He and his wife Sheila had seven children,[5] one of whom, also Aindrias Ó Caoimh, was, like his father, appointed a member of the European Court of Justice, in 2004.

Ó Caoimh died at his home in Ranelagh in Dublin, and is buried in Glasnevin Cemetery.

[8] The case concerned the detention without trial of a suspected member of the IRA who claimed that Ireland had breached Articles 5, 6 and 7 of the European Convention of Human Rights that provide rights to liberty and security, fair trial and the principle of ‘no punishment without law’.

[9] The court found in favour of the Irish Government that no violation of the European Convention on Human Rights had taken place.

[10] In September 1970, Ó Caoimh withdrew from the Arms Trial, with the result that the case had to be re-heard after six days of evidence had already been given.
