NEW YORK (AP) — The jury in Harvey Weinstein’s rape trial indicated Friday that it is deadlocked on the most serious charges against the once powerful Hollywood mogul, but the judge told the panel it must keep working.

In a note to the judge late in the fourth day of deliberations, jurors asked if it was permissible for them to be hung on one or both counts of predatory sexual assault while reaching a unanimous verdict on the other charges.

Weinstein’s lawyers said they would accept a partial verdict, but prosecutors said no and Judge James Burke refused to allow it. He sent jurors back to deliberate for a few more minutes before letting them go home for the weekend. They’ll resume Monday morning.

“It is not uncommon for a jury to have difficulty initially in reaching a unanimous verdict, and it is not uncommon for a jury to believe that they will never be able to reach a unanimous verdict,” Burke said, reading instructions to the jurors. “But after further deliberations, most jurors are able to reach a unanimous verdict.”

The jury posed its deadlock question in hypothetical fashion, writing: “We the jury request to understand if we can be hung on (Count) 1 and/or (Count) 3 and unanimous on the other charges? Thank you.”

One reason for that phrasing could be that the verdict sheet — which lays out the charges — doesn’t include instructions for what to do if they can’t agree on a particular count, only how they’re supposed to proceed once they’ve reached a verdict of guilty or not guilty.

The way the sheet is designed, jurors are supposed to first reach a unanimous verdict on the predatory sexual assault counts, which carry a maximum penalty of life in prison, before they can even consider the other three counts.

Law professor Cheryl Bader said the note suggests the jury is split on a key aspect of both predatory sexual assault counts — “Sopranos” actress Annabella Sciorra’s allegations that Weinstein attacked her in the mid-1990s — and that it is in unanimous agreement on the allegations by two other women — an aspiring actress who says he raped her in March 2013 and a former film and TV production assistant, Mimi Haleyi, who says he forcibly performed oral sex on her in March 2006.

Weinstein has maintained any sexual encounters were consensual.

“It’s not unusual for the judge to have them keep deliberating and not just give them a pass at the first sign of trouble,” said Bader, a former federal prosecutor who teaches at Fordham University School of Law.

The defense said speculating on the verdict at this point “would be premature and a mistake.”
