parliamentary sovereignty

Dicey (1885)

Parliament can make or unmake any law, no body can override it, and no Parliament can bind its successors — the orthodox baseline of parliamentary sovereignty.

Wade [1955] CLJ 172

Parliamentary sovereignty is an "ultimate political fact" rooted in the 1688 settlement, not an ordinary legal rule, so it cannot be altered by statute (continuing sovereignty); he later called Factortame a "true revolution" in the rule of recognition.

Laws [1995] PL 72

A functional democracy requires a higher-order common law protecting fundamental rights that even Parliament cannot override; the UK sits at an intermediate stage between parliamentary and constitutional supremacy.

Allan, Sovereignty of Law (2013)

Parliamentary sovereignty is already legally conditioned by the rule of law — courts protect fundamental rights by recognising implicit limits on legislative supremacy through normative interpretation, not bare empirical obedience to Parliament.

Ekins (2017) 133 LQR 582

The ECA, HRA, and devolution statutes do not legally constrain Parliament — they are voluntary political choices — and parliamentary sovereignty has never been lost; judicial expansionism is the real constitutional threat.

Goldsworthy [2023] PL 126

Parliamentary sovereignty remains a fundamental element of the constitution confirmed by the Miller cases; reports of its death are premature, though Parliament should not provoke the courts on ouster clauses.

Ellen Street Estates [1934]

Government paid less compensation under a later Housing Act than the earlier Acquisition of Land Act 1919 (not expressly repealed) provided — court upheld implied repeal: a later inconsistent Act automatically prevails, Parliament cannot bind successors as to form (Maugham LJ).

Pickin [1974]

Landowner claimed BRB had misled Parliament in a private Act's preamble to deprive him of land — courts cannot look behind an enacted statute or investigate Parliament's internal procedures even where fraud is alleged (Lord Reid).

Thoburn [2003]

EU-derived delegated legislation preventing pounds from being primary measure unit despite the 1985 W+M Act permitting imperial measures — Laws LJ introduced constitutional statutes (including the ECA 1972) which cannot be impliedly repealed, only expressly, creating a judicial hierarchy of legislation.

Jackson [2006]

Claimants argued the Parliament Act 1949 (and Hunting Act 2004 passed under it) were invalid delegated legislation — Lords upheld the 1949 Act; Lords Steyn and Hope (obiter) suggested sovereignty is no longer absolute and courts might resist legislation abolishing judicial review or democracy itself.

HS2 [2014]

Challenge to HS2 hybrid bill procedure on EU environmental law grounds — no conflict found as EU law did not require scrutiny of Parliament's internal processes; Lords Neuberger and Mance (obiter) suggested Article 9 Bill of Rights takes priority over the ECA where two constitutional statutes genuinely conflict, implying a hierarchy within constitutional statutes.

Miller [2018]

Government sought to trigger Article 50 by prerogative — majority held only Parliament can authorise removal of domestic rights created by the ECA 1972, strongly reaffirming parliamentary sovereignty; Lord Reed (dissent) said prerogative withdrawal would not frustrate Parliament's original intent.

Privacy International [2020]

RIPA 2000 ouster clause purported to exclude judicial review of the Investigatory Powers Tribunal — court held the clause too unclear to oust supervisory jurisdiction; Lord Carnwath said courts determine the limits of all ouster clauses; Lord Sumption (dissent) said the clause was valid as the IPT was itself a judicial body.

Factortame (No 1 & 2) [1990–91]

Merchant Shipping Act 1988 nationality requirements for fishing vessels conflicted with EU law — House of Lords disapplied the Act following ECJ ruling, Lord Bridge describing the ECA 1972 as a voluntary self-imposed limitation on sovereignty; Wade called this a constitutional revolution in the rule of recognition.

Anisminic [1969]

FCC wrongly interpreted "successors in title" to deny Anisminic compensation; FCA 1950 ouster clause purported to protect its "determinations" — Lords held an error of law made the decision a nullity, not a "determination" at all, so the ouster clause could not bite; establishes the strong presumption against excluding judicial review.

Jennings (manner and form theory)

Parliament can lay down binding conditions about how legislation is enacted (procedural/contingent entrenchment) but cannot bind successors as to the content of laws — sovereignty is a legal, not merely political, concept so Parliament can alter the rule of recognition procedurally. Lord Steyn in Jackson (obiter) appeared to endorse this, suggesting Parliament could require a two-thirds majority for certain legislation.

Hart (rule of recognition)

Parliamentary sovereignty rests on an underlying "rule of recognition" — the rule that tells everyone, including courts, what to recognise as law — which emerged from the Glorious Revolution political settlement and is accepted as a social fact by officials and courts rather than deriving from any statute.

Elliott and Thomas

The emerging modern orthodoxy is that Parliament's capacity to legislate is a legal, not purely political, phenomenon — the width of Parliament's power is determined by constitutional law and can change if, and only if, the relevant constitutional law changes.

Varuhas, "The Principle of Legality"

The principle of legality requires clear statutory words before courts will permit Parliament to oust basic common-law norms; Varuhas distinguishes three definitions — classic (express words required), augmented (express words insufficient for disproportionate interference), and proactive (courts construe statutes to minimise intrusion) — arguing the courts' expansion of the proactive version risks collapsing the distinction between the scope and exercise of power.

Barber

After Factortame, the old rule of parliamentary sovereignty ceased to be part of the UK constitution — before it, every statute was born wholly effective; after it, some statutes were born with limited effect. He also argues the uncodified constitution has "constructive ambiguity" because no state body knows the full extent of its powers, though Miller II suggests this ambiguity can no longer be relied upon.

Griffith (political constitutionalism)

Advocates political constitutionalism — conventions, parliamentary scrutiny, and general elections provide sufficient accountability without judicial intervention — as courts lack democratic legitimacy; critics argue Miller II demonstrates political incentives alone cannot prevent executive overreach.

Elliott (rule of law in uncodified constitution)

The rule of law plays a more significant role in an uncodified constitution as it enables judges to declare executive decisions unlawful even without a strike-down power; Privacy International and Anisminic show courts using the presumption against legislating contrary to the rule of law to reconcile parliamentary sovereignty with judicial review.

R (Cart) v Upper Tribunal [2012] 1 AC 663

Government argued Upper Tribunal's unappealable decisions were entirely immune from judicial review under the 2007 Act — Lady Hale held clear words would be needed to oust review entirely and none were present; court adopted a proportionate middle course allowing judicial review only on second-tier appeals criteria, balancing the rule of law against finality.

Re Allister's Application [2023] UKSC 5

Appellants argued the Northern Ireland Protocol breached the Acts of Union 1800 (a constitutional statute) and could not be overridden without express repeal — Supreme Court held Parliament had expressly modified the Act of Union via the EU (Withdrawal) Act 2018, confirming that constitutional statutes are only protected from implied repeal and can still be expressly amended or repealed by clear parliamentary will.

R (LA Albania) v Upper Tribunal [2024] (permission stage)

Applicant challenged a statutory partial ouster clause (s.11A) excluding judicial review of Upper Tribunal refusals of permission to appeal — UKSC refused permission, holding Parliament had clearly expressed its intent to exclude supervisory jurisdiction in the absence of a qualifying exception, suggesting partial ouster clauses are acceptable if Parliament's intent is sufficiently clear and no access-to-justice principle is violated.

R (Evans) v Attorney General [2015]

Attorney General used s.53 FOIA veto to override a court order requiring disclosure of Prince Charles's correspondence, without any change in material facts — Lord Neuberger held courts' decisions are binding and the executive cannot set them aside on mere disagreement; applying the principle of legality, Parliament would need express words to authorise such a veto, giving s.53 a very narrow application. Lord Wilson dissented, arguing the court was being overly interpretive and endangering parliamentary sovereignty.

R (Unison) v Lord Chancellor [2017]

Lord Chancellor imposed fees on employment tribunal claimants, leading to a sharp fall in claims — Lord Reed held the constitutional right of access to justice is a fundamental common-law principle and fees preventing effective access are unlawful; under the principle of legality, Parliament must use express words to authorise such an intrusion, and the enabling statute could not be read to authorise fees at the level set.
