Representative Cases

  • Successfully obtained a permanent injunction requiring the City of Phoenix to comply with the Paradise Valley Hillside Development regulations and remove an eight inch above ground water line from Mummy Mountain.
  • Lead appellate attorney in a breach of contract and fraud action involving the sale of commercial property located in the warehouse district of downtown Phoenix.
  • Abromovitz Investment Properties, LLC v. Red Eye Jack Sports Bart, Inc., et. al., Case No. 1 CA-CV 12-0869.
  • Represented an Arizona citizen in simultaneous lawsuits in Colorado State (2008-CV-12) and Federal Court (2010-CV-00813). Our client purchased raw land in a Colorado subdivision that it developed. As part of that purchase our client received water rights to the property. The seller sued our client in Federal Court arguing that our client had interfered with the seller’s ownership of their water rights and sought compensatory damages in excess of $500,000, plus treble damages. The parties, simultaneously, litigated in State Court our client’s ownership of the water and how much our client was entitled to pull from the local river. In the State Court action, the Court confirmed our client’s ownership of the water and the amount owned. The Court also awarded our client attorneys’ fees in the approximate amount of $125,000. In the Federal Court action, the Court entered summary judgment against the seller. The magistrate judge then recommended that our client be awarded his attorneys’ fees, which totaled approximately $225,000. Before the District Court Judge ruled on the fee award, the parties settled the case. The settlement required the seller to: (1) convey their remaining property owned in the subdivision, including the water rights, to our client free and clear of all liens; (2) acknowledge that our client did not commit any wrongdoing; (3) pay $7,500 to draft the settlement documents; and (4) stay away from the property. To ensure that no one ever questioned our client’s integrity, the settlement was filed with the Federal Court so everyone could see the seller’s admission that our client did nothing wrong and that both the Federal and State Court judges ruled that the seller had pursued litigation against our client for an improper purpose.
