The claimants challenged the lawfulness of the policy adopted by the Senior Coroner for Inner North London, Ms Mary Hassell, that no death will be prioritised in any way over any other because of the religion of the deceased or family, either by the coroner's officers or by coroners – described variously by Ms Hassell as a ‘cab rank rule’ and ‘an equality protocol’ – on the grounds that it breached Article 9 of the European Convention on Human Rights (ECHR) (thought, conscience and religion) and Article 14 (discrimination), that it was indirect discrimination contrary to section 19 of the Equality Act 2010 and that it breached the public sector equality duty (PSED) in section 149 of that Act. The Chief Coroner, as an interested party, submitted that, as a matter of public law and quite apart from the Human Rights Act 1998, the policy was unlawful because it fettered Ms Hassell's discretion and was irrational. Ms Hassell's particular concern was that the Jewish families represented before the court were being prioritised over other families by her coroner's officers and she wished to stop the practice because she argued that what causes most distress for all families is a delay in decision-making and notification of that decision. She maintained that her policy took account of Articles 8, 9 and 14 ECHR and the relevant sections of the Equality Act.

The court concluded that the coroner's power in the present case was akin to a power derived from statute, that the principle against fettering a discretion therefore applied and that the policy breached that principle. As to the issue of irrationality, Ms Hassell accepted that cases such as deaths that were the subject of homicide investigations and organ donations had to be given priority, so the policy was not a strict cab rank rule because not every case was dealt with in chronological order, nor was it capable of rational justification. As to Article 9 ECHR and the Equality Act 2010, Article 9 required not that there should be any favouritism, whether in favour of religious belief in general or in favour of any particular religious faith, but that there should be a fair balance struck between the rights and interests of different people in society. Ms Hassell's policy failed to do that. Moreover, as a matter of domestic law, prioritisation of some deaths for religious reasons would not be unlawful; on the contrary, it would be consistent with section 158 of the Equality Act 2010. The fact that other coroners did not operate the same strict policy did not seem to cause undue difficulties, nor could the policy be justified by an argument of limited resources. It therefore violated the principle of equal treatment in Article 14 ECHR and also discriminated against Jews and Muslims, though it was not in breach of the PSED. The court held as follows:

The claim succeeded on all grounds except that based on the PSED. The court granted a declaration that the current policy was unlawful and made a quashing order setting it aside. [Frank Cranmer]
