No ordinance of any municipality granting any lease of, or consent, permit, or right to use such subways for local transportation purposes shall become operative until a proposition to approve the ordinance has been submitted to the electors of the municipality and has been approved by a majority of the electors voting upon the proposition. Every such ordinance shall order such submission and shall designate the election at which the proposition is to be submitted. The municipal clerk shall promptly certify such ordinance and proposition for submission.
The proposition need not include the ordinance in full but shall indicate the nature of the ordinance, and shall be substantially in the following form:
-------------------------------------------------------------------- Shall the ordinance passed by the city council (or board of trustees) of (name of municipality) on YES (insert date), entitled ...., which grants to (name of grantee) --------------------------- a lease of (or consent, permit, or right to use, as the case may be) NO of the municipally owned subways therein specified, for local transportation purposes, be approved? --------------------------------------------------------------------
However, when any municipality by ordinance grants a permit to construct and operate or maintain and operate a local transportation system, including the use of municipally owned subways, and that ordinance is submitted to and approved on a referendum, it is not necessary to pass or to submit to a referendum a separate ordinance granting a lease of or consent, permission, or right for the use of those subways.
