NEW YORK (JTA) — Twelve former students joined a $380 million lawsuit against Yeshiva University for covering up sexual abuse at its high school.

The new plaintiffs’ names came out in court papers used in a hearing Tuesday in U.S. District Court in White Plains, N.Y., according to the New York Daily News, and bring to 31 the number of plaintiffs in the case.

Rabbi George Finkelstein and Macy Gordon, former staff members at Y.U.’s High School for Boys in Manhattan, as well as a youth volunteer, Richard Andron, have been accused of sexual abuse. Some of the cases allegedly took place as far back as the 1970s.

Finkelstein left the high school in 1995 and took a post at a Jewish school in Florida before moving to Israel. Gordon also lives in Israel and until recently was a teacher at the Orthodox Union’s Israel Center. Both men deny the charges. Andron has not issued a statement on the accusations.

The suit also names top members of Y.U.’s former administration, including Norman Lamm, its former president and chancellor.

Although the statute of limitations has passed on the cases, the alleged cover-up could negate the restrictions, according to Kevin Mulhearn, the plaintiffs’ attorney.
