From 1962 to 1965, O'Quigley was junior counsel, initially instructed by Richie Ryan,[5] and later under Seán MacBride, on the legal team of plaintiff Gladys Ryan in Ryan v Attorney General, a water fluoridation controversy case wherein the Supreme Court found the Constitution of Ireland safeguarded the unenumerated right to bodily integrity.[6] After the 1965 general election O'Quigley was elected to the 11th Seanad, this time from the Cultural and Educational Panel.[3] He became leader of the Fine Gael group in the Seanad.[3] He was ill for some time before his death,[3] and died in Lourdes.[7]
