Thursday's ruling overturning Harvey Weinstein's New York rape conviction gives the one-time film mogul a chance at a new trial and calls into question what evidence prosecutors can use in future sex crime cases. But a 4-3 majority of the New York Court of Appeals, the state's highest court, found that the trial judge should not have permitted three other women to testify that Weinstein had assaulted them as well because their allegations were not part of the criminal charges against him. Such testimony about "prior bad acts" is usually barred by New York's so-called Molineux rule, named for a landmark 1901 court case.
