McQuillan, McGuigan and McKenna, Re Application for Judicial Review

Factual and Procedural Background

These conjoined appeals arise from two sets of legacy cases originating in Northern Ireland during 1971-72:

• The “Smyth” matter – Plaintiff, the sister of a woman fatally shot in June 1972, sought judicial review of the failure by Company A (the regional police service) to carry out a prompt, independent and effective investigation into the death. Previous inquiries by Company B (the former police force) in the 1970s and a 2006-08 review unit were said to be inadequate and to overlook possible military involvement.
• The “Hooded Men” matter – Two applicants (one a surviving detainee, the other the daughter of a deceased detainee) challenged Company A’s October 2014 decision that no further investigation was warranted into allegations that senior Government figures authorised the use of the “five interrogation techniques” (wall-standing, hooding, white-noise, sleep-deprivation, and food-and-drink deprivation) on fourteen internees in August 1971. The techniques had been condemned in earlier domestic and Strasbourg proceedings, but no individual had ever been prosecuted.

Both sets of proceedings were dismissed at first instance in part; the Court of Appeal (Northern Ireland) later allowed the Smyth appeal and, in the Hooded Men case, quashed Company A’s 2014 decision while rejecting other grounds. The present judgment is that of the United Kingdom Supreme Court on appeals by Company A, the Secretary of State and the Department of Justice.

Legal Issues Presented

1. Whether, under the Human Rights Act 1998 (HRA), an investigative duty derived from Articles 2 or 3 of the European Convention on Human Rights (ECHR) can apply to deaths or ill-treatment that occurred decades before 2 October 2000 (the HRA “critical date”).
2. What standard of independence is required of Company A when it investigates conflict-era cases, and whether its Legacy Investigation Branch (LIB) meets that standard.
3. Whether Company A’s decision of 17 October 2014 to close inquiries into alleged ministerial authorisation of the “five techniques” was irrational and should be quashed.
4. Whether parallel duties arise at common law or under section 32 of the Police (Northern Ireland) Act 2000.
5. Whether any legitimate expectation of an independent investigation was created by statements made on 3 July 2014 to The Committee.

Arguments of the Parties

Plaintiffs’ Arguments

• The ECHR investigative obligation revives when new, “Brecknell-type” evidence emerges; the military logs (Smyth) and National Archive papers (Hooded Men) satisfy that threshold.
• The LIB lacks institutional and practical independence because many personnel previously served with Company B and because intelligence vetting, resourcing and governance arrangements are deficient.
• Section 32 of the 2000 Act and earlier public statements created enforceable expectations of an independent, Article 2/3-compliant investigation.
• The 17 October 2014 closure decision was based on a narrow, biased desk-review and was therefore irrational.

Defendants’ Arguments

• The HRA is non-retrospective; a “genuine connection” between pre-2000 events and the critical date is absent, hence no domestic Article 2/3 duty arises.
• Company A is institutionally distinct from Company B; any remaining concerns can be addressed during, not before, an investigation.
• No clear, unambiguous assurance capable of giving rise to a legitimate expectation was given; section 32 imports no Article 2/3-level duty of independence.
• The 2014 review reasonably concluded that new material did not justify further action.

Court's Reasoning and Analysis

Temporal scope of the HRA. Adopting Silih and Janowiec by analogy, the Court ruled that the “critical date” for domestic purposes is 2 October 2000. Events 28–29 years earlier therefore fail the “genuine connection” test; only an extraordinary “Convention values” situation could revive the duty.

Brecknell revival. For the Smyth case, revival cannot operate because neither temporal test is met. In the Hooded Men case, the new archive material was not “weighty and compelling” enough to require a fresh investigation; Ireland v UK (revision judgment, 2018) confirmed most facts were already known.

Independence of Company A. The Court distinguished between (a) institutional/hierarchical connection (satisfied: Company A is structurally separate from Company B and the military) and (b) practical independence (assessed case-by-case). Relying on Tunç, it held:

• Normally courts should await completion of an inquiry before ruling on practical independence, unless proposed arrangements obviously cannot satisfy Article 2/3.
• In the Smyth matter, Company A had not explained investigative safeguards to the family despite past investigative failings; this compromised effectiveness, justifying the Court of Appeal’s intervention.
• No such defect was shown in the Hooded Men proceedings; criticisms of LIB staffing and procedures could be addressed during any future inquiry.

Common-law and statutory duties. Previous authority (McKerr; Keyu) forecloses a free-standing common-law investigative obligation, and section 32 of the 2000 Act does not import an Article 2/3-level independence duty.

Legitimate expectation. The Chief Constable’s July 2014 statement merely restated existing statutory functions and lacked the “clear, unambiguous and unqualified” language needed to found a procedural legitimate expectation.

Irrationality of the 17 Oct 2014 decision. Company A’s closure of the Hooded Men file relied on a narrowly-focused internal report that equated “torture” solely with the use of that term in documents and contained partisan assumptions. This misdirected approach rendered the decision irrational and it was properly quashed.

Holding and Implications

Holding: The Supreme Court ALLOWED IN PART the appeals. It:

• Set aside findings that Company A was legally obliged under Article 2/3 (via the HRA) to investigate the 1971-72 events.
• Confirmed that no common-law or section 32 duty of equivalent scope exists.
• Rejected claims of a procedurally enforceable legitimate expectation.
• Upheld the quashing of Company A’s 17 October 2014 decision, requiring a fresh, rational consideration of whether to investigate the Hooded Men allegations.

Implications: (1) The temporal “genuine connection” test now definitively uses 2 October 2000 as the HRA critical date, sharply limiting domestic legacy-litigation. (2) Investigative independence challenges should focus on concrete defects, not mere perception, and will usually be premature until an inquiry ends. (3) Police forces must, however, give bereaved families sufficient information about proposed investigative structures where earlier inquiries were deficient. (4) Legacy investigators must avoid partisan reasoning; otherwise their closure decisions remain vulnerable to judicial review even absent an Article 2/3 duty.
