But Judge O’Neill said that the negotiations that led to the settlement would not be disclosed. Prosecutors had wanted to include what they said were Mr. Cosby’s demands that he be released from criminal liability and that Ms. Constand be barred from cooperating with the police — a stance, prosecutors said, that was inconsistent with a person saying he was innocent.

The rulings came on the second day of jury selection for the trial, scheduled to start next week. Seven jurors have been selected so far. In a sign of the challenge in finding an impartial jury, 82 of 119 potential jurors questioned by the judge Tuesday said they already had an opinion about Mr. Cosby’s guilt or innocence.

As to his decision regarding Ms. Jackson, Judge O’Neill said it was “subject to further rulings by this court in the context of trial, specifically, following the testimony of Andrea Constand” — suggesting the decision could be reversed depending on Ms. Constand’s testimony.

Ms. Jackson has worked for more than 30 years at Temple, and said in an affidavit filed with the court that she traveled with its women’s basketball team as an adviser in the early 2000s, sometimes sharing a room with Ms. Constand, who was the team’s operations manager. Ms. Jackson said on a trip to Rhode Island during that time they watched a TV news report together about a prominent person who had drugged and sexually assaulted women.

Ms. Constand responded to the TV report, Ms. Jackson said, by saying at first that something similar had happened to her. Then she said she had not actually been assaulted but that she could make a lot of money if she told the authorities that she had been, according to the affidavit.

“I could say it happened, file charges and get money to go to school and open a business,” Ms. Constand said, according to Ms. Jackson’s account.
