Saving provision preserves pre repeal rights, investigations, and tax recovery mechanisms, permitting continuation as if repeal had not occurred. A saving provision preserves accrued rights, obligations and liabilities despite repeal, prevents revival of matters not in force, and provides that tax exemptions notified but rescinded on or after the appointed day do not continue as privileges; it also permits institution and continuance of investigations, audits, assessments, adjudications, appeals and recovery of taxes, penalties and related remedies as if the repealed Acts had not been repealed.
