Representative Matters:

  • Bill successfully defended a real estate broker in Vasile v. B.S. Real Estate, Inc., where the issue was the alleged failure to disclose a known defect with the structural integrity of a condominium unit. Bill convinced a Philadelphia jury that the broker had no such knowledge and that the broker had no duty to inspect or investigate the property before the sale.
  • In Kramer v, Dunn, the plaintiff alleged that a real estate agent was liable to a buyer for a mistake made by the builder of the property more than thirty years prior. Bill persuaded the Pennsylvania Superior Court that the trial court did not abuse its discretion when it granted his client’s motion for Summary Judgment on the first day of trial.
