A federal judge who was arrested last summer in Atlanta on accusations of domestic abuse resigned on Friday.

The judge, Mark E. Fuller of the Middle District of Alabama, was arrested and charged with battery in August when Kelli Fuller, then his wife, called the police from a Ritz-Carlton in Atlanta, saying he had assaulted her during an argument about her suspicions that he was having an extramarital relationship with a law clerk.

Judge Fuller entered a pretrial diversion program, which he completed. That led to the dismissal of the criminal charges. Still, the pressure on him to resign continued. He also remains under investigation by a five-judge panel.

On Friday, Judge Fuller sent a two-sentence letter to President Obama, saying, “It has been an honor and privilege to serve.” His resignation will be effective on Aug. 1.
