Bill Cosby’s sentencing hearing Monday will begin with testimony about his sex offender evaluation and, presumably, a fierce debate over whether the 81-year-old actor should be branded a sexually violent predator.

The stakes are high given the lifetime counseling, community alerts and public shaming the designation would trigger. And it could become evidence in the defamation lawsuits filed against Cosby by accusers who say he branded them liars when he denied molesting them.

Defense lawyers say the state’s latest sex-reporting law, despite several revisions, remains unconstitutional.

“It’s the modern-day version of a scarlet letter,” said lawyer Demetra Mehta, a former Philadelphia public defender, “which I think is sort of an interesting philosophical issue at this time with the #MeToo movement, but also criminal justice reform.”

Pennsylvania’s sex-offender board has examined Cosby and recommended he be deemed a predator, concluding that he has a mental defect or personality disorder that makes him prone to criminal behavior. Montgomery County Judge Steven T. O’Neill will have the final say Monday.

O’Neill has presided over the case for nearly three years, from shortly after Cosby’s December 2015 arrest to a 2017 trial that ended in a jury deadlock to the jury finding this past April that Cosby drugged and molested a woman at his suburban Philadelphia estate in 2004.

It’s unclear if the judge, in weighing the predator label, will consider the dozens of other Cosby accusers who have gone public or his deposition in the trial victim’s 2006 lawsuit, when Cosby acknowledged getting quaaludes to give women before sex; described sex acts as the “penile entrance” to an “orifice” and “digital penetration”; and said he often gave young women alcohol but didn’t drink or take drugs himself because he liked to stay in control.

Defense lawyers fighting the predator label note that sexual offender registration laws are in flux in Pennsylvania and elsewhere.

Numerous courts, including the Pennsylvania Supreme Court, have found the laws so vague as to be unconstitutional. Courts have also debated whether the programs unfairly amount to extra punishment, especially for people convicted of misdemeanors. Cosby has added one of the state’s top appellate lawyers, Peter Goldberger, to his defense team.

“This is going to probably be a very important case for sex-offender law when it’s up on appeal,” Mehta said.
