  • Represented several cardiologists who were accused by their former employer of violating covenants not to compete. Two of the matters settled before any significant motions practice, and the employer subsequently dropped the matter entirely as to a third cardiologist.
  • Represented a real estate developer who originally sued his former partner in a contract dispute. The former partner filed a 19-count complaint against our client and the lawyers that represented him in the original litigation. The firm drafted a comprehensive motion to dismiss all counts, and shared it with opposing counsel before filing it with the court. Opposing counsel agreed to dismiss the entire lawsuit with prejudice.
  • Entered our appearance on behalf of party against whom a multimillion dollar judgment was entered by a Maryland trial court. The prevailing party sought in excess of $4 million in attorney’s fees pursuant to a contractual fee-shifting provision. After a four-day bench trial, the Circuit Court awarded the prevailing party $0 in attorney’s fees in response to our argument that the prevailing party had been overcompensated by the original judgment. Although this ruling was reversed on appeal, the appellate court directed entry of an attorney’s fees award of only $1.4 million, based on the trial court’s alternative finding that the prevailing party was not entitled to several million dollars in legal fees.
  • Assisted with a merits brief concerning Article III standing heard by the U.S. Supreme Court in October 2011. On the last day of the term, the Supreme Court dismissed the writ of certiorari as having been improvidently granted, thereby affirming the lower court’s ruling in our client’s favor.
  • Represented senior officers and their corporation in connection with investigations by the Maryland State Prosecutor and the Federal Election Commission (FEC) concerning alleged campaign finance rules violations. Both matters settled, and the firm continues to provide advice to the corporation about the law of campaign finance.
