📚 How the constitution has changed since 1997 | 1997年以来英国宪法的演变
The UK constitution has undergone profound and far-reaching change since 1997, with the election of the first Blair government marking a decisive break from the traditional evolutionary model. New Labour’s programme of constitutional modernisation — encompassing devolution, the Human Rights Act, Lords reform, and the creation of a Supreme Court — fundamentally redistributed power away from Westminster. Subsequent events such as the 2011 Fixed-term Parliaments Act, Brexit, and the recent debates over a British Bill of Rights have continued to reshape the constitutional landscape. While the UK still lacks a single codified constitutional document, these reforms have cumulatively transformed the location and exercise of sovereignty, the relationship between the individual and the state, and the mechanisms of executive accountability.
自1997年布莱尔政府上台以来，英国宪法经历了深刻而广泛的变革，打破了传统的渐进演变模式。新工党的宪法现代化计划——包括权力下放、《人权法案》、上议院改革和最高法院的设立——从根本上分散了威斯敏斯特的权力。此后的《2011年固定任期议会法》、脱欧以及近期关于《英国权利法案》的辩论，继续重塑着宪法格局。尽管英国仍缺乏一部单一的法典化宪法文件，但这些改革累计改变了主权的位置与行使方式、个人与国家之间的关系以及行政问责的机制。
1. Devolution to Scotland, Wales and Northern Ireland | 向苏格兰、威尔士和北爱尔兰的权力下放
The most dramatic constitutional innovation after 1997 was the establishment of devolved legislatures and executives in Scotland, Wales, and Northern Ireland. The Scotland Act 1998 created the Scottish Parliament with primary legislative powers and tax-varying authority, a transfer of significant sovereignty away from Westminster. The Government of Wales Act 1998 established a weaker National Assembly, initially with only secondary legislative competence, though this was later enhanced to full law‑making powers in devolved areas following a 2011 referendum. The Belfast Agreement (Good Friday Agreement) of 1998 led to the Northern Ireland Act 1998, setting up a power‑sharing Assembly and Executive designed to embed cross‑community consent. These settlements entrenched a quasi‑federal structure, creating multiple political arenas that constrain the traditional doctrine of parliamentary sovereignty in practice.
1997年后最引人注目的宪法创新是苏格兰、威尔士和北爱尔兰建立了权力下放的议会和政府。1998年《苏格兰法》设立了拥有基本立法权和调整税率权的苏格兰议会，将相当一部分主权从威斯敏斯特转移出去。1998年《威尔士政府法》建立了权力较弱的国民议会，最初只拥有次级立法权，但在2011年全民公决后其权力被强化为在权力下放领域拥有完整的法律制定权。1998年《贝尔法斯特协议》（耶稣受难日协议）促成了1998年《北爱尔兰法》，建立了以跨社群共识为核心的权力分享议会和行政机构。这些安排固化了准联邦制结构，创造出多个政治舞台，在实践中约束了传统议会主权学说。
2. The Human Rights Act 1998 | 1998年《人权法案》
The Human Rights Act 1998 marked a fundamental shift in the UK’s rights culture by incorporating most of the European Convention on Human Rights (ECHR) directly into domestic law. For the first time, individuals could rely on Convention rights in UK courts, and public authorities were placed under a statutory duty to act compatibly with these rights. The Act’s Section 3 interpretive obligation requires courts to read and give effect to legislation in a way that is compatible with Convention rights ‘so far as it is possible to do so’, while Section 4 allows senior courts to issue a ‘declaration of incompatibility’ if such a reading is impossible. This has not overridden parliamentary sovereignty — Parliament remains free to maintain incompatible legislation — but it has created a robust dialogue between the judiciary and the legislature that has significantly strengthened the protection of individual rights.
1998年《人权法案》将《欧洲人权公约》的绝大部分内容直接纳入国内法，标志着英国权利文化的根本性转变。个人首次可以在英国法院直接依据公约权利提起诉讼，公共机构则负有以符合公约权利的方式行事的法定义务。法案第3条的解释性义务要求法院“在尽可能的范围内”以符合公约权利的方式解读并赋予立法效力；第4条则允许高级法院在无法做出这种解读时发出“不一致声明”。这并未凌驾于议会主权之上——议会仍然可以维持不一致的立法——但它创建了司法机关与立法机关之间强有力的对话机制，显著加强了对个人权利的保护。
3. House of Lords Reform: Removal of Most Hereditary Peers | 上议院改革：废除大多数世袭贵族
The House of Lords Act 1999 transformed the composition of the upper chamber by abolishing the right of all but 92 hereditary peers to sit and vote. This was a radical break with almost 800 years of inherited legislative privilege and was intended as the first stage of a wider reform to make the Lords more democratic and representative. Nonetheless, subsequent attempts to move towards an elected or largely elected second chamber — such as the 2003 white paper and the 2012 House of Lords Reform Bill — all failed due to lack of parliamentary consensus. The chamber today remains wholly appointed, except for the 92 remaining hereditary peers and the Lords Spiritual. The 2005 Constitutional Reform Act also ended the appellate jurisdiction of the House of Lords by creating a separate Supreme Court, removing the anomaly of the Law Lords being both legislators and the nation’s final court of appeal.
1999年《上议院法》通过取消除92名世袭贵族外所有世袭贵族的上院议席与投票权，彻底改变了上院的组成结构。这是与近800年传袭立法特权传统的决裂，并被设想为更广泛改革的初步阶段，旨在使上院更加民主和更具代表性。然而，此后试图走向民选或主要民选的第二院，如2003年白皮书和2012年《上议院改革法案》，均因缺乏议会共识而告失败。如今上院除保留的92名世袭贵族及灵职议员外，全部成员均为任命产生。2005年《宪制改革法》通过创设独立的最高法院，终结了上院的上诉管辖权，从而消除了司法贵族既担任立法者又充任国家终审法院这一宪制异常。
4. The Constitutional Reform Act 2005 and the Supreme Court | 2005年《宪制改革法》与最高法院
The Constitutional Reform Act 2005 introduced major changes to the separation of powers by establishing a statutorily independent Supreme Court, which began operating in 2009. The Act transferred the judicial functions of the Lord Chancellor to the Lord Chief Justice, ended the Lord Chancellor’s role as head of the judiciary, and created the Judicial Appointments Commission to enhance the independence and transparency of the selection process. The creation of the UK Supreme Court physically and institutionally separated the highest court from Parliament, reinforcing the perception of judicial independence and strengthening the judiciary’s confidence to scrutinise government action. The Supreme Court has since delivered highly significant rulings on issues such as the triggering of Article 50 (Miller I, 2017) and the prorogation of Parliament (Miller II, 2019), demonstrating its new role as a key constitutional arbiter.
2005年《宪制改革法》通过建立法定的独立最高法院（于2009年开始运作），对权力分立做出了重大变革。该法将大法官的司法职能转移至首席大法官，结束了大法官作为司法系统首脑的角色，并设立了司法任命委员会，以增强遴选过程的独立性和透明度。联合王国最高法院的建立，将最高审判机关从议会中物理和制度上分离出来，强化了司法独立的观感，并增强了司法机关审查政府行为的信心。最高法院其后在触发《里斯本条约》第50条（2017年米勒第一案）以及议会休会（2019年米勒第二案）等问题上做出了极具影响力的裁决，彰显了其作为关键宪法仲裁者的新角色。
5. The Freedom of Information Act 2000 | 2000年《信息自由法》
The Freedom of Information Act 2000 came fully into force in 2005 and created a general right of access to information held by public authorities. For the first time, citizens could request records from a vast range of public bodies, with an independent Information Commissioner and Tribunal providing oversight and enforcement. The Act has been a powerful tool for accountability, exposing political scandals such as the MPs’ expenses crisis of 2009. However, its impact has been tempered by extensive exemptions (e.g. for policy formulation, national security, and commercial confidentiality) and by ministerial veto powers, which were controversially exercised in 2011 over the release of the Prince of Wales’ ‘black spider’ letters. The Act nonetheless contributed to a more open and transparent governance culture.
2000年《信息自由法》于2005年全面生效，创设了获取公共机构所持信息的普遍权利。公民首次得以从广泛的公共机构处请求查阅档案，并设有独立的信息专员和裁判所进行监督和强制实施。该法成为问责的有力工具，曝光了2009年议员报销丑闻等政治事件。然而，其效力受到了广泛的豁免条款（例如为政策制定、国家安全、商业保密等设置）以及部长否决权的制约；部长否决权在2011年关于查尔斯亲王“黑蜘蛛”信件的公布问题上引起了很大争议。尽管如此，该法仍促进了更为开放透明的治理文化。
6. The Fixed-term Parliaments Act 2011 | 2011年《固定任期议会法》
The Fixed-term Parliaments Act 2011 (FTPA) was a significant constitutional experiment that removed the prime minister’s traditional prerogative power to request a dissolution of Parliament and instead set a fixed five‑year parliamentary term. The Act stipulated that an early general election could be triggered only in two circumstances: if two‑thirds of MPs voted in favour, or if a motion of no confidence passed and no alternative government was formed within 14 days. In practice, the Act proved problematic. In 2019, the government was able to bypass the two‑thirds requirement by passing a one‑line bill for an early election under the guise of a separate statute. The Act was repealed by the Dissolution and Calling of Parliament Act 2022, which restored the prime minister’s prerogative power and signalled a return to flexible, politically convenient election timing. The episode highlights the difficulty of formalising conventions deeply embedded in executive authority.
2011年《固定任期议会法》是一次重大的宪法试验，该法取消了首相当日享有的是否请求解散议会的传统特权，转而将议会固定为五年任期。此法规定，提前大选只能在两种情形下触发：三分之二议员投票赞成，或通过对政府的不信任动议且十四天内无法组成替代政府。在实践中，该法显示出种种弊端。2019年，政府得以通过一个简单的单条法案绕过三分之二多数要求，以独立法令的形式召集提前大选。该法最终被2022年《解散和召集议会法》废止，重建了首相解散议会的特权，标志着回归更为灵活、政治上便利的选举时机。这一事件凸显了将深嵌于行政权力中的宪政惯例予以成文化的困难。
7. Changes to the Judiciary and Judicial Review | 司法系统与司法审查的变革
The period since 1997 has witnessed a significant expansion in the scope and intensity of judicial review. The consolidation of the Supreme Court’s authority, the growth of judicial review of executive decisions concerning human rights, and proceedings under the European Union legal framework all contributed to a more assertive judiciary. The Miller cases of 2017 and 2019 underlined the courts’ willingness to adjudicate major constitutional questions, while the Belhaj and Rahmatullah litigation illustrated the courts’ scrutiny of foreign affairs and national security actions. The expansion of judicial power has generated a political backlash, with some ministers accusing the judiciary of overreach. The Independent Review of Administrative Law (2021) and the subsequent Judicial Review and Courts Act 2022 have introduced restrictions on certain types of judicial review remedies, representing a reassertion of executive and legislative supremacy in response to the post‑1997 judicialisation of politics.
1997年以来，司法审查的范围和强度显著扩展。最高法院权威的确立、与人权相关的行政决定司法审查的增多，以及在欧盟法律框架下进行的诉讼，共同促成了一个更为自信的司法系统。2017年和2019年的米勒案凸显了法院裁决重大宪法问题的意愿，而贝尔哈吉案和拉赫马图拉案等诉讼则展示了法院对外交事务与国家安全行为进行审查的能力。司法权的扩张引发了政治反弹，一些大臣指责司法越权。2021年行政法独立审查及其后出台的2022年《司法审查和法院法》对某些类型的司法审查救济措施引入了限制，这是对1997年后政治司法化趋势的回击，重申了行政权与立法权的至上地位。
8. Brexit and Constitutional Destabilisation | 脱欧与宪法震荡
The 2016 EU referendum and the subsequent withdrawal process caused exceptional strains on the UK constitution. Referendums had previously been confined to specific issues and were constitutionally consultative, but the Brexit referendum was treated by many as a binding mandate, creating a clash between direct democracy and representative parliamentary sovereignty. The Article 50 process exposed deep uncertainties about the prerogative power, leading to the Miller I Supreme Court ruling that parliamentary approval was needed. The subsequent parliamentary deadlock over the Withdrawal Agreement, the prorogation of Parliament in 2019, and the Miller II decision which declared the prorogation unlawful all demonstrated the capacity of the constitution to stretch and adapt under pressure — but also its vulnerability when conventions are pushed beyond consensus. Brexit also necessitated the wholesale repeal and amendment of EU‑derived law, testing the territorial constitution in relation to the devolved governments and the Northern Ireland Protocol.
2016年脱欧公投及其后的退出过程给英国宪法造成了特殊压力。此前公投往往限于特定议题且具有宪法上的咨询性质，但脱欧公投却被许多人视为具有约束力的授权，从而造成直接民主与代议制议会主权之间的冲突。启动第50条的过程暴露了特权权力的深层不确定性，导致最高法院米勒第一案裁定须经议会批准。此后议会在脱欧协议上的僵局、2019年的议会休会，以及米勒第二案宣布该休会为非法，都展示了宪法能够在压力下延伸和调适的能力，但也暴露了当宪政惯例被推向合意边界之外时的脆弱性。脱欧还迫使对源自欧盟的法律进行全盘废除和修订，在与权力下放政府以及北爱尔兰议定书相关方面检验了国家的地域性宪法安排。
9. Devolution in England: Combined Authorities and EVEL | 英格兰的权力下放：联合管理局与英格兰议员立法表决
While devolution to Scotland, Wales, and Northern Ireland was territorial and legislative, devolution within England has been largely administrative and executive. The creation of combined authorities, introduced through the Cities and Local Government Devolution Act 2016, allowed groups of local authorities to receive devolved powers over transport, skills, and economic development, overseen by directly elected ‘metro mayors’. This has produced a fragmented but evolving landscape of city‑region governance. A parallel innovation was ‘English Votes for English Laws’ (EVEL), introduced in 2015, which gave English (or English and Welsh) MPs a veto on legislation affecting only England. EVEL was criticised for creating two classes of MPs and was suspended in 2021, signalling that attempts to solve the ‘West Lothian Question’ through procedural means had failed. The asymmetrical pattern of devolution remains an unresolved tension in the post‑1997 constitution.
虽然向苏格兰、威尔士和北爱尔兰的权力下放带有地域性和立法性，英格兰内部的权力下放则主要停留在行政与执行层面。《2016年城市与地方政府权力下放法》引入的联合管理局模式，允许各地地方当局群体在交通、技能和经济发展等领域获得下放权力，并由直选产生“市级市长”负责监督。这创造了一个碎片化却不断演进的城市区域治理格局。与之一同推进的创新是2015年引入的“英格兰议员为英格兰法律表决”程序，该程序赋予英格兰（或英格兰与威尔士）议员对仅影响英格兰的立法以否决权。EVEL因制造出两类议员而受到批评，并于2021年被暂停执行，表明试图以程序手段解决“西洛锡安问题”的努力已告失败。不对称的权力下放格局仍是1997年后宪法中一个未解的张力。
10. The British Bill of Rights Debate and Recent Developments | 《英国权利法案》争论与近期发展
Since 2022, a significant shift in rights protection has been signalled by the government’s proposed Bill of Rights Bill, which would repeal and replace the Human Rights Act 1998. The proposal seeks to recalibrate the balance between the domestic courts and the Strasbourg court, introduce a ‘permission stage’ for human rights claims, and limit the remedies available to claimants. While the Bill did not complete its passage, the underlying political ambition to assert a distinct British rights framework has persisted. More broadly, the Elections Act 2022 introduced mandatory voter identification and changed the oversight mechanisms for the Electoral Commission, while the Northern Ireland Troubles (Legacy and Reconciliation) Act 2023 raised profound issues about the rule of law and the ECHR. These recent developments demonstrate that the post‑1997 period of constitutional flux is far from over.
自2022年起，政府提出的《权利法案》（Bill of Rights Bill）表明权利保护方面将发生重大转变，该法将废除并取代1998年《人权法案》。提案试图重新校正国内法院与位于斯特拉斯堡的欧洲人权法院之间的平衡，引入人权诉讼的“许可阶段”，并限制原告可获得的救济措施。虽然该法案未能完成立法过程，但其背后构建独特的英国权利框架的政治意图依然持续。更广泛地看，2022年《选举法》引入强制性选民身份证明并变更了选举委员会的监督机制，而2023年《北爱尔兰麻烦（遗产与和解）法》则引发了关于法治和《欧洲人权公约》的深刻问题。这些近期发展表明，1997年后宪法变动的时期远未终结。
11. The Erosion of Royal Prerogative and Parliamentary Sovereignty | 王室特权与议会主权的消蚀
One central theme running through the changes since 1997 has been the erosion of the traditional royal prerogative powers, now exercised by ministers, and their replacement by statute and judicial oversight. The power to dissolve Parliament, to conduct international relations via treaty-making, to appoint judges, and to regulate the civil service have all been brought under statutory frameworks. The Constitutional Reform and Governance Act 2010 gave Parliament a statutory role in treaty ratification, while the Supreme Court’s decision in Miller I confirmed that prerogative cannot be used to change domestic law or frustrate statutes. These developments indicate a clear trajectory towards a more legal, as opposed to conventional, constitution — albeit one that remains uncodified and rests on the traditional keystone of parliamentary sovereignty, which itself has been recast by practical limitations arising from devolution, EU membership, and human rights law.
贯穿1997年以来变革的一个中心主题是由大臣行使的传统王室特权逐渐消蚀，并被成文法与司法监督所替代。解散议会之权、通过缔结条约处理国际关系之权、任命法官之权以及规管文官系统之权，均已被纳入法定框架。2010年《宪制改革与治理法》赋予议会在条约批准方面的法定角色，而最高法院在米勒第一案中则确认特权不可用于改变国内法或阻碍成文法的施行。这些发展清楚地指向一个更趋向于法律而非惯例统治的宪法——尽管这部宪法仍未法典化，且仍立足于议会主权这一传统基石之上，而这一主权本身也因权力下放、欧盟成员国身份以及人权法律的实践限制而被重塑。
12. Conclusion: A Constitution in Transformation | 结论：仍在转型中的宪法
Since 1997, the UK constitution has undergone an extraordinary period of reform that has transformed governance and rights, establishing new territorial arrangements, redefining the relationship between the executive and the judiciary, and testing the resilience of parliamentary sovereignty. Yet change has often been piecemeal, reactive, and lacking an overarching philosophical coherence. The centrifugal pressures of devolution, the demands of rights jurisprudence, and the seismic shock of Brexit have all pulled the constitution in different directions. As a result, the contemporary UK constitution is best understood not as a stable settlement but as a dynamic and contested process — one in which sovereignty is increasingly shared, conventions are constantly renegotiated, and the absence of a codified document is felt more acutely than at any time in recent history.
自1997年以来，英国宪法经历了非凡的变革期，改变了治理与权利的面貌，创设了新的领土安排，重新界定了行政与司法之间的关系，并检验了议会主权的韧性。然而，这种变革常常是零碎的、反应式的，且缺乏总体上的哲学一致性。权力下放带来的离心压力、权利法学的要求以及脱欧的地震式冲击，正从不同方向撕扯着宪法。因此，最好将当代英国宪法理解为某种动态而备受争议的过程，而非一个稳固的体制。在这个过程中，主权正越来越多地被共享，惯例如今不断被重新协商，而没有一部法典化宪法的缺失感比近代史上任何时候都更为强烈。
