Assisted an attorney and his zoning board clients in having sanctions imposed by a trial court judge vacated. I helped the attorney in obtaining pre-claim assistance coverage from his insurance carrier and then worked with him to author an appellate brief challenging the sanctions. In an unpublished opinion, the judge writing for the Commonwealth Court agreed with the arguments presented by myself and the client. The Commonwealth Court found that the trial court had no jurisdiction to issue sanctions under Section 2503 of the Judicial Code. The Commonwealth Court also found there was no basis to sanction the attorney or his clients under Rule of Civil Procedure 1701, and that the trial court did not provide appropriate due process before making a finding of contempt. The trial court’s order for sanctions was vacated.

Obtained a judgment for defense on a legal malpractice claim in Dauphin County after a bench trial. Plaintiff asserted the defendant did not properly represent him in an estate matter against his sister which caused him to be evicted from his mother’s house after she passed away. Successfully argued plaintiff could not establish the client ever agreed to represent plaintiff in the estate litigation and performed all of the duties she was retained for.

Obtained summary judgment in a wrongful use of civil proceedings case in the Eastern District Court of Pennsylvania. Successfully argued that client’s defense of probate action was not a “proceeding” as defined by the Dragonetti Act.

Obtained summary judgment in a legal malpractice action in the Eastern District Court of Pennsylvania. Successfully argued that plaintiff could not prove that he would have succeeded in the underlying action without respect for the alleged negligence of clients. Plaintiff’s claim that, had the clients conducted additional discovery, they would have succeeded on the underlying case was belied by plaintiff’s inability to present additional evidence to support the underlying claims during the legal malpractice action. The court reiterated the position that an increased risk of harm does not apply to legal malpractice actions.
