Repeal and savings provisions preserve existing rights and legal effects despite statutory repeal and avoid reviving obsolete powers. Listed enactments are repealed to the extent indicated, but repeal preserves the validity and proof of past acts, protects rights, titles, obligations, liabilities, remedies, proceedings, releases, discharges and indemnities already acquired or incurred, and preserves existing legal principles, jurisdictions, forms of pleading, practices, procedures, usages, customs, privileges, restrictions, exemptions, offices and appointments; repeal does not revive matters not in force and does not limit the General Clauses Act on effects of repeals.
