(a) Petition lacking signatures.--If it appears that the petition under this subchapter has not been signed by the required number of electors, no action shall be taken. The ordinance shall be taken to be in full force from the time or times it would have gone into effect had there been no petition against the ordinance.

(b) Reconsideration.--Council must reconsider an ordinance if the petition is signed by a number of electors equal to 20% of all the votes cast for mayor. If the ordinance is not entirely repealed by council on reconsideration, council must call a referendum to be held at the time of the next general, municipal or primary election occurring at least 60 days after the reconsideration.

(c) Submission.--At the election, the ordinance shall be submitted without alteration in accordance with the Pennsylvania Election Code.
