Denis J. Lawler

Denis Lawler has spent his entire career trying cases. Most recently, those matters have involved:

  • The defense in arbitration of a supplier who had terminated a long-term supply contract on the grounds of impossibility, resulting in a defense verdict and the award of $1,000,000 in attorneys’ fees under a fee-shifting provision in the contract involved;
  • The defense of a seller of a business against claims of breach of warranties and representations in the sale; the liability phase had been lost by predecessor counsel; in the trial of the damages phase, plaintiff’s $30,000,000 claim based on an economist’s report was thrown out, resulting in a minimal award, which in turn led to a filing by the plaintiffs of new actions in federal court under RICO; and most recently,
  • The defense of corporate fiduciaries in trust matters before Pennsylvania Orphans’ Courts.

Mr. Lawler has received the highest possible rating from Martindale-Hubbell.

Representative Experience

  • Legal professional liability matters involving disputes between law partners, recovery of funds from embezzling attorneys, and defense of malpractice claims.

  • First jury trial: the defense of first-degree murder charge, one year out of law school, with his father at counsel table, resulting in a voluntary manslaughter verdict.
