AUSTIN, Texas — One of the state lawmakers instrumental in delaying Robert Roberson’s execution, Jeff Leach, allegedly texted a Texas Court of Criminal Appeals judge last week asking for a new trial.

The judge declined to consider the message and the court has been found to lack any jurisdiction in the case. Still, Texas Attorney General Ken Paxton sent an email to the Texas Supreme Court Friday, notifying them of the breach of professional conduct.

Representative Jeff Leach sits on the Texas House Committee of Criminal Jurisprudence, which issued the subpoena for Roberson that ended up delaying his execution. In text messages between him and a Texas Court of Criminal Appeals judge, he wrote he wasn’t aware the matter was already pending and apologized.

Defense attorney and former prosecutor Ty Cardenas-Wittenstein says attempts to influence a judge outside the courtroom can have major ramifications.

“That’s literally what our system is based on, is justice and fairness,” Cardenas-Wittenstein said. “You’re going to ruin the case. In a criminal case, anybody getting involved like that could easily cause a mistrial, which means everything is stopped.”

She says this is called ex parte communication when one party tries to communicate with the judge about the case without the other parties present.

“One of those lawyers can’t go and, you know, tell the judge a secret or send a secret letter, or even some sort of a social media post or something like that.” Cardenas-Wittenstein said.

This violation typically involves lawyers, but it doesn’t always have to.

“It can be an investigator. It can be it can be a paralegal,” Cardenas-Wittenstein said. “Anybody that’s on either of the teams, whether they’re directly involved or loosely involved.”

That’s why the Office of the Attorney General says State Representative Jeff Leach violated Texas disciplinary rules of professional conduct when he texted a judge who sits on the Texas Court of Criminal Appeals last week, in an attempt to get her to vote favorably in delaying Robert Roberson’s execution and getting him a new trial.

Roberson is on death row for the 2002 murder of his two-year-old daughter Nikki Curtis, but many including Leach believe he wasn’t given a fair trial.

In a letter reporting the violation that was sent to the Texas Supreme Court and attorneys involved in the case, his text messages were revealed. He allegedly wrote in part…

“I’ve wracked my brain about whether I should send you this message about where I can even send you this message legally and ethically… There are too many questions and too many holes and too much uncertainty and Robert Roberson deserves a new trial.”

Leach explained to the judge he wasn’t a party to the trial and the case wasn’t actively pending, but the judge replied the matter was indeed pending and thus ex parte communication she couldn’t consider or discuss.

Leach apologized for the error, but the judge still reported the communication.

“For most lawyers, it’s something that you know is ingrained to us,” Cardenas-Wittenstein said. “But you know, for somebody that didn’t go to law school, I don’t know if that would be something that was ingrained in them.”

On the social media platform X Monday evening, Leach apologized publicly. He says in part:

“Unlike some other leaders in our state, I’m not afraid to admit when I mess up and that’s exactly what I did… I am fiercely committed to the rule of law and to strengthening our system of justice. This is why I’m so passionate about the case of #RobertRoberson — because I believe so strongly the system has failed him.”

Cardenas-Wittenstein says ex-parte communication can sometimes lead to a case being thrown out or a lawyer even losing their license to practice. In this case, though, it doesn’t involve an attorney and the United States Supreme Court has already ruled the Court of Criminal Appeals lacks jurisdiction, sending the case to the Texas Supreme Court where it’s still pending.

CBS Austin reached out to one of Roberson’s attorneys listed in the letter, who declined to comment. We’re also waiting to hear back from the Anderson County District Attorney who was also notified of the violation.
