A judge ruled on Tuesday that an ex-Temple University employee, Marguerite Jackson, who claims fellow former Temple employee Andrea Constand, 44, told her she meant to fabricate sex assault claims as a way to make money, will be able testify at trial.
The judge has yet to make other rulings in the case, including whether jurors will hear portions of Cosby's deposition from the lawsuit with Constand in which he admits that he has obtained Quaaludes with the intention of using them to seduce women.
During a hearing last week, Cosby's defense team argued Constand's alleged statements to Jackson represent critical evidence for the defense as it demonstrates Constand's intent to set up Cosby and her motive to do so, and undermines Constand's credibility as a witness.
Jackson's testimony is crucial to a defence plan to portray Constand as a greedy liar. Judge O'Neill had deemed Jackson's testimony as hearsay in the first trial, but has now ruled to allow it.
Judge Steven O'Neill said he will reveal his decisions on lingering issues in the case before jury selection resumes on Tuesday in suburban Philadelphia.
The jury questioning revealed some potential witnesses, including Dawn Staley, the SC women's basketball coach who was Constand's boss at Temple; Temple board President Patrick O'Connor, who represented Cosby in Constand's 2005-06 lawsuit against him; and Judge Risa Vetri Ferman, the former district attorney who charged Cosby just before she left office in 2015.
While these rulings have bolstered Cosby's chances of winning this case, jury selection has become a daunting hurdle that the defense team must overcome.
Cosby has denied allegations from more than 50 women that he sexually assaulted them.
The panel so far has four men and three women. In contrast, five jurors were picked on opening day of Cosby's first trial.
Cosby's lawyers had also used two strikes, both to block white women from serving. Almost everyone else in the initial jury pool of 120 suburban Philadelphia residents indicated they knew about the charges against Cosby.
As a effect, scores of potential jurors were sent home because they said they'd already formed an opinion about Cosby's guilt or innocence.
That left just 27 people invited back for individual questioning on Tuesday as prosecutors and Cosby's lawyers work to fill 17 remaining jury spots. A second group of 120 potential jurors was to be brought to the courthouse Tuesday.
The trial is slated to start April 9, assuming the jury is seated.
As jury selection proceeded, The Associated Press and other news organizations challenged an arrangement that forces reporters to watch the proceedings on a closed-circuit feed from another courtroom.
Cosby's lawyers objected to having reporters in the courtroom because they feared it could hurt their ability to find a fair and impartial jury.
Constand met Cosby through her job at Temple University, where Cosby was a trustee, and claims that he drugged and raped her at his Cheltenham home one night after she sought career guidance from the much older entertainer. The camera shows the judge, prosecutors and defense lawyers, but not potential jurors who are being questioned as a group. He says the sexual encounter with Andrea Constand was consensual.
Montgomery County President Judge Thomas DelRicci said he would schedule a hearing on the news media's request. He also ruled that the jury can hear the amount of the settlement that Cosby reached with his accuser.
The AP does not typically identify people who say they are victims of sexual assault unless they grant permission, which Constand has done.
