Repeal and savings preserve accrued tax liabilities and ongoing proceedings despite repeal of specified State tax laws and prior ordinance. The Act repeals specified State tax enactments while preserving accrued rights, obligations and liabilities and maintaining enforceability of taxes, surcharges, penalties, fines, interest, forfeitures and punishments. Investigations, assessments, adjudications and all proceedings including appeals, revisions and reviews may be instituted or continued and recoveries enforced as if the repealed or amended Acts remained in force. Tax exemptions issued by notification cease to operate as privileges if rescinded on or after the appointed day. Actions under the earlier GST Ordinance are deemed to have been taken under this Act.
