When a lawyer is served with a malpractice suit, throwing the complaint on the floor, ejecting the process server for trespassing and yelling “call 911″ are possible responses.

But they’re wrong, a Mercer County, N.J., judge says in a $403 sanction order against Robert Conroy, one of the state’s leading health care lawyers.

Conroy was in his Bridgewater office on March 20, when Guaranteed Subpoena Service Inc. sent a representative to serve a malpractice suit by a doctor Conroy had represented in a complicated transaction.

But Guaranteed reported back to the plaintiff’s lawyer: “Not served! Entity was evading service. Threw service at server, stating he was trespassing and would be arrested if he didn’t leave.”
