  • Confidential federal False Claims Act investigation. Harry is defending an individual in a confidential federal false claims investigation.
  • Rosenblum et al. v. Oracle, Inc. et al. Represented the State of Oregon and Cover Oregon in litigation against Oracle, the second-largest software company in the world.

Firearms/Second Amendment Litigation

Harry served as first-chair trial lawyer and led a team defending the Governor, Attorney General, and Superintendent of the Oregon State Police in four consolidated federal cases challenging the constitutionality of Oregon’s restrictions on large-capacity magazines and permits to purchase firearms.
