Harriet O'Neill

O'Neill was first elected to the Texas Supreme Court in 1998. Previously, O'Neill had been a justice of the Fourteenth Court of Appeals of Texas since 1995, when then-Governor George W. Bush appointed her. Prior to that, O'Neill had been a trial judge for the 152nd District Court, located in Houston, to which she was elected in 1992.

O'Neill completed her undergraduate studies at Converse College and she received her J.D. from the University of South Carolina School of Law in 1982. Prior to joining the bench, O'Neill was in private practice in Houston. She practiced law with the firms of Porter & Clements, Morris & Campbell, and then opened her own practice. Throughout those ten years, O'Neill practiced mostly complex business and commercial litigation.

Harriet Smith O'Neill (born April 20, 1957) is a retired associate justice of the Supreme Court of Texas. A Republican, O'Neill represented Place 3 of the nine positions on the court. O'Neill's term was to expire on December 31, 2010, and she declined to seek re-election to a third full six-year term. In the April 13 Republican runoff election, Judge Debra Lehrmann, a family court jurist from Fort Worth, defeated Rick Green, a former state legislator and Constitutional speaker from Dripping Springs. O'Neill subsequently decided to leave the court early and vacated the seat on June 20, 2010. Lehrmann was appointed by Governor Rick Perry to fill out O'Neill's term.
