On February 15, 1979, Patrick and Michael Eyde, owners of land in Lansing Township, filed a complaint in the Ingham Circuit Court alleging, in Count I, that numerous specified procedural defects associated with the establishment of the Remy-Chandler Drainage District, and with apportioning the cost of the Remy-Chandler Inter-county Drain among the affected municipalities, render both the drainage district and the assessments void. Count I of the complaint also challenged the constitutionality of § 536 of the Drain Code, MCL 280.536; MSA 11.1536.1 In Count II of their complaint, the Eydes alleged that the special assessment imposed on their property by Lansing Township, as part of that township’s efforts to meet its proportionate financial obligation to the Remy-Chandler Drainage District, was invalid because of various defects in the imposition of the assessment and because their property was not benefited by the drain. Count II of the complaint also challenged the constitutionality of § 539 of the *290Drain Code, MCL 280.539; MSA 11.1539.2 The complaint named as defendants Lansing Township and both the Drainage Board and the Augmented Drainage Board for the Remy-Chandler Inter-county Drain.3

*291On February 23, 1979, a petition virtually identical to the above-described complaint was filed by the Eydes in the Tax Tribunal.

On March 7, 1979, Lansing Township filed motions for summary and accelerated judgment in the circuit court. The circuit court granted the township’s motion for summary judgment as to Count I of the plaintiffs’ complaint, finding that it stated no cause of action against the township and "is more properly assertable against defendants drainage boards.” The circuit court also granted the township’s motion for accelerated judgment as to all of Count II, except for the constitutional challenge to § 539 of the Drain Code, on the ground that the subject matter of Count II, except for the § 539 challenge, was within the exclusive jurisdiction of the Tax Tribunal. The circuit court, finding that the challenge to § 539 presented no question of fact and concluding that that provision was indeed constitutional, granted the township’s motion for summary judgment on that issue.4 The Court of Appeals affirmed the decisions of the circuit court. Eyde v Lansing Twp, 105 Mich App 370; 306 NW2d 797 (1981).

Meanwhile, on February 21, 1980, the Tax Tribunal issued an order sua sponte dismissing the petition as to respondent Drainage Board and Augmented Drainage Board and denying petitioners’ motion to amend on the ground that, inter alia, the Eydes’ appeal was "untimely.”5 The Court of *292Appeals affirmed the decision of the Tax Tribunal. Eyde v Lansing Twp, 109 Mich App 641; 311 NW2d 438 (1981).

I

Lansing Township decided to raise the money needed to pay for its portion of the Remy-Chandler Drain by imposing special assessments on those properties within its boundaries which it has determined will be especially benefited by the drain. In Wikman v Novi, 413 Mich 617, 630-631; 322 NW2d 103 (1982), this Court held that challenges to special assessments of this type are within the exclusive jurisdiction of the Tax Tribunal. Because Count II of the Eydes’ complaint challenges the assessment levied by the township against the Eydes’ property, the circuit court correctly granted defendants’ motion for accelerated judgment on all but that portion of Count II which challenges the constitutionality of § 539 of the Drain Code.

The Tax Tribunal does not have the authority to invalidate acts of the Legislature. Const 1963, art 3, § 2; Wikman v Novi, 413 Mich 617, 646-647; 322 NW2d 103 (1982). As a result, the circuit court did not err in retaining jurisdiction over that portion of the Eydes’ complaint which challenged the constitutionality of § 539 of the Drain Code. Since the Eydes’ challenge to § 539 presents purely questions of law and presents no genuine issue concerning any material fact, the trial court did not err in deciding the constitutionality of that provision on a motion for summary judgment.

As for the substance of their attack on the constitutionality of § 539, the Eydes assérted in their complaint:

*293"(F) That § 539 of the Drain Code of 1956 is unconstitutional and deprives the Eydes of their due process rights under the Michigan and United States Constitutions because it provides for the preparation of the special assessment roll prior to the hearing of objections on that roll, but that it does not provide for any alteration or correction of the special assessment roll after the objection hearing.”

And argued to this Court:

"This section of the Drain Code is simply an empty right to attend a Township Board meeting and object to the Special Assessment Roll which in this case Lansing Township has little it can do as it has already been apportioned and assessed the tax. The Drain Code provides for no alteration or correction of the Roll after the objection hearing has been held.”

The Court of Appeals found that although there is no language in § 539 providing for the alteration or correction of the special assessment roll after an objection hearing, that deficiency is cured by § 4 of the township special assessment act, MCL 41.724; MSA 5.2770(54), which provides, in pertinent part:

"At the time of such hearing, or any adjournment thereof which may be without further notice, the township board shall hear any objections to the petition, if a petition is required, to the improvement and to the special assessment district, and may revise, correct, amend, or change the plans, estimate of cost or special assessment district.”

The Court of Appeals concluded that "[s]ince the opportunity for effective objection is provided, * * * it is immaterial that it is contained in a separate statute.” 105 Mich App 379. Since § 539 provides that special assessments imposed pursuant to it shall be made under the statutory or *294charter provisions governing special assessments in the public corporation to the extent applicable, we find no error in the Court of Appeals conclusion.

Finally, because Count I of the Eydes’ complaint does not state a cause of action against Lansing Township but, as the trial court said, states a claim more properly assertable against the defendant drainage boards, we find no error in the trial court’s grant of summary judgment on that point.

II

Section 31 of the Tax Tribunal Act, MCL 205.731; MSA 7.650(31), provides that the Tax Tribunal shall have exclusive jurisdiction over special assessments arising under "the property tax laws.” As the Court of Appeals determined, the final order of determination made by the Augmented Drainage Board pursuant to § 519 of the Drain Code, MCL 280.519; MSA 11.1519, and the final order of apportionment made by the Drainage Board pursuant to §§ 520 and 521 of the Drain Code, MCL 280.520; MSA 11.1520, MCL 280.521; MSA 11.1521, create an assessment on a public body and not an assessment levied against property. Accord Wikman, supra, pp 633-636. As the Court of Appeals noted,

"The public corporation is free to meet the levy in any legal way it chooses. MCL 280.526; MSA 11.1526. The public corporation — which in this instance is the township — could pay the assessment out of any funds available to the corporation — sales tax funds, general funds, ad valorem taxes, special assessments, or any combination thereof.” 109 Mich App 641, 646.

Because the Eydes’ claims against the drainage boards are outside the subject matter jurisdiction *295of the Tax Tribunal, the Tax Tribunal correctly dismissed those claims. Because of the result we reach, there is no need to decide the merits of the Eydes’ challenge to § 536 of the Drain Code.

The judgments of the Court of Appeals, in both cases, are affirmed.

(dissenting). The Eydes commenced actions in the circuit court and the Tax Tribunal alleging that the township excessively assessed their property, that the drainage boards failed to follow certain organizational and operational procedures, and that the notice provisions of the Drain Code were violative of the Due Process Clause.

The opinion of the Court affirms decisions of the Court of Appeals1 holding that the circuit court action against the township alleging an excessive assessment can be maintained only in the Tax Tribunal and that the challenge to the operation of the boards can be pursued only in the circuit court. This Court finds no violation of the constitution.

Because the Drain Code is not a property tax law and thus special drainage assessments are not levied under a "property tax law,”2 we would hold that the Eydes may maintain an action against the township in the circuit court challenging the *296assessment against their property. We also conclude that the notice provided did not satisfy the requirements of the Due Process Clause.

I

The Eydes contend that as property owners subject to assessment by the township they were entitled to personal notice of the hearings at which the drainage boards approved the proposed drain improvement and apportioned the costs among the affected municipal corporations.3 We agree and would reject Fair Drain Taxation, Inc v St Clair Shores, 219 F Supp 646 (ED Mich, 1963), which held that such notice is not required.

The assessment arises out of a drain improvement.4 The location of the proposed drain improvement was known, and the boards could readily have determined which property owners would or might be specially assessed to pay for the improvement. While it is true that the township had the legal authority to finance the improvement by means other than a special assessment,5 it is also true, that, as a practical matter, it would not do so. Few townships possess the financial means to finance such a project with ordinary revenues.

While it was not certain at the early stages of the proceedings that property owners such as the Eydes would be specially assessed, it clearly was probable that they would be. The Eydes might not *297be able to avoid assessment unless they protested the approval of the project. Because the boards failed to provide the Eydes with reasonable notice of the hearings, the Eydes were not given a meaningful opportunity to object, and they were thereby denied due process of law.

II

The Court, on the authority of Wikman v Novi, 413 Mich 617; 322 NW2d 103 (1982), declares that "challenges to special assessments of this type are within the exclusive jurisdiction of the Tax Tribunal.” Wikman,6 however, concerned a special assessment for road improvements levied under the authority of the Home Rule Act,7 and not a special drain assessment levied pursuant to the Drain Code.8

The Drain Code, in contrast with the Home Rule Act, contains special notice and assessment provisions pertaining both to apportionment of costs by boards9 and to special assessments by municipal corporations.10 These procedures were designed to expedite litigation that might delay the sale of bonds to finance construction.11 In adopting the Tax Tribunal Act, the Legislature did not intend to substitute for the specially designed, relatively *298expeditious procedures of the Drain Code the more time-consuming procedures of the Tax Tribunal.

Because the Tax Tribunal provides "de novo” review of the apportionment of benefits as well as of a claim that there is no benefit at all,12 it seems likely that opportunities for delay will increase and appeals will multiply. This is contrary to the legislative goal of reducing such obstacles to the construction of a drain.

Ill

The opinion of the Court holds that the Tax Tribunal lacks jurisdiction to hear the Eydes’ claim against the boards because the boards assessed the apportioned costs to the affected municipal corporations (including the township) and not against the real property alleged to have been benefited by the improvement. This ruling avoids making the Tax Tribunal the forum for review of apportionment in the instant case, but only because the assessment is in respect to an inter-county drain and the boards chose to apportion costs under chapter 21 of the Drain Code and not under chapter 25.

The Drain Code vests the exclusive power to apportion and assess the costs of an intracounty drain in drainage boards.13 Boards may and generally do assess the costs after apportionment directly to specific parcels of land.14 Such assessments would, in the majority view, be property taxes levied under property tax laws reviewable in *299the Tax Tribunal. The determination of the proper forum to protest a board’s apportionment thus will henceforth depend on whether the drain is intra- or intercounty. There is no reason to suppose that the Legislature intended for disputes involving apportionment to be resolved in separate forums with different procedures depending on whether the drain is intra- or intercounty.

Under the alternative apportionment method set forth in chapter 25, which may be employed for both intra- and intercounty drains, a board apportions costs on the basis of "the relative valuations, as equalized,” of each municipal corporation.15 Apportionment based on the equalized valuation of property seems, under the majority’s reading of Wikman, to be a property tax levied under a property tax law and therefore within the exclusive jurisdiction of the Tax Tribunal. Yet nothing in the Drain Code suggests that the Legislature intended that a chapter 25 apportionment of the costs of an intercounty drain be treated differently than a chapter 21 apportionment of the costs of an intercounty drain. Chapter 25 is rather required to "be construed to be integrated with chapters 20 and 21.”16 Tax Tribunal review of chapter 25 apportionments requires a board apportioning the cost of an intercounty drain to choose between a possibly more expeditious method of apportionment (chapter 21, reviewable in the circuit court) and a method of apportionment that might appear to the board to be more appropriate in the circumstances (chapter 25, reviewáble in the Tax Tribunal).

Tax Tribunal review of board decisions will hamper the construction of drains. Instead of the *300ten-day period provided in the Drain Code,17 protesters will now have thirty days to seek review.18 Because Tax Tribunal procedure provides for de novo review,19 and, unlike the Drain Code,20 does not provide for the assessment of costs,21 review may be employed as a delaying tactic.

IV

The Legislature provided special procedures for drain assessments because drains "are necessary for the public health”22 and are a matter of "primary public concern.”23 The regulation of the public health is a matter within the police power of the state,24 and accordingly drain assessments may be within the "police power” exception noted in Wikman.25
