Reported Cases:
Significant Representative Matters: Successfully defended a home inspector before the Delaware Division of Professional Regulation. The Claimants sought disciplinary action against our client in connection with his inspection of their home. We were able to persuade the Division that the complained of defects at the property were not subject to inspection because they were not visible at the time of inspection. The Division weighed all concerns involved in the matter and on November 1, 2023, it concluded that the facts did not reflect a violation of the laws, rules, and regulations that governed the activities of the licensed professional.; A unanimous jury found in favor of our clients, a lawyer and his law firm in a legal malpractice case arising out of the lawyer's drafting of a postnuptial agreement. The postnuptial agreement was invalidated by a family court judge, causing the husband to lose approximately $1.2 million as part of a subsequent property separation agreement. The jury considered testimony from the plaintiff's ex-wife which reflected that she had signed the agreement under duress, and concluded that the plaintiff could not demonstrate that the postnuptial agreement was invalidated as a result of anything the lawyer did.; Plaintiff claimed that estate attorneys misinterpreted stock restriction agreement causing Plaintiff's husband's estate to lose in excess of $1 million. Court held that agreement was properly interpreted by attorneys; Attorney prosecuted civil rights claim on behalf of mother of son who was shot and killed by a Philadelphia police officer while unarmed and posing no threat to the officer. Mother of decedent served as administrator of estate and retained proceeds of settlement. Decedent allegedly had two children who should have received the proceeds. Attorney sued by children's mother on their behalf. Plaintiff's minor children made $1 million settlement demand just prior to the court's dismissal of the claims.; Plaintiff claimed that his attorney failed to properly prosecute his workers' compensation claim causing his benefits to be discontinued. Plaintiff's claims dismissed by way of summary judgment motion.; Buyers of real property sued real estate agent for seller, claiming misrepresentations regarding use of the property. Claims dismissed by way of summary judgment motion.; Success in getting a number of legal malpractice cases dismissed promptly by way of preliminary objections. In such cases, the Plaintiff failed to allege facts that, even if true, could yield liability as to our client.; Success in getting a number of legal malpractice cases dismissed upon the filing of motions for non pros as a result of opposing counsel's failure to comply with the Pennsylvania Rules of Civil Procedure.; Summary judgment and motions to dismiss granted on behalf of a number of clients. In one recent case, the plaintiff claimed that our attorney client was liable to him for wrongful use of civil proceedings and was seeking in excess of $3 million in damages. Upon the filing of a Motion for Summary Judgment, the court dismissed our client, finding no liability whatsoever.; Success in defending clients at arbitration hearings and bench trials, including cases involving alleged home inspector liability and insurance subrogation claims.; Published Works: 'LPL Claims Without Privity: Support for a Bright Line Rule', Professional Liability Defense Quarterly, Fall 2018; 'Proving The 'Case-Within-A-Case' Standard,' For The Defense, April 2018; 'Demonstrative Evidence at Trial', Pennsylvania Civil Trial Practice, 2017, 2018, Reviewing Author; 'Common Evidentiary Issues at Trial', Pennsylvania Civil Trial Practice, 2017, 2018; 'Responsive Pleadings', Pennsylvania Civil Pre-Trial Practice, 2017, 2018, Reviewing Author; Pennsylvania Legal Malpractice Handbook, 2017 Edition, 2019 Edition, Published by Marshall Dennehey Warner Coleman & Goggin, Co-author; 'Pennsylvania Supreme Court Rejects Constitutional Challenge to the Dragonetti Act,' Defense Digest, Vol. 23, No. 2, June 2017; 'An Argument Against Imposing Liability Against Attorneys for Aiding and Abetting Their Client's Breach of Fiduciary Duty Under Pennsylvania Law,' Defense Digest, Vol. 17, No. 4, December 2011; 'Former Phillies Tyler Green Thrown a Curve on Appeal for Legal Fees, ' Defense Digest, September 2007; 'Medical Malpractice Plaintiff's Motion for Relief from Judgment of Non Pros Lacks Merit, ' Defense Digest, March 2007; Regular contributor to MDWC&G Case Law Alerts.
