International law firm Bryan Cave Leighton Paisner announced the addition of Partner Daniel P. Mach to the Litigation & Investigations Department. Dan will be resident in BCLP’s New York office. Dan joins from Quinn Emanuel.

Dan brings with him significant experience in both trial and appellate litigation, successfully representing clients in high-stakes matters involving billion or multi-billion dollar damages claims. Dan often advises clients in the financial, energy, pharmaceutical, and other industry sectors across consumer and employment class actions as well as litigation involving complex commercial/contract, antitrust, intellectual property, corporate governance, and environmental/energy issues. He has appeared and argued in state and federal courts, numerous state and federal administrative tribunals and commissions, and in private arbitrations.

Prior to his time at Quinn Emanuel, Mach notably clerked for the Hon. F. Dennis Saylor IV of the United States District Court for the District of Massachusetts and for the Hon. Susan P. Graber of the United States Court of Appeals for the Ninth Circuit.

“Dan’s skill set will be a wonderful addition to our Litigation Department, and specifically to our Appellate Practice, as we continue to build depth and talent across our firm,” noted Partner Jean-Claude André, co-chair of the Appellate & Supreme Court Group. “He has a strong track record in high-stakes disputes and we are excited to welcome him to the firm.”

Dan regularly speaks on cutting-edge legal questions facing clients and the litigation risks they present. Recent examples include CLE presentations on environmental, social and governance (ESG)-based financial instruments and investment funds, and regulatory measures related to them in the U.S. and Europe; recent developments in “climate tort” litigation and the remove-ability of state-law nuisance claims against industries based on historic carbon emissions; and the Biden administration’s initiative to lease federal waters for large-scale offshore wind development, with related environmental assessment and permitting risks. He has authored publications and articles on topics including the rise of financial-sector “greenwashing” litigation claims, current trends in environmental assessment litigation under state and federal law, and energy infrastructure siting.

“Dan’s dynamic experience as a litigator will be a huge asset to our clients and our firm overall,” said Global Department Leader of Litigation & Investigations Lee Marshall. “Our Litigation & Investigations Department is an important component of BCLP’s growth strategy, and we are excited to welcome Dan to the firm.”
