Partner - Public Entity Litigation

As Partner and head of Nachawati Law Group’s Public Entity Litigation division, Brian focuses his practice on representing governments in complex civil enforcement actions in the areas of consumer protection, public nuisance, environmental harms, fraud against taxpayers/false claims, qui tam whistleblower actions, and more.

After joining the New Mexico Office of the Attorney General in 2017, Brian became director of the Consumer & Environmental Protection Division, where he led litigation teams that were successful in recovering over one billion dollars in civil penalties, nuisance abatement, environmental restoration, consumer restitution, debt forgiveness, educational funding, and other remedies on behalf of the people of the State. Brian also helped lead New Mexico’s litigation against the prescription opioid industry, overseeing the largest e-discovery project in State history and serving on the ad hoc committee of governmental claimants in the bankruptcy of Purdue Pharma. In 2019, Brian led a bipartisan coalition of 25 state Attorneys General in demanding that the Federal Trade Commission strengthen protections for children online, and his division’s work litigating against the tech industry has contributed to wholesale changes in the way kids’ mobile apps are marketed and sold today.
