85.5. If the city council considers it to be in the general interest of the city, it may declare, in respect of all the boroughs and for a period it determines, that the exercise of a jurisdiction or power assigned by law to all the borough councils is within its jurisdiction.
The resolution by which the council makes the decision is adopted by an absolute majority vote of the council members. However, the resolution is adopted by a two-thirds majority vote of the council members if the period for which the council declares its jurisdiction exceeds two years or if the resolution extends the application of a declaration of jurisdiction so as to render it applicable for a period exceeding two years.
