Relevant Experience

  • Successfully filed claims for breach of fiduciary duty and breach of contract in the Kansas District Court and Delaware Chancery Court on behalf of a real estate investor concerning a multi-family apartment complex in Kansas.

  • Defended against accounting, conversion, breach of fiduciary duty and breach of contract claims asserted against our client, a national money service agent, in New York State Supreme Court.

  • Defended foreign corporation in the U.S. District Court for the Southern District of New York concerning a complex business agreement in which the purported finder asserted that his company was due a 10% finder’s fee for bringing a $20 million business opportunity to the foreign corporation. The case was dismissed prior to trial on summary judgment.
  • Successfully tried a diversity action in the U.S. District Court for the Eastern District of New York on behalf of a well-known telecommunications carrier to secure injunctive and declaratory relief concerning the carrier’s access rights to its telecommunications equipment and rights to improve its underground lines with fiber optics. Defeated the landowner’s claims that it was owed rent escalations under the long-term lease in exchange for the carrier’s right to enhance its equipment.
  • Defended a Will contest in the California Superior Court involving a relative’s claim that the decedent’s Last Will should be rejected on grounds of fraud, undue influence, and forgery, and that the relative was owed 50% of the decedent’s $30 million gross estate. Following trial, argued the dispute before the California Court of Appeals, which affirmed the trial court’s decision in all respects.
  • Litigated claims before the American Arbitration Association in Manhattan concerning asserted rights to recover over $450,000 in connection with the client’s $2.5 million investment in an upscale restaurant that had closed due to claims of the operator’s mismanagement and breaches of fiduciary duty.

  • Obtained an injunction in New Jersey Chancery Division to enjoin a client’s principal competitor from defaming and disparaging the client, which defamation could have caused immeasurable damages if it were not enjoined.

  • Uncovered assets to hasten a favorable settlement on behalf of a judgment-creditor owed $500,000 from a major national restaurateur who had refused to satisfy any part of the judgment issued after trial in the New York Supreme Court, Westchester County.

  • Represented a large international energy producer based in Texas in defense of a contract claim filed in the New Jersey Superior Court in which a downstream natural gas supplier asserted that it was owed over $775,000 in compensatory damages and legal fees.

The defense invoked the force majeure clause contained in the NAESB industry contract based upon an unforeseen gas leak and disruption in the Tennessee pipeline.
  • Evicted a commercial tenant on behalf of a well known hotel in midtown Manhattan after a twelve-day bench trial in New York Supreme Court, New York County.
