Abbott Names Party-Switching Ex-Lawmaker Shawn Thierry to New Harris County Bench

Former Houston state Rep. Shawn Thierry, who switched from the Democratic to the Republican Party after losing her 2024 primary, has been appointed by Gov. Greg Abbott to lead one of three brand-new civil district courts in Harris County. Thierry will oversee the 515th District Court, with her appointment running through the end of 2028, while fellow appointee Michael Landrum, a 74-year-old judge, takes the bench of the newly created 514th District Court.

A New Court Born From a 2025 Special Session

The 515th District Court, along with the 513th and 514th, was created during the 2025 legislative session, according to the Houston Chronicle. State lawmakers formalized the courts through House Bill 16 during a 2025 special session of the 89th Texas Legislature, which mandated the three new courts take effect September 1, 2026, and directed them to give preference to civil cases, per Texas Legislature Online. Thierry and Landrum are both scheduled to take office on September 1, but the Chronicle's report notes the two will not immediately have their own courtrooms inside the civil courthouse at 201 Caroline Street. Instead, their dockets will be established just days after they take office, and Harris County Justice Administration Department director Sam Peña said the incoming judges will likely have to share a court with others in the meantime.

A Courthouse Under Construction

Harris County plans to build four more courts at the 201 Caroline Street courthouse by 2027, along with space for two additional new courts at 1119 Congress Street, the same Chronicle report states. The nearby Family Law Center Annex at 1115 Congress Street has been slated for demolition but could still be used in the coming months as a stopgap. According to an investment memo, the new-court project is expected to be completed next spring. To comply with the state mandate for six new and relocated courts, Harris County Commissioners approved a Final Investment Memo in April expanding total authorization for the courts expansion project to $54.83 million, according to Harris County records. The Texas Legislature had already ordered the creation of several criminal courts in 2023 to ease a backlog in felony cases caused by Hurricane Harvey and pandemic-related delays.

From Sunnyside Democrat to GOP Appointee

Thierry, a former Texas state representative who served four terms, lost her seat in a lopsided May 28, 2024 Democratic primary runoff, falling to progressive challenger Lauren Ashley Simmons by a 64.6% to 35.4% margin, according to Ballotpedia. Hoodline previously reported on that runoff defeat, which followed a Sunnyside Park campaign event in May 2024 and came after Thierry's high-profile votes backing Republican-led LGBTQ+ restrictions. Her former district, which she represented from 2017 to 2024, was a heavily Democratic, majority-minority Houston district encompassing Sunnyside and Westwood that Joe Biden carried by nearly 80 percentage points in 2020, per the Texas Tribune's reporting cited in the dossier.

Thierry has said she could not support policies promoting sex changes for children and dismantling Title IX protections for women in sports, and she supported a ban on gender-affirming care for minors, according to the Chronicle. She went on to denounce the Democratic Party as having veered too far to the left before formally announcing her switch to the Republican Party. In August 2024, before that formal party switch, she was named director of political strategy for the U.S. wing of Genspect, an organization founded by Irish psychotherapist Stella O'Malley that campaigns against gender-affirming medical treatments for people under 25, according to KSAT.

A Sequence of Abbott Appointments

Abbott's appointment of Thierry to the 515th District Court follows a pattern of executive appointments building her state profile since her primary loss. On January 13, 2025, Abbott appointed her to the Texas Juvenile Justice Board, the governing body responsible for setting administrative rules and policy for state youth corrections, a move Hoodline covered in a prior story on her board role. Thierry holds a law license and previously worked at Texas Southern University as executive director for policy and counsel, and the Chronicle notes she has served on the Texas Juvenile Justice Department board.

The appointment also fits into Gov. Abbott's broader strategy for Harris County. Abbott pledged late last year to deploy significant campaign reserves to flip Harris County back to Republicans and, in his words, “make Harris County dark red,” according to the Texas Tribune. Harris County has been a target for Republicans since November 2018, when Democratic candidates swept all 59 judicial seats on the county ballot, unseating every sitting Republican judge across civil, criminal, family, juvenile, and probate courts — marking the first time in decades Republicans held no elected district judgeships there.

Landrum's Age Ceiling Sets Him Apart

Landrum, the other new appointee, previously served in two other courts, including the 113th District Court, and obtained his law license in 1976. He lost his seat in that same 2018 Democratic sweep and was later appointed by Abbott to the 164th District Court bench in 2020. But unlike Thierry, Landrum cannot seek election to keep his new seat because of age restrictions: under Article V, Section 1-a of the Texas Constitution, state district judges face mandatory retirement at 75, and Landrum is already 74. Texas voters explicitly reaffirmed that limit in November 2023 by defeating Proposition 13, a constitutional amendment that would have raised the mandatory retirement age from 75 to 79 — the only one of 14 proposed amendments Texas voters rejected that year, according to the Texas Tribune. Because of the age cap, Harris County voters will elect the next judicial candidate to fill the 515th District Court seat in 2028, while whoever succeeds Landrum on the 514th will be chosen through a separate process once he reaches the constitutional limit.
