Repealing and amending legislation preserves existing rights while repealing listed enactments and revising targeted statutory language. Repealing and Amending Act, 1974 repeals the enactments listed in the First Schedule to the extent specified there and amends the enactments listed in the Second Schedule to the extent and in the manner specified in that Schedule. It also makes a specific amendment to the Sixth Schedule to the Constitution by substituting 'cattle pounds' for 'cattle ponds' in paragraph 6, and includes a saving clause preserving prior acts, rights, liabilities, remedies, proceedings, and existing legal principles.
