A Queens judge with a history of bizarre behavior faces removal from the bench for a series of misdeeds capped by his repeated refusal to cooperate with an ethics probe — which state officials say he called a ­“f–king clown show.”

Queens Civil Court Judge Terrence O’Connor — previously censured in 2013 — was under investigation for abusing his power when, on March 7, 2017, he refused to testify under oath at a disciplinary hearing, the state Commission on Judicial Conduct said Wednesday.

Following the hearing, two staffers heard O’Connor fume “This place is a f–king clown show” as he stormed out, according to the commission, which in an 11-0 vote recommended that he be ousted.

The panel said that it opted not to hold the remark against him, but that O’Connor’s repeated misconduct merited bringing the gavel down on his judicial career.

O’Connor, a Democrat whose annual salary is $193,500, has until May 2 to challenge the recommendation or be automatically booted by the Court of Appeals.

The ruling cited two incidents in which O’Connor struck witnesses’ testimony and tossed their cases because the lawyers questioning them merely said, “OK” upon hearing the replies.

The commission also faulted O’Connor for publicly lambasting three lawyers who appeared before him, including a rookie attorney who made the mistake of texting his boss when O’Connor unexpectedly ordered him to begin trying a case for which he wasn’t prepared.

“Is there some course in law school now, how to be discourteous and how to be rude? Because if there is, you must have gotten an A in it,” O’Connor barked.

The commission also said O’Connor’s misconduct was “significantly compounded” by his refusal to cooperate with its investigation through repeated “evasion, avoidance and delay.”

O’Connor is the son of the late Frank O’Connor, who served as Queens DA, City Council president and an appeals-court judge.

Terrence O’Connor was elected to a 10-year Civil Court judgeship in 2008.

The following year, while assigned to Family Court, he tangled with lawyer and state Sen. Tony Avella, who was representing a woman in a custody case.

When O’Connor refused to postpone a hearing while the woman recuperated from surgery, Avella complained in a letter to O’Connor’s boss and faxed O’Connor a copy — which the judge shredded and mailed to Avella.

Avella applauded Wednesday’s action, saying, “Judges are not above the law. Justice is served.”

Lawyer Jack Glasser said, “He shouldn’t have been removed from the bench, he should’ve been put to death . . . This man has hurt so many people.”

O’Connor declined to comment directly, but had a court officer tell The Post he planned to appeal the commission’s ruling.
