Judge Barbara Hervey has served on Texas’s Court of Criminal Appeals since 2000, winning multiple six-year terms. Before her judicial career, she worked as a Bexar County assistant district attorney for 16 years after graduating from St. Mary’s University School of Law. Her most significant contribution came in 2008 when she established the Texas Criminal Justice Integrity Unit, which tackles wrongful convictions statewide. Her reforms continue to reshape how Texas delivers justice.
Early Life and Education at UNC Greensboro
The foundation of Barbara Hervey’s distinguished legal career was laid at the University of North Carolina at Greensboro, where she earned her bachelor’s degree in 1975.
During her formative years at this respected institution, she developed the analytical thinking and intellectual rigor that would later serve her well in the legal profession. Her time at UNC Greensboro provided her with a strong academic foundation before she pursued her legal education.
After completing her bachelor’s degree, Hervey set her sights on law school, eventually attending St. Mary’s University School of Law in San Antonio. This educational trajectory would ultimately lead her to a multifaceted career that included roles as an assistant criminal district attorney in Bexar County, a private attorney, and later, a judge who would make significant contributions to Texas law.
Law School Years at St. Mary’s University
In 1976, Barbara Hervey arrived at St. Mary’s University School of Law, Texas’s only Catholic law school, long recognized for its diverse and inclusive student body. During her three years in San Antonio, she didn’t just earn her Juris Doctor; she established deep roots in the local legal community that would shape her future career.
After graduating in 1979, Hervey’s relationship with St. Mary’s evolved as she returned to serve as an adjunct professor, sharing her growing expertise with new generations of law students. Her connection to the school strengthened through prestigious memberships in the Texas Bar Foundation and American Law Institute.
These formative years at St. Mary’s University School of Law provided Hervey with more than legal knowledge—they gave her a professional home in San Antonio where her influence on Texas law would continue to grow.
Career as Bexar County Assistant District Attorney
After graduating from St. Mary’s University School of Law, Barbara Hervey commenced a formidable 16-year career as an assistant criminal district attorney in Bexar County. She prosecuted a wide spectrum of criminal cases, from complex felonies to misdemeanors, and honed her deep understanding of Texas criminal law.
Hervey’s time in the DA’s office wasn’t just about securing convictions—it was where she developed the nuanced perspective on criminal justice that would later define her judicial philosophy. Her daily immersion in prosecutorial work equipped her with practical insights few judges possess. The courtroom became her classroom as she mastered the intricacies of criminal procedure and constitutional applications.
This prosecutorial background gave Hervey a foundation that would prove invaluable when she later ascended to the bench.

Destiny called Barbara Hervey to higher service in 2000 when Texas voters elected her to the Court of Criminal Appeals, the state’s highest criminal court. After sixteen years as a Bexar County prosecutor, this San Antonio legal expert would transform her local experience into statewide impact.
Hervey’s judicial journey includes:
- Winning her initial election in 2000, beginning her influential tenure
- Securing three subsequent six-year terms, most recently in 2018
- Defeating Democratic challenger Maria T. (Terri) Jackson with approximately 52.7% of the vote
- Bringing her St. Mary’s University law education to the bench
- Earning recognition for her contributions to Texas’s criminal justice system
Hervey’s evolution from local prosecutor to one of the state’s most important judicial voices demonstrates how San Antonio legal professionals have helped shape Texas jurisprudence at the highest levels.
Creation of the Texas Criminal Justice Integrity Unit
Perhaps Judge Hervey’s most enduring legacy began in 2008 when she established the Texas Criminal Justice Integrity Unit, a groundbreaking initiative to tackle systemic flaws in criminal prosecutions. Through this innovative program, she transformed how Texas’s legal system handles problematic evidence.
Barbara Hervey designed the unit to focus specifically on issues that frequently lead to wrongful convictions—faulty eyewitness identifications, questionable forensic techniques, and flawed arson science. As a Texas Court of Criminal Appeals judge, she leveraged the unit’s resources to educate prosecutors, defense attorneys, and investigators about evidence-related pitfalls.
Her commitment to fairness is evident in how the unit works to identify and correct problems that undermine the criminal justice system’s integrity, ultimately making Texas prosecutions more accurate and just.
Electoral History and Political Challenges
Judge Hervey’s two-decade tenure on Texas’s highest criminal court reflects her persistent electoral success as a Republican candidate. Since first winning her seat on the Texas Court of Criminal Appeals in 2000, she maintained her position through four statewide elections, demonstrating consistent voter support.
Hervey’s electoral achievements include:
- Securing 78% of the vote in the 2012 general election
- Defeating Democratic challenger Maria T. (Terri) Jackson with approximately 52.7% in 2018
- Winning three consecutive general elections (2000–2018)
- Maintaining Republican support for nearly a quarter-century
- Facing her first significant setback in 2024’s Republican primary
Though she built an impressive electoral record spanning multiple election cycles, Hervey’s judicial career faced an unexpected challenge when she lost to Gina Parker in the 2024 Republican primary.
Judicial Philosophy and Notable Rulings

Barbara Hervey’s judicial philosophy reveals a complex legal mind whose conservative principles typically favor prosecution and law enforcement interests. As a judge on the Texas Court of Criminal Appeals, she often voted to uphold convictions and limit expanded defendant protections, exemplified by her support for a 2014 majority opinion restricting insanity defenses.
In a controversial 2016 case, she joined a majority ruling that permitted the execution of an intellectually disabled man, a decision later overturned by the U.S. Supreme Court.
Yet Hervey has not always ruled predictably. She consistently championed expanded access to post-conviction DNA testing for defendants. Despite her Republican alignment, she occasionally broke ranks with fellow conservative judges, including a dissent from a 2018 decision that upheld restrictions on second-trimester abortions—demonstrating a judicial independence that transcended typical political categorizations.
Teaching Legacy as St. Mary’s Law Adjunct Professor
Beyond her courtroom influence, Hervey’s impact extends deeply into legal education where she has shaped generations of Texas attorneys. Since 1989, she has brought her formidable expertise to St. Mary’s University School of Law as an adjunct professor, delivering practical insights in criminal law and procedure courses.
Her teaching approach consistently yielded results:
- Coached moot court teams to multiple state and national championships
- Supervised countless student internships within Texas’s criminal justice system
- Bridged theoretical education with real-world courtroom experience
- Earned praise from students for her practical teaching methodology
- Established a lasting mentorship legacy spanning over three decades
Hervey’s dedication to educating Texas’s future legal professionals has made her as influential in the classroom as she has been in the courtroom.
Impact on Texas Criminal Justice Reform
For over a decade, Texas criminal justice has undergone substantial transformation under Judge Hervey’s leadership of the Texas Criminal Justice Integrity Unit. As chair of this pioneering initiative, she tackled systemic issues that can lead to wrongful convictions, focusing particularly on reforming eyewitness identification protocols, forensic science standards, and arson investigation techniques.
Her work on the Court of Criminal Appeals has been amplified through the Integrity Unit’s educational outreach, helping prosecutors, defense attorneys, and judges understand critical weaknesses in the system. By addressing these vulnerabilities head-on, she enhanced the fairness and accuracy of Texas criminal prosecutions, earning recognition for her unwavering commitment to justice system integrity and reliability.
