In R (Grice) v HM Senior Coroner of Brighton and Hove [2020] EWHC 3581, the High Court has summarised the scope of the requirements under Article 2 of the European Convention of Human Rights (ECHR) for an effective investigation into alleged failures of the police to protect life. The question arose where a coroner had refused to re-open the inquest into the murder of a woman by her former partner after the police had mishandled her complaints of stalking. While the criminal trial by itself had not satisfied the Article 2 investigative obligation, it had been met by the combination of the criminal trial and the four subsequent investigations of police conduct.
