Mr. Adamski started out his practice as a litigator. His primary focus now is providing legal assistance and counseling to individuals, businesses and public entities.

He regularly represented the franchise in its ongoing relations with both the City of Oakland and the County of Alameda.

Mr. Adamski’s more interesting legal experiences include:

  • Developed and implemented a litigation strategy which allowed our client, a minority general partner, to emerge as the sole owner of the Golden State Warriors
  • In a landmark case involving domain names, developed a unique use of a federal preliminary injunction motion which resulted in the return to our client of the domain name
  • Defended the Golden State Warriors against a $30 million claim for breach of agreement involving the potential sale of Personal Seat Licenses for Warriors games played at the Oakland Alameda County Coliseum Arena
  • Asserted claims on behalf of the Warriors against the owners of the Arena resulting in amounts paid or credited to the team in excess of $15 million as well as the right to certain other revenues generated at the Arena

  • Defended Atascadero Mutual Water Company (AMWC), one of the state’s largest and oldest mutual water companies, against claims it was improperly extracting groundwater from the Paso Robles Groundwater Basin. The action resulted in the courts and public entities recognition that: (a) AMWC draws water from the Atascadero Sub-basin a distinct and legally separate hydrologic unit from much larger Paso Robles Groundwater Basin; (b) AMWC had a common law right to withdraw water from the Sub-basin and (c) the Sub-basin was not in overdraft
  • Represented landowners owning thousands of acres of farmland in the longstanding adjudication of the Santa Maria Groundwater Basin
