Any township located outside the territory of a county in which a Metropolitan Airport Authority is established, but which was included in a pre-existing airport authority which has been acquired by the Metropolitan Airport Authority, may disconnect from such Authority and have the annual tax levy discontinued by referendum, provided that the governing board of the township and the governing bodies of any municipalities with a population greater than 5,000 located within such township have adopted like ordinances or resolutions recommending disconnection from the authority. The ordinances or resolutions shall provide that the question of disconnection be submitted to the electors of the township. Upon the adoption of such ordinance or resolution, the clerk of the township or municipality shall certify the ordinance or resolution and the question to the proper election officials who, upon certification of all the required ordinances or resolutions, shall submit the question to the electors of the township at an election in accordance with the general election law. In the event that a municipality with a population over 5,000 inhabitants lies within more than one township, then for the purpose of the referendum provided for in this Section the municipality as a whole shall vote on the proposition of the township in which the majority of the population of the municipality is located.
