A former Maryland judge Thursday was sentenced to a year’s probation for ordering a sheriff’s deputy to administer an electrical shock to a defendant in his courtroom.

Robert C. Nalley, who had been on the Circuit Court bench in Charles County, had pleaded guilty to a misdemeanor charge of violating the civil rights of the defendant, Delvon L. King, as King was about to face trial on a gun charge in 2014.

“To say that I’m chagrined to be standing here is an understatement,” Nalley said in brief remarks in U.S. District Court in Greenbelt. Nalley said he felt “deep regret” over his “error in judgment,” which he said reflected not just on himself but on his family and the county justice system. Nalley did not apologize to King, who was in the spectators’ gallery a few feet away, or make any reference to him.

King, 27, said in court that Nalley “tortured” him and deprived him of a fair trial. Nalley had a deputy shock King, who was representing himself, as he made what he believed was a legal argument during jury selection on July 23, 2014. King dropped to the ground when a 50,000-volt shock was administered through a Stun-Cuff attached to his ankle.

After paramedics determined King was not seriously injured, Nalley continued jury selection. On Thursday, King told U.S. Magistrate Judge William G. Connelly he was disoriented and fearful after being shocked and was not able to defend himself to the best of his abilities.

During the sentencing hearing, federal prosecutors played a videotape of the incident and, separately, an audiotape. The videotape shows King calmly spread about a dozen stacks of paper on the defense table. Nalley takes the bench. Later, King drops to the ground, falling on his right side.

Nalley, 72, retired from the bench in September 2013.
