Plaintiffs filed this action to test the constitutionality of PA 1967, No 239, MCLA § 388.711 et seq. (Stat Ann 1968 Cum Supp § 15.2299[51] et seq.). June 14, 1968, the trial court granted defendants’ motion for summary judgment and plaintiffs appeal.

The act involved deals with emergency reorganization of primary and fourth class school districts not maintaining high schools lying wholly in, or the major part of the territory of which lies wholly in, a county of more than 1,000,000 population. By its terms, the act was not effective after July 1, 1968. PA 1967, No 239, § 11. As amended by PA 1968, No 130, § 2, the limitation on the term of the effectiveness of the act was repealed and it was made effective without limit. Plaintiff school district lies wholly in Monroe county and the individual plaintiffs are resident taxpayers of the district,

*576 It is plaintiffs’ position that by its terms, Act 239 applies only to school districts in Wayne county, and, therefore, it is a local and special act in violation of Const 1963, art 4, § 29, * because a general act could have been made applicable and the voters of the district did not approve the act.

The fact that a legislative act contains a population classification which limits the present application of the act does not necessarily mate the act local or special. If the population classification has a reasonable relation to the purpose of the statute and the statute applies whenever the population classification is met, an act containing such a classification is not thereby made local or special. City of Dearborn v. Wayne County Board of Supervisors (1936), 275 Mich 151; Chamski v. Wayne County Board of Auditors (1939), 288 Mich 238; The Irishman’s Lot, Inc. v. Secretary of State (1954), 338 Mich 662.

As amended, Act 239 applies to all counties attaining a population of more than 1,000,000.

The large number of high school students to be found in non-high school districts in a populous area as opposed to the smaller number in a less populous area and the improbability of relief through annexation or consolidation establish the reasonable relation of the population classification to the purpose of the statute.

The substantial questions of fact on which plain tiffs rely in support of their contention that sum *577 mary judgment was improper do not relate to the legal issue that disposes of this appeal.
