The Executive & Parliament
The Whip System: Political parties use 'whips' to maintain discipline, ensuring that MPs vote in accordance with the government's agenda, which often guarantees a majority for executive proposals.
Agenda Setting: The executive largely controls the parliamentary timetable, prioritizing its own legislative program and limiting the time available for opposition or backbench initiatives.
Prerogative Powers: These are powers historically held by the monarch but now exercised by the executive, such as declaring war or making treaties, often without the need for prior parliamentary consent.
Secondary Legislation: The executive can use 'statutory instruments' to make detailed changes to the law without the full scrutiny required for primary legislation, further increasing its influence.
Revising Chamber: The House of Lords acts as a secondary check, focusing on technical amendments and the long-term implications of legislation rather than short-term political gain.
Delaying Power: Under the Parliament Acts, the Lords can delay non-financial legislation for up to one year, forcing the executive to reconsider or compromise on controversial bills.
Constitutional Limitations: The Lords cannot block 'money bills' (financial legislation) and, by convention, do not oppose legislation that was promised in the government's election manifesto.
| Feature | Constitutional Theory | Political Practice |
|---|---|---|
| Sovereignty | Parliament is supreme and can dismiss the government. | The executive often dominates due to a stable majority. |
| Legislation | Parliament debates and creates laws independently. | Most laws are initiated and pushed through by the executive. |
| Scrutiny | Committees and questions provide rigorous oversight. | Party loyalty and the whip system can weaken scrutiny. |
Analyze the Majority: When evaluating executive power, always consider the size of the parliamentary majority; a small or non-existent majority significantly increases Parliament's leverage.
Distinguish Scrutiny from Control: Remember that while Parliament has many ways to scrutinize (ask questions), it has fewer ways to control (stop) an executive with a strong mandate.
Check for Conventions: Be aware of unwritten rules, like the Salisbury Convention, which limit the House of Lords' ability to block the executive's primary policy goals.
Common Mistake: Do not assume that 'Parliamentary Sovereignty' means Parliament is always in charge; in practice, the executive is the 'efficient' part of the constitution that drives the state.
