Brittany Sukiennik

Brittany L. Sukiennik focuses her practice on complex litigation, including mass torts and other commercial disputes. She routinely navigates some of the most expansive and high stakes cases, with particularly significant trial experience in courts across the nation.

• Represented Robinhood in dozens of lawsuits, centralized in Florida federal court, including numerous putative class actions—securing a string of victories over more than three years to dismiss or otherwise resolve all claims against the company. The actions involved antitrust, contract, securities and various other state and federal claims arising out of Robinhood’s decision to temporarily place certain limits on trading in certain securities in the face of unprecedented market volatility. Ms. Sukiennik secured decisions dismissing all antitrust and state law claims filed against Robinhood, both of which were affirmed on appeal, and obtained a major ruling defeating class certification of the securities claims.
• Representing PG&E in connection with mass tort litigation related to the California wildfires between 2019 and 2021. She previously represented the company in numerous lawsuits arising out of the unprecedented 2017 and 2018 California wildfires—one of the largest and most complex sets of mass tort litigation in recent years.
• Representing Xcel Energy, a major U.S. electricity and natural gas company with operations in eight states, in hundreds of lawsuits filed against Xcel arising from the December 2021 Marshall Wildfire.
