Prorogation
Prorogation is the procedural act by which a session of a parliament in Westminster-derived systems is formally terminated, suspending legislative business until the commencement of the subsequent session.[1] It differs from dissolution, which ends the entire parliamentary term and triggers elections, as prorogation preserves the existence of the legislature while halting its proceedings, including the lapse of unfinished bills unless provisions for carryover exist.[2][1] Initiated by the executive—typically the prime minister—and executed through a proclamation by the head of state or viceroy, prorogation historically served to structure parliamentary calendars, allowing recesses for reflection or elections without fully interrupting the body's mandate.[1][2] In practice, it clears the legislative agenda, nullifying pending questions, motions, and committees, though select carryover mechanisms have been introduced in jurisdictions like the United Kingdom to mitigate disruptions.[2] While routine in most cases, prorogation's exercise of prerogative power has sparked controversies when perceived as a tool to evade scrutiny, as evidenced by judicial interventions affirming limits on its duration and purpose; for instance, Canada's 2008 prorogation delayed a confidence vote amid government-minority tensions, and the United Kingdom's 2019 five-week prorogation was ruled unlawful by the Supreme Court for excessively frustrating Parliament's ability to hold the executive accountable.[3] These episodes underscore prorogation's dual role as both administrative necessity and potential check on legislative oversight, with courts increasingly scrutinizing its justiciability under constitutional conventions.[4]Definition and Purpose
Core Mechanisms and Effects
Prorogation is effected through a royal prerogative exercised by the Crown, typically on the advice of the prime minister, via a formal proclamation that declares the end of the current parliamentary session.[2] This proclamation is read in both the House of Commons and the House of Lords (or equivalent chambers in other Westminster systems), immediately terminating all active parliamentary proceedings without requiring legislative approval.[5] Unlike dissolution, which ends the parliament entirely and triggers elections, prorogation preserves the existence of the legislature, allowing members to retain their seats until a subsequent dissolution.[6] The core effect of prorogation is the suspension of legislative and oversight functions, clearing the order paper of unfinished business. Bills that have not received royal assent lapse entirely, with no automatic carry-over between sessions unless specific statutory provisions apply in exceptional cases, such as certain money bills or hybrid procedures in jurisdictions like Canada.[2] [7] Select committees and their investigations are dissolved, though final reports may be tabled for reference in the next session; motions, questions, and debates are dropped, halting direct parliamentary scrutiny of the executive.[5] During prorogation, the government continues to operate administratively and can issue orders in council or secondary legislation, but it faces reduced accountability as Parliament cannot convene for debates, votes of confidence, or inquiries.[2] This mechanism allows the executive to reset the legislative agenda for the forthcoming session, often aligning it more closely with government priorities, though prolonged prorogations—such as the five-week period ordered in the United Kingdom on August 28, 2019—can limit Parliament's influence over urgent matters like budgetary approvals or treaty ratifications.[2] In practice, sessions typically last one to two years before prorogation, with the timing strategically chosen to avoid defeats on key legislation.[5]Distinctions from Related Parliamentary Actions
Prorogation terminates a parliamentary session without ending the Parliament itself, allowing the same members to convene for a subsequent session, whereas dissolution concludes the entire Parliament and mandates a general election to form a new one.[2][8] During prorogation, all unfinished legislative business, such as pending bills and motions, lapses and must be reintroduced in the new session, but select committees may continue their work or report findings.[2] In contrast, dissolution not only halts all parliamentary proceedings but also vacates all seats, requiring MPs to seek re-election.[8] Adjournment differs from prorogation as it represents a temporary interruption within an ongoing session, permitting Parliament to resume business without resetting the legislative agenda or lapsing bills.[9] Prorogation, by ending the session, imposes a more definitive pause, during which neither House nor committees typically meet, though certain documents can still be laid before Parliament.[10] Adjournments can occur daily, for recesses, or over holidays, maintaining continuity, whereas prorogation aligns with annual cycles to structure sessions around the legislative program, such as following the State Opening.[1]| Parliamentary Action | Effect on Session | Effect on Parliament | Impact on Legislation and Business | Leads to Election? |
|---|---|---|---|---|
| Prorogation | Ends current session; new session follows | Continues with same members | Unfinished bills lapse; motions die; committees may persist | No[2][9] |
| Dissolution | Ends session and entire term | Terminates; seats vacated | All business ceases; new Parliament starts anew | Yes[8] |
| Adjournment | Temporary pause within session | Unaffected | Business resumes without lapse | No[9] |
