Justice Jimmy Blacklock, a conservative ally of Gov. Greg Abbott, has been named the new chief justice of the Texas Supreme Court. He replaces Nathan Hecht, the court’s longest serving justice, who stepped down at the end of December due to the mandatory judicial retirement age.

Abbott appointed his general counsel, James P. Sullivan, to take the seat vacated by Blacklock’s promotion.

“The Supreme Court of Texas plays a crucial role to shape the future of our great state, and Jimmy Blacklock and James Sullivan will be unwavering guardians of the Texas Constitution serving on our state's highest judicial court,” Abbott said in a statement.

As chief justice, Blacklock will take on a larger role in the administration of the court. During his tenure, Hecht helped reform the rules of civil procedure and was a fierce advocate for legal aid and other programs to help low-income Texans access the justice system. But, as he told The Texas Tribune in December, when it comes to rulings, “the chief is just one voice of nine.”

Adding Sullivan to the court will further secure the court’s conservative stronghold. While Hecht came up in an era when state courts were less politically relevant, Blacklock and Sullivan are both young proteges of an increasingly active conservative legal movement.

Blacklock attended Yale Law School and clerked on the 5th U.S. Circuit Court of Appeals, and after a stint in private practice, he joined the Texas Office of the Attorney General under Abbott. He helped lead Texas’ aggressive litigation strategy against the Obama administration, defending the state’s restrictive abortion and voter identification laws, gay marriage restrictions and crusade against the Affordable Care Act.

When Abbott became governor, Blacklock became his general counsel. Abbott appointed him to the bench in December 2017, when he was just 38 years old.

The Texas Supreme Court has transformed over the last few decades from a plaintiff-friendly venue dominated by Democrats to the exclusive domain of increasingly conservative Republicans. Abbott, a former justice himself, has played a huge role in this shift, appointing six of the nine current justices, including Sullivan.

Sullivan graduated from Harvard Law School and clerked for the D.C. Circuit Court of Appeals. He spent four years as Texas assistant solicitor general during Abbott’s tenure as attorney general, and in 2018, became Abbott’s deputy general counsel. In 2021, he became the governor’s general counsel.

“As General Counsel for the Office of the Governor, James Sullivan has provided superior legal advice and rendered opinions on some of the most consequential legal issues in Texas,” Abbott said in a statement. “He has the integrity, temperament, and experience Texas needs as a Texas Supreme Court Justice.”

It’s now seen as one of the most conservative high courts in the country, issuing consequential rulings on abortion, COVID restrictions, health care for trans minors and local control in just the last few years. While Democrats have tried to pin these often unpopular rulings on the justices during election years, incumbents tend to easily win reelection in these relatively low-awareness down-ballot races.

Blacklock defeated Harris County District Judge DaSean Jones in November by more than 16 points. In a statement Monday, he thanked Hecht for his “extraordinary legacy of service.”

“The Supreme Court of Texas belongs to the People of Texas, not to the judges or the lawyers,” he said. “Our job at the Court is to apply the law fairly and impartially to every case that comes before us. My colleagues and I are committed to defending the rule of law and to preserving our Texas and United States Constitutions.”
