A New Jersey judge blew up at the mother of an alleged sexual assault victim during a court hearing, telling her to “keep your mouth shut” and “sit down” after she complained about delays, according to a new report.

The mom was in court on June 28 for a hearing in John Angeline’s case when she was called out by Middlesex County Superior Judge Joseph Rea, NJ.com reported.

“You just found out that you were looking at the victim, and you still kept that tone of voice,” the mom told NJ.com about Rea’s remarks.

Angeline, 44, an ex-English teacher at South Plainfield High School, is charged with sexually assaulting the woman’s son when he was 15 on numerous occasions between 2010 and 2013. None of the alleged assaults occurred at the school.

The judge confronted the mother, whose name is being withheld to protect her son’s identity, for scoffing at the back-and-forth between lawyers during the hearing.

“What’s the problem back there?” Rea asked. “Excuse me, if you have enough nerve to make some noise, stand up and be heard. What’s the problem?”

The mom complained that she and her son, who was by her side that day, have endured four and a half years of “constant delays and pushbacks” as the case wound through court. She then identified herself as the victim’s mother when the judge asked her who she and her son were.

“The case is going to go to trial, all right? You’re not the only case on the list,” Rea said. “There’s a bunch of cases on the list. Both these lawyers have a pretty busy calendar. What we’re trying to do now is get a firm date. Is that a problem?”

“All the back-and-forth is a problem. It is,” she answered. “October 9, October this. We were supposed to be here in June, and now we’re going to October. Initially, it was going in 2020 and that’s where we feel like we’re going to end up. All I’m asking for is fairness for this case. Please. Please.”

Rea, who’s been on the bench since 2003, told the woman to take her issues up with the prosecutor’s office.

“Because you’re being inappropriate,” he said. “Keep your mouth shut. Sit down.”

Then he began ranting that he felt “frustrated” over receiving “all kinds of phone calls and letters that are completely unwarranted.”

“Which, quite frankly, I think the State Police are going to get involved in,” the jurist said, without elaborating on what the calls and letters were about.

He then seethed at the mom, “I don’t make plea offers, ma’am! The prosecutor’s office does,” before setting an Oct. 22 trial date.

Prosecutors had offered Angeline a no-jail plea deal that also would have let him avoid registering as a sex offender — before yanking the agreement.

The woman admitted that she acted out in court, but said the judge’s comments were hurtful.

“I know I was wrong. I understand that,” she said.

She said she has little faith that the trial will be fair, in light of all the delays and the judge’s outburst.

“This is why victims don’t come forward,” she said.

Two other jurists in New Jersey have come under fire for offhand remarks in rape and sexual assault cases.

Burlington County Superior Court Judge John Russo is facing disciplinary action for telling a rape victim to “close her legs” to avoid forceful sex, while Judge James Troiano of Monmouth County Superior Court said a teen accused of raping a girl should get leniency because he comes “from a good family.”
