Anthony Hayden

Sir Anthony Paul Hayden (born 24 June 1961), styled The Hon. Mr Justice Hayden, is a judge of the High Court of England and Wales and former barrister appointed to the High Court.

He was called to the bar at Middle Temple in 1987 and was appointed a Queen's Counsel (QC) in 2002. On 31 July 2013, he was appointed a judge of the High Court of Justice (Family Division) and invested with the customary knighthood in 2014.

In 2018 he presided the Alfie Evans case over the legal challenge by the parents of Alfie Evans against Alder Hey Children's Hospital.

On 1 April 2019, Hayden sought further evidence for a case brought to the Court of Protection in which a man was to be barred from having sex with his wife as the woman suffers from learning difficulties whose apparently deteriorating condition may impair her ability to give sexual consent. During a preliminary hearing, he was reported to have stated "I cannot think of any more obviously fundamental human right than the right of a man to have sex with his wife – and the right of the state to monitor that, … I think he is entitled to have it properly argued."
