Jefferson, 50, formerly an appellate lawyer in San Antonio, has been a member of the court since 2001 and was appointed by Gov. Rick Perry in 2004. He is the first African-American to lead the court, the (Austin) Texas tribune noted Tuesday.
"I'm not going to run for other office," Jefferson raid. He added he hopes to "find challenging legal work that will be gratifying, and to continue public service as a private citizen."
During his tenure the court expanded open electronic access to its records and put its hearings online. He has been an advocate of legal aid for those unable to afford legal help, and has encouraged increased pay for judges, the newspaper said.
