Client Work

  • When the U.S. Court of Appeals for the Ninth Circuit took on a case with potentially devastating repercussions for a client, Robert was part of the Schiff Hardin team that crafted an amicus brief for the court. The brief focused the court’s attention on the injustice underlying the appellees’ positions and the dire consequences of acquiescing to the appellees’ requests.
  • Robert represents clients in environmental citizen suits – actions brought by private citizens and organizations alleging violations of law – including ongoing litigation against a multinational organization to ensure investigation and, potentially, remediation of a future public park in Brooklyn, New York.
  • Robert is always ready to negotiate on behalf of his clients. Robert has extensive experience assisting clients in negotiating agreements to access private property to execute remedial efforts. These negotiations have included everything from simple access agreements to land purchases.
  • In his first year of practice, Robert secured a favorable jury verdict for his pro bono client in a landlord-tenant dispute. This bitter dispute afforded Robert the opportunity to single-chair a jury trial and develop invaluable experience in settlement negotiations, motion practice, oral arguments, and client counseling.
