📚 The Influence and Effectiveness of the Executive in Attempting to Exercise Dominance over Parliament | 行政机构试图对议会行使支配权的影响与有效性
In the UK Westminster model, the executive is drawn from Parliament and normally commands a majority in the House of Commons. This fusion of powers gives the prime minister and cabinet powerful tools to dominate the legislative process. Yet the effectiveness of that dominance is not absolute: parliamentary scrutiny, party rebellions, the House of Lords, and external legal constraints can all limit executive control. This article examines how the executive attempts to exercise dominance over Parliament and evaluates how effective those attempts are under different political conditions.
在英国威斯敏斯特模式下，行政机构产生于议会，并且通常在下议院拥有多数席位。这种权力融合赋予首相和内阁主导立法过程的强大工具。然而，这种支配的有效性并非绝对：议会审查、党内反叛、上议院以及外部法律约束都可能限制行政机构的主导权。本文将考察行政机构如何试图对议会行使支配权，并评估在不同政治条件下这些尝试的有效性。
1. The Fusion of Powers and Executive Dominance | 权力融合与行政主导
The UK constitution is based on a fusion of powers rather than a strict separation. Ministers are members of the legislature and the government normally relies on a disciplined majority in the Commons. This structural feature means the executive can usually pass its legislative programme without needing cross-party support.
英国宪法建立在权力融合而非严格分权的基础上。大臣本身是立法机关成员，政府通常依靠下议院中纪律严明的多数党。这一结构性特点意味着行政机构通常无需跨党派支持即可通过其立法计划。
The absence of codified constitutional limits also strengthens the executive. Unlike the US president, the UK prime minister is not subject to a written constitution enforced by a constitutional court, so parliamentary procedures and political norms are the main formal constraints.
缺乏成文宪法限制也增强了行政机构的权力。与美国总统不同，英国首相不受成文宪法和宪法法院的约束，因此议会程序和政治惯例是主要的形式约束。
2. Majority Government and Party Discipline | 多数党政府与政党纪律
The most reliable source of executive dominance is a large Commons majority. When a party controls more than half the seats, the government can usually win votes on legislation, budgets, and confidence motions. Party discipline, enforced through whips, ensures that most MPs follow the party line.
行政主导最可靠的来源是下议院的大多数席位。当一个政党控制超过半数议席时，政府通常能在立法、预算和信任动议投票中获胜。通过党鞭执行的政党纪律确保大多数议员遵循政党路线。
The payroll vote further increases executive influence. Around 140 MPs hold paid government or party positions, and they are expected to support the government or resign. This creates a loyal bloc that reduces the chance of defeat.
领薪投票进一步增强了行政机构的影响力。约 140 名议员担任有薪的政府或政党职务，他们被期望支持政府，否则需辞职。这形成了一个忠诚的集团，降低了政府被击败的可能性。
3. Control of the Legislative Agenda | 对立法议程的控制
The executive dominates the parliamentary timetable. The government decides which bills are debated, how much time is allocated, and when votes take place. Private members’ bills have little chance of becoming law without government backing.
行政机构主导议会时间表。政府决定哪些法案被辩论、分配多少时间以及何时投票。如果没有政府支持，普通议员法案几乎没有机会成为法律。
Government bills are drafted by departments and often benefit from the expertise of the civil service, whereas opposition and backbench MPs lack equivalent resources. This asymmetry makes effective challenge difficult.
政府法案由各部门起草，通常受益于公务员的专业知识，而反对党和后座议员缺乏同等资源。这种不对称使得有效挑战变得困难。
4. The Role of Select Committees and Parliamentary Questions | 专门委员会与议会质询的作用
Parliament does possess scrutiny tools. Departmental select committees can call ministers and civil servants to give evidence, produce reports, and make recommendations. These committees, chaired by backbenchers, sometimes embarrass the government and shift public debate.
议会确实拥有审查工具。部门专门委员会可以传唤大臣和公务员提供证据、撰写报告并提出建议。这些由后座议员主持的委员会有时会使政府难堪并改变公共讨论方向。
However, their effectiveness is limited by the lack of binding power. The government is not obliged to accept committee recommendations, and committees cannot veto legislation or spending. Ministerial questions also provide only brief, often evasive answers.
然而，其有效性因缺乏约束力而受限。政府没有义务接受委员会建议，委员会也不能否决立法或开支。大臣质询也只提供简短且常常回避的回答。
5. Backbench Rebellions and Intra-Party Divisions | 后座议员反叛与党内分歧
Even with a majority, the government can face rebellions from its own backbenchers. Large majorities may embolden MPs to vote against the government on issues such as Brexit, welfare reform, or military action, because a few defections will not bring down the government.
即使拥有多数席位，政府也可能面临本党后座议员的反叛。大规模多数席位可能鼓励议员在脱欧、福利改革或军事行动等议题上投反对票，因为少量背叛不会推翻政府。
The effectiveness of executive dominance therefore depends on the size of the majority and the cohesion of the governing party. A small majority makes every rebellion dangerous; a large but divided party can still suffer high-profile defeats.
因此，行政主导的有效性取决于多数席位的规模以及执政党的团结程度。微弱多数使每一次反叛都充满危险；而庞大但分裂的政党仍可能遭受引人注目的失败。
6. The House of Lords as a Constraint | 上议院作为制约
The House of Lords can delay legislation and force the government to reconsider. Although the Lords cannot permanently block bills, it can inflict political damage, especially when cross-bench peers and opposition parties unite against a controversial measure.
上议院可以拖延立法并迫使政府重新考虑。尽管上议院不能永久阻止法案，但它能造成政治伤害，特别是当中立议员与反对党联合反对某一有争议的措施时。
The Parliament Acts 1911 and 1949 limit the Lords’ power to a one-year delay for most bills, and financial bills are exempt. Nevertheless, the Lords often wins concessions because the government wishes to avoid delay and bad publicity.
1911 年和 1949 年议会法将上议院的权力限制为对大多数法案最多延迟一年，财政法案则不受此限制。尽管如此，上议院往往能赢得让步，因为政府希望避免拖延和负面宣传。
7. Royal Prerogative and Executive Action | 王室特权与行政行为
Historically, the executive has used royal prerogative powers to act without prior parliamentary approval, for example in deploying troops, signing treaties, and granting honours. These powers allow the prime minister to bypass parliamentary votes.
历史上，行政机构利用王室特权在未获议会事先批准的情况下采取行动，例如部署军队、签署条约和授予荣誉。这些权力使首相能够绕过议会投票。
However, parliamentary assertiveness has increased. Since the 2003 Iraq War vote and the 2011 Libya intervention, there is a strong convention that the Commons should approve major military action. Treaties are also subject to greater scrutiny under the Constitutional Reform and Governance Act 2010.
然而，议会的主动性有所增强。自 2003 年伊拉克战争投票和 2011 年利比亚干预以来，下议院应批准重大军事行动已成为强有力的惯例。根据 2010 年宪法改革与治理法，条约也受到更严格的审查。
8. Coalition and Minority Government: Reduced Dominance | 联合政府与少数党政府：主导权减弱
Executive dominance is most effective under a single-party majority government. In a coalition, the prime minister must negotiate with coalition partners, and the smaller party can veto policies or threaten to collapse the government.
行政主导权在一党多数政府下最为有效。在联合政府中，首相必须与联合伙伴谈判，较小的政党可以否决政策或威胁使政府垮台。
Minority governments face even greater constraints because they cannot guarantee winning votes. They must build ad hoc alliances with other parties, which dilutes the executive’s agenda and strengthens Parliament’s influence over legislation.
少数党政府面临更大的制约，因为它们无法保证赢得投票。它们必须与其他政党建立临时联盟，这削弱了行政议程并增强了议会对立法的影响力。
9. Fixed-term Parliaments and Dissolution | 固定任期议会与解散权
Before 2011, the prime minister could choose the election date, using the threat of dissolution to discipline MPs. The Fixed-term Parliaments Act 2011 removed this power, but the Dissolution and Calling of Parliament Act 2022 restored prime ministerial discretion.
2011 年之前，首相可以选择选举日期，利用解散议会的威胁来约束议员。2011 年固定任期议会法废除了这一权力，但 2022 年解散和召集议会法恢复了首相的自由裁量权。
The ability to call an early election can reinforce executive dominance, because rebellious MPs fear losing their seats. Conversely, an unexpected election can also weaken the government if the public punishes a power grab, as seen in 2017.
提前举行选举的能力可以强化行政主导权，因为反叛的议员害怕失去席位。相反，一次意外的选举也可能削弱政府，如果公众惩罚权力争夺，如 2017 年所见。
10. External Constraints and Judicial Review | 外部约束与司法审查
The executive’s dominance over Parliament can also be limited by external legal authorities. Judicial review allows courts to check whether ministers have acted beyond their legal powers, although courts cannot strike down primary legislation.
行政机构对议会的支配也可能受到外部法律权威的限制。司法审查允许法院审查大臣是否超越了法定权力，尽管法院不能废除初级立法。
The Human Rights Act 1998 and, previously, EU law imposed additional constraints on executive action and required Parliament to consider rights compatibility. These external standards can reduce the effectiveness of executive attempts to simply push legislation through.
1998 年人权法以及此前的欧盟法律对行政行为施加了额外限制，并要求议会考虑权利兼容性。这些外部标准可以降低行政机构强行通过立法的效果。
11. Evaluating Effectiveness: When Dominance Succeeds and When It Fails | 评估有效性：主导权何时成功与失败
Overall, the executive is highly effective at exercising dominance over Parliament when it has a disciplined majority, strong party unity, and a divided opposition. In such conditions, it can pass most of its manifesto into law and control the parliamentary agenda almost completely.
总体而言，当行政机构拥有纪律严明的多数席位、强大的党内团结和分裂的反对党时，它对议会行使支配权非常有效。在这种情况下，它可以将大部分竞选纲领变成法律，并几乎完全控制议会日程。
However, effectiveness declines sharply when the majority is small, the governing party is factionalised, the Lords is assertive, or external legal constraints are strong. In these situations, Parliament can amend, delay, or defeat key government measures, showing that executive dominance is conditional rather than absolute.
然而，当多数席位微弱、执政党内部派系化、上议院表现强硬或外部法律约束强大时，有效性急剧下降。在这些情况下，议会可以修改、拖延或否决关键的政府措施，表明行政主导权是有条件的，而非绝对的。
12. Conclusion: A Qualified Dominance | 结论：有条件的支配
The UK executive has formidable structural advantages in its relationship with Parliament, derived from majority
