Representative Matters

  • Representation of a federal student loan servicer in litigation in which a state attorney general challenged all aspects of the servicer’s performance, including its administration of several federal loan forgiveness programs. After a lengthy litigation that received national and Congressional attention, the matter was resolved on a no admission, no penalty basis.
  • Representation of a publicly-traded energy company in a DOJ investigation relating to the company’s participation in the political process. After a lengthy investigation, the government declined to pursue charges against the company or its executives.
  • Representation of a federal student loan servicer challenging the legality of Connecticut and California state licensing requirements. In decisions of first impression in the Second and Ninth Circuits, the federal courts granted summary judgment in the servicer’s favor, finding the state licensing requirements were preempted as applied to federal student loan servicing.
