Article VIII
Sec. 31: The legislature shall by general law provide for the incorporation by any two or more cities, villages or townships, or any combination or parts of same, of metropolitan districts comprising territory within their limits, for the purpose of acquiring, owning and operating either within or without their limits as may be prescribed by law, parks or public utilities for supplying sewage disposal, drainage, water, light, power or transportation, or any combination thereof, and any such district may sell or purchase, either within or without its limits as may be prescribed by law, sewage disposal or drainage rights, water, light, power or transportation facilities. Any such districts shall have power to acquire and succeed to any or all of the rights, obligations and property of such cities, villages and townships respecting or connected with such functions or public utilities: Provided, That no city, village or township shall surrender any such rights, obligations or property without the approval thereof by a majority vote of the electors thereof voting on such question. Such general law shall limit the rate of taxation of such districts for their municipal purposes and restrict their powers of borrowing money and contracting debts. Under such general law, the electors of each district shall have power and authority to frame, adopt and amend its charter upon the approval thereof by a majority vote of the electors of each city, village and township, voting on such question, and, through its regularly constituted authority, to pass all laws and ordinances relating to its municipal concerns, subject to the constitution and general laws of this state.
