It is the purpose of this act to revise and reorganize the Charter of the City of Hamlet (North Carolina Private Laws 1897, chapter 14) and to consolidate into it certain local acts concerning the property, affairs, and government of the City of Hamlet, including the following acts: North Carolina Session Laws, 1959, chapter 851, providing for nonpartisan primaries; and North Carolina Session Laws 1963, chapter 908, and North Carolina Session Laws 1967, chapter 542, relating to municipal elections. It is intended to continue in force without interruption those provisions of prior local acts which are consolidated into this act, so that all rights and liabilities that have accrued are preserved and may be enforced.
