Quinn Emanuel Urquhart & Sullivan associates David LeRay and Nicolas Siebert have become somewhat accustomed to basking in the glow of the firm's victories against big banks in high-stakes antitrust cases. LeRay and Siebert were part of the firm's Litigator of the Week award-winning team last month that struck a nearly half-billion deal with multiple banks accused of conspiring to prop up fees in the stock lending market. LeRay, who has been with the firm since 2013, also had roles on the firm's teams that brought antitrust cases related to credit default swaps and interest rate swaps.
