No prosecution or action resulting from a violation of zoning regulations heretofore
in effect shall be abated or abandoned by reason of the enactment of any ordinance
amendment, but shall be prosecuted to finality under the former provisions, the same
as if the amendment had not been adopted and, to this end, the former provisions shall
remain in effect and be applicable until said prosecution or action has been terminated.
Any violation that occurred prior to the effective date of the amendment, for which
prosecution or legal action has not been instituted prior to the effective date of
the amendment, may be hereafter subject to prosecution or action as if the amendment
had not been adopted and, to this end, the former provisions shall remain in effect
and be applicable until said prosecution or action has been terminated.
