The Superior Court reviewed the infrequently invoked “no impeachment rule” codified in Pa.R.E. 606. That rule holds, with limited exception, that a juror may not offer testimony regarding what transpired in the deliberation room. One exception — invoked in this case — is when racial animosity leads to the verdict. In Commonwealth v. Rosenthal, the Court acknowledged that some racial jokes were made in the deliberation room, but none were about the defendant or his race or ethnicity. Thus, the judgments of sentence were affirmed.
