An attorney for a former priest accused of sexually abusing a youth can cross-examine the priest’s accuser on whether he was motivated to make up abuse allegations because he was expelled in the ninth grade from his archdiocesan high school, the judge in the Catholic Archdiocese of Philadelphia sex-abuse case ruled Wednesday.

Philadelphia Common Pleas Court Judge M. Teresa Sarmina also ruled Wednesday that former priest Edward Avery’s counsel can cross-examine Avery’s alleged victim on any potential discrepancies between his grand jury testimony and the allegations he has made in a civil complaint filed by Slade H. McLaughlin and Paul A. Lauricella of McLaughlin & Lauricella and Michael J. Boni of Boni & Zack.
