## Judicial career

O'Connor was appointed to the High Court in October 2015. He has heard cases involving tax law, extradition, insolvency, injunctions, defamation, personal injuries, and commercial disputes.
O’Connor heard a case in 2015 relating to a truck driver who was alleged by Greek authorities to have had contraband cigarettes among his consignment of olive oil when his truck was inspected in 2002. The truck driver was told over 10 years later that he owed €1.5 million to the Greek authorities which the Irish revenue was obliged to collect under EU law. O’Connor referred the case to the European Court of Justice under the preliminary reference procedure. The ECJ in 2018 answered the questions posed and, in May 2018, O’Connor granted a declaration that the Irish Revenue could not fulfil the request of the Greek authorities to recover the sum sought.
In 2018, he found for Graham Dwyer, the man convicted of the murder of Elaine O'Hara, ruling that the legislation relied on to secure his conviction was contrary to EU law. The decision was appealed to the Supreme Court of Ireland, which in turn made a reference to the European Court of Justice.
He is a member of the board of the Courts Service.
In July 2020, he was appointed as a member of a three-judge tribunal into the CervicalCheck cancer scandal with chairperson Ann Power and retired judge Brian McGovern. O'Connor continued hearing cases in the High Court during his time on the tribunal.

In December 2022, he awarded €365,000 to a factory worker who had sustained a back injury.
