The passage of legislation in the House of Commons involves multiple stages. A bill must pass through both the House of Commons and House of Lords in the same form to become law, and receive Royal Assent. A bill can start in either chamber. In the Commons, there is a first reading, second reading and debate, committee stage involving a Public Bill Committee or Committee of the Whole House, report stage, and third reading. A bill then passes to the Lords. Private Members' bills follow a different process without programming. Public involvement can occur through consultations and providing evidence to committees.
