreme Court held that a medical malpractice complaint filed without the affidavit of merit required by MCL 600.2912d was not "commenced" and therefore did not toll the running of the period of limitations. Two published decisions of this Court rapidly followed Scarsella. In both, this Court held that a defect in an affidavit of merit operated in the same manner as no affidavit at all: the underlying lawsuit was not commenced. See Mouradian v. Goldberg , 256 Mich. App. 566 , 574-575, 664 N.W.2d 805 (2003), and Geralds v. Munson Healthcare , 259 Mich. App. 225 , 240, 673 N.W.2d 792 (2003). When Saffian reached the Supreme Court in 2007, the law as established by this Court was essentially that a medical malpractice case was not commenced if the affidavit of merit accompanying the complaint was in any way defective. Nevertheless, in Saffian , 477 Mich. at 13, 14, 16 , 727 N.W.2d 132 , our Supreme Court unequivocally held that the defendant was compelled to comply with MCR 2.108(A)(6) and timely answer the complaint, despite any alleged defect in the affidavit.

In Kirkaldy v. Rim , 478 Mich. 581 , 583, 586, 734 N.W.2d 201 (2007), our Supreme Court overruled Geralds and Mouradian and held that a medical malpractice action is considered "commenced" even if the affidavit of merit filed with the complaint is defective in some respect. That our Supreme Court did not need to overrule Geralds and Mouradian when deciding Saffian underscores our Supreme Court's acknowledgment that the court rules control practice and procedure in the circuit courts. Saffian implicated a court rule that the defendant believed could be ignored because the underlying legal principal-that a malpractice case was not commenced unless the affidavit of merit met the statutory standards-would shield this choice. The defendant's "unilateral belief" in the legal rightness of his cause, however, did not save the defendant.

The case before us is analytically no different than Saffian . Here, defendants *317 unilaterally determined that plaintiff's alleged failure to mail the notices of intent to the correct addresses excused defendants from complying with the court rule governing challenges to NOIs. Like the defendant in Saffian , defendants here made that decision at their peril. Defendants' assumption that a court would ultimately agree that plaintiffs had not "commenced" this case does not excuse defendants' failure to play by the rules established by our Supreme Court, just as it did not excuse the defendant in Saffian.

In a brief order entered in Auslander v. Chernick , 480 Mich. 910 , 739 N.W.2d 620 (2007), 10 however, our Supreme Court adopted the unpublished Court of Appeals dissenting opinion in that case, which held that because the plaintiffs completely failed to attach the necessary affidavits of merit to the complaint, the defendants "were never required to raise or plead their asserted defenses in the first instance because this medical malpractice action was never properly commenced," Auslander v. Chernick , unpublished per curiam opinion of the Court of Appeals, issued May 1, 2007 (Docket No. 274079), 2007 WL 1263905 ( JANSEN , J., dissenting), p. 1.

In this case, however, plaintiff mailed NOIs to defendants, and the proof of mailing indicating that these NOIs were addressed to defendants is part of the lower court record, which provides prima facie evidence of plaintiff's compliance with the requirement to provide defendants with the required notice. MCL 600.2912b(2) ; Haksluoto , 500 Mich. at 310 , 901 N.W.2d 577 . After waiting a period of time, plaintiff subsequently filed her complaint with an affidavit of merit. Therefore, plaintiff made the necessary filings, and her actions taken as a whole also show prima facie compliance with the complete set of requirements for commencing a medical malpractice action. Tyra , 498 Mich. at 94 , 869 N.W.2d 213 . Accordingly, if defendants believed there were deficiencies that existed in plaintiff's compliance with these requirements, defendants were obligated to raise these challenges according to the appropriate procedural rules and could not unilaterally determine that plaintiff's compliance was inadequate. Saffian , 477 Mich. at 13 , 727 N.W.2d 132 . Plaintiff's NOI were presumed to be valid until rebutted in judicial proceedings in which the court could determine their legal sufficiency. See Saffian , 477 Mich. at 13, 14 , 727 N.W.2d 132 . Furthermore, defendants were not excused from the procedural requirements set forth in MCR 2.112(L)(2) because, unlike the plaintiffs in Auslander who entirely neglected to make a necessary filing, here, plaintiff complied with MCL 600.2912b by mailing notices of intent to the defendants. Accordingly, defendants in this case were entitled to challenge the sufficiency of the notice they received by claiming they never received the NOIs, but they were required to make that challenge according to the requirements of MCR 2.112(L)(2)(a). See Saffian , 477 Mich. at 13, 14, 16 , 727 N.W.2d 132 ; see also Tyra , 498 Mich. at 102 , 869 N.W.2d 213 ( VIVIANO , J., concurring in part and dissenting in part) ("Although an action may be subject to attack because it was not commenced in compliance with a statutory prerequisite, the consequences that might flow from the failure to comply with the prerequisite are not self-executing.").

*318 In conclusion, we hold that MCR 2.112(L)(2)(a) requires all challenges to the NOI to be made by motion at the time that the first response to the complaint is filed, and defendants failed to comply with this requirement. Regardless of how defendants attempt to label their challenge, it is ultimately a challenge to the NOI. Defendants forfeited their challenge to the NOI by failing to comply with the requirements of the court rule. See MCR 2.111(F)(2) (stating, in pertinent part, that a "defense not asserted in the responsive pleading or by motion as provided by these rules is waived, except for the defenses of lack of jurisdiction over the subject matter of the action, and failure to state a claim on which relief can be granted"); Roberts v. Mecosta Co. Gen. Hosp. , 466 Mich. 57 , 69, 642 N.W.2d 663 (2002) ("[A] 'forfeiture' is the failure to assert a right in a timely fashion."). Accordingly, we affirm the trial court's order granting reconsideration and denying defendants' motion for summary disposition. 11

Affirmed. Plaintiff, having prevailed, may tax costs. MCR 7.219(A).
