Briefing Sections
This briefing covers 4 sections explaining the political structures, legal frameworks, and real-world dynamics behind this process.
Section 1
The Lords reject or fail to pass a Commons bill
The Parliament Acts come into play when the House of Lords has rejected or failed to pass a bill that the House of Commons has approved. Money bills can be passed after one month without Lords consent. Other public bills require a longer process.
Section 2
The bill must pass the Commons in two successive sessions
For non-money bills, the Commons must pass the bill in two successive sessions with at least one year between the second reading in the first session and the third reading in the second session. The Lords must have rejected or failed to pass it in both sessions.
