The funeral has taken place in Dublin of Supreme Court Judge Adrian Hardiman.

Mr Justice Hardiman, who was 64, died suddenly at his home in the early hours of Monday morning.

President Michael D Higgins and his wife Sabina along with the Attorney General Máire Whelan, Chief Justice Ms Justice Susan Denham and many serving and retired members of the judiciary attended the funeral mass in Ranelagh this morning.

Taoiseach Enda Kenny was represented by his Aide-de-camp.

Judges of the Supreme Court, Court of Appeal, High Court, Circuit Court and District Court were present. 

18 retired judges also attended along with judges from Northern Ireland, courts service officials and many barristers and solicitors.

Among the mourners were former TDs, Pat Rabbitte, Nora Owen, Mary Harney and Lucinda Creighton.

The eulogy was given by Senior Counsel Michael McDowell who described his best friend as a remarkable man and his passing as an enormous and painful loss for his family and many friends.

Mr McDowell said Mr Justice Hardiman was someone who excelled in his many different personae - as a husband, father, grandfather and brother.

He said he also excelled as a historian, author, advocate, jurist, judge, public speaker and loyal friend.

Mr McDowell said he had known Adrian Hardiman since they were schoolboys.

He said his friend's vision of the Constitution was as a contract between the individual and the State where the State should be the servant and not the master of the people.

He said it was a good thing that the Supreme Court had a balance of people on it spanning those whose priority it was to make the system work and those like Mr Justice Hardiman whose priority it was to make sure the system did not grind down the individual.

Mr McDowell referred to Mr Justice Hardiman's love of history and of the Irish language.

He also said that while he may have crossed swords with many people in court, he never took courtroom advocacy to the point of personal animosity.

Mourners also heard that he was a devoted grandfather and would sometimes call into see one of his grandchildren, simply to watch him sleep.

Chief Celebrant Fr Myles O'Reilly said Mr Justice Hardiman was a proud and patriotic Irishman with a voracious appetite for knowledge.

Mr Justice Hardiman is survived by his wife, retired Circuit Court judge, Yvonne Murphy, his three sons, Eoin, Hugh and Daniel, as well as his brother, Fergal, his sister-in-law, and three grandchildren.
