During a defamation trial, Judge Holt announces he attended the press conference at issue and offers to describe to the jury how the reporter framed her questions. The parties object. The court must reject the offer because the president judge cannot serve as a fact witness in the proceeding over which he presides.
In a construction-defect suit, the president judge conducted a pretrial visit to the collapsed balcony. When experts later disagree on rebar placement, the judge offers to testify about conditions observed on site. Pinnacle Homes objects. The court must decline the testimony to avoid placing the presiding officer in the role of witness.
During an impeachment trial, the president judge learns he possesses personal knowledge of contested facts. He considers stepping aside to testify. Counsel for the impeached officer objects. The court must keep the president judge from testifying to preserve the structural separation between arbiter and witness.
A journalist subpoenaed to testify in a criminal case moves to quash on First Amendment grounds. The president judge reviews the subpoena and determines that the reporter's observations occurred outside the courtroom. The court denies the motion because the president judge's own potential testimony is separately barred by the evidence rules.
In a murder prosecution, the defendant seeks to shift the burden of proving extreme emotional disturbance to the state. The president judge rules on the allocation of proof. The defendant objects that the ruling invades the jury's fact-finding role. The court upholds the allocation because the president judge's decision concerns only the legal framework, not contested facts.
The prosecution offers a co-conspirator's out-of-court statement against the defendant. The president judge must decide preliminary questions of admissibility. Defense counsel argues the judge should recuse because of prior exposure to related facts. The court denies recusal because the president judge's role in gatekeeping evidence does not convert the judge into a witness.
