Almost 6 years after the events, the Supreme Court gave judgment in the case of
Hicks and others v Commissioner of Police for the Metropolis [2017] UKSC 9. The case arose as a result of arrests made on the day of the
Royal Wedding on 29th April 2011. The arrests were based on prevention of public disorder.
The Supreme Court was concerned with
Article 5 of the European Convention on Human Rights (ECHR). Article 5 specifies the situations in which an individual may be deprived of liberty - see Article 5(1) and also note Article 5(3). In particular, Article 5(1)(c) states:
"the lawful arrest or detention of a person effected for the purpose of bringing him before the competent legal authority on reasonable suspicion of having committed an offence or when it is reasonably considered necessary to prevent his committing an offence or fleeing after having done so;"
For the purposes of the European Convention, a breach of the peace is considered to be an "offence" even though it is not classified as an offence under English law.
