A state district court abused its discretion when it attempted to compel a judge to testify in a contempt of court proceeding, the Colorado Supreme Court unanimously held Dec. 19.

The state high court agreed with 21st Judicial District Judge Matthew D. Barrett’s motion to quash a subpoena compelling him to sit for a deposition in his judicial capacity. The panel said it was not convinced that Barrett possessed factual knowledge pertinent to the contempt charge against Tina Peters.
