Bills are draft laws that are debated in Parliament and passed (or not) as Acts. Early Bills were published in the Government Gazettes. We have separate print versions of Bills from the 1970's onwards. For recent years the Bills are online on the South African Government website, the Parliamentary Monitoring Group website, Sabinet Legal's Parliamentary Bills and Sabinet's Bill Tracker database.
Acts are the laws passed by Parliament. When consolidated they are referred to as Statutes. The Acts are published in the Government Gazettes. We have annual volumes of Acts. For recent years individual Acts are available on the South African Government website and Sabinet's Government Gazettes database. Be aware that the current consolidated versions of Acts are available in databases, Netlaw, LexisNexis South Africa and the University of Pretoria's Laws of South Africa: Consolidated Legislation.
Regulations and Government Notices are subsidiary legislation published by Government Departments in the Government Gazette. The current and retrospective Gazettes are available through Sabinet and LexisNexis. We have the Gazettes in print until 2012.
