REARDON, J.
The petitioners, residents, taxpayers, and duly registered voters in Cambridge, have petitioned for a writ of mandamus. The facts are not in dispute.
Cambridge has a Plan E form of government conformable to G.L.c. 43, §§ 93-116, as amended, and is the only city or town in the Commonwealth where officers are elected by proportional representation or preferential voting. The respondent was in the process of preparing a question contained in St. 1972, c. 596, § 3, to be placed on the official ballot for the November 7, 1972, biennial State election in Cambridge. The question described in § 3 will not appear on the ballot in any other city or town in the Commonwealth. Statute 1972, c. 596, which was enacted over the veto of the Governor, provides as follows:
"SECTION 1. Section one hundred and fifteen of chapter forty-three of the General Laws is hereby repealed.
"SECTION 2. Chapter fifty-four A of the General Laws is hereby repealed.
*532 "SECTION 3. The state secretary shall cause the following question to be placed on the official ballot to be used at the biennial state election in each city in which voting by proportional representation or preferential voting is in effect: 
 "`Shall the elective officers of this city be  _________
nominated by preliminary election and elected      YES.
by ordinary plurality voting?'                  _________
                                                    NO.
                                                _________
"The state secretary shall cause the following question to be placed on said ballot in each town in which voting by proportional representation or preferential voting is in effect: 
 "`Shall the elective officers of this town be   _________
elected by ordinary plurality voting?'             YES
                                                 _________
                                                    NO.
                                                 _________
"If a majority of the votes in answer to such question by any such city or town is in the affirmative elective officers in such city or town shall thereafter be nominated and elected in the manner provided in said question.
"If a majority of the votes in answer to said question is in the negative those elective officers who, on the date of said election, were elected by proportional representation or preferential voting shall continue to be so elected."
Statute 1972, c. 596, was not enacted (1) on a petition filed or approved by the voters or by the city council of Cambridge, or (2) by a two-thirds vote of each branch of the General Court following a recommendation by the Governor.
The contention of the petitioners is that because St. 1972, c. 596, was enacted in violation of art. 89 of the Amendments to the Constitution of the Commonwealth (the home rule amendment),[1] it has no force and effect, and the respondent is under a duty not to place the question described in § 3 therein on the official ballot in Cambridge for the biennial State election to be held on November 7, 1972.
*533 Section 1 of art. 89 provides, "It is the intention of this article to reaffirm the customary and traditional liberties of the people with respect to the conduct of their local government, and to grant and confirm to the people of every city and town the right of self-government in local matters, subject to the provisions of this article and to such standards and requirements as the general court may establish by law in accordance with the provisions of this article" (emphasis supplied).
The provisions limiting the power of the Legislature are to be found in § 8 of the article.[2] On its face it is plain that St. 1972, c. 596, can be classified as a law "in relation to cities and towns" and therefore subject to the restrictions of § 8. If it be a special law, it is unconstitutional since it was not enacted on a petition filed or approved by the voters or by the city council of Cambridge or by a two-thirds vote of each branch of the General Court following a recommendation of the Governor.
If on the other hand c. 596 can be viewed as a general law applicable "to a class of not fewer than two" cities and towns, there being no obstacle in art. 89 to the enactment of such laws, it is constitutional.
The basic issue thus is whether St. 1972, c. 596, by its terms applicable to a class of "all" cities having proportional *534 representation but in fact only to Cambridge, is to be characterized as a general law applicable to a class of not fewer than two or as a special law within the meaning of § 8 of art. 89.
In Opinion of the Justices, 356 Mass. 775, we stated that legislation for a multi-purpose stadium, tunnel and an arena was, in most of its aspects, regional legislation having some State-wide effect and was not to be considered as a law "in relation to cities and towns," and therefore was not subject to the requirements for either general or special laws specified in § 8. We there noted, "We do not interpret the words `to act in relation to cities and towns' as precluding the Legislature from acting on matters of State, regional, or general concern, even though such action may have special effect upon one or more individual cities or towns. If the predominant purposes of a bill are to achieve State, regional, or general objectives, we think that, as heretofore, the Legislature possesses legislative power, unaffected by the restrictions in art. 89, § 8. On the other hand, in instances where the primary purpose of a major and severable portion of a bill, otherwise enacted for State, regional, or general purposes, is to legislate `with respect to ... [the] local government,' or `local matters,' of a particular city or town, it may be necessary to consider whether in the particular circumstances that severable major portion complies with § 8 of art. 89." Pp. 787-788.
In our view the last quoted sentence is fully applicable to c. 596, § 3. That section provides for a question to be placed on a municipal ballot which, if approved by the voters in Cambridge, will alter the method by which the city council and the school committee are elected in that city. It is directly and solely concerned with altering a crucial feature of municipal government. If the words "in relation to cities and towns" are to be given any meaning they must be applicable to this statute. Therefore, c. 596, § 3, must be subject to the requirements of art. 89, § 8.
We thus consider whether c. 596, § 3, applies alike *535 "to all cities, or to all towns, or to all cities and towns, or to a class of not fewer than two." That c. 596, § 3, is phrased in general terms, and is, arguably, potentially applicable to cities in addition to Cambridge at some indefinite future time, is not sufficient to meet the test which § 8 of art. 89 establishes. When enacted, c. 596, § 3, was applicable in fact only to Cambridge. That it was phrased in general or specific terms does not control under § 8, which prescribes a clear and simple test of minimum applicability. In Opinion of the Justices, 357 Mass. 831, we pointed out relative to an act affecting the towns of Southwick and West Springfield that it met the test of a general law within the meaning of the first sentence of art. 89, § 8, and, hence, did not need to be enacted in accordance with the special procedures for special laws there defined. That case involved two towns, a situation quite different from that which confronts us here.
We said in Mayor of Gloucester v. City Clerk of Gloucester, 327 Mass. 460, 464, "No municipality has any vested right in its form of local government. All such matters are subject to the paramount authority of the Legislature, which may change, and even abolish, at will." However, the relevance of this and other cases decided prior to 1966 has been considerably diminished, if not erased. The adoption of art. 89 "effected substantial changes in the legislative powers of the General Court and the cities and towns." Opinion of the Justices, 356 Mass. 775, 787.
In sum, art. 89 was adopted by the people to prevent precisely the type of legislation which is represented by St. 1972, c. 596, § 3.
It is for this reason that, by our order dated October 6, 1972, we have directed the issuance of a peremptory writ of mandamus commanding the respondent not to print the question contained in St. 1972, c. 596, § 3, on the official ballot for the biennial State election of Cambridge.
