Client Wins Damages in Case Involving Pilfered Customer Lists

Jeff successfully represented a broker-dealer before the Financial Industry Regulatory Authority (FINRA) arbitration panel in a case involving two former employees who took, without permission, individual customer lists. They provided the lists to their new employer and successfully converted business, contrary to the interests of the client.

The employees sought to minimize their conduct, asserting that the covenant not to solicit was invalid as a matter of law, that custom in the industry allowed the names to be taken anyway, and that alleged mistreatment by the existing employer excused post-employment obligations. But thanks to Jeff’s persuasive arguments, the panel found that the client was entitled to compensatory and punitive damages, including attorneys’ fees.

Outside the Office

While Jeff enjoys golf as a way to relax outside of the office, he says that in some ways, the game parallels his legal work.

In golf, you develop a strategy for each hole and implement decisions to achieve the best possible result – the fewest number of strokes to the hole. Likewise, he says, clients like to take the fewest steps possible to get to their desired result in litigation.
