Current 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. Following trial, the court ordered, as we requested, the property manager and managing member removed, and awarded money damages in favor of the investor, including attorneys fees and expenses incurred as the prevailing party.
  • 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. We removed the action to the American Arbitration Association pursuant to the underlying contract, and after trial, at which accounting experts testified, the arbitrator agreed with us that all claims asserted against our client should be dismissed.
  • 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.
  • Prosecuted claims in the U.S. District Court for the District of New Jersey involving fraud, breach of fiduciary duty, and RICO against nationwide co-conspirators due to conversion of $1.2 million.
  • Secured injunctive relief following a bench trial in federal court in the Eastern District of Pennsylvania on behalf of an energy service company to enjoin a competitor shown to be “slamming” the client’s customers through unlawful misrepresentations.
  • Defended monetary claims of over $850,000 brought by a former executive against a New Jersey employer, prevailing in both defeating the monetary claims and proving the employer’s contractual rights to enforce the non-compete and restrictive covenants contained in the executive’s employment agreement.
  • 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.
  • Successfully tried action on behalf of a telecommunications carrier in Pennsylvania concerning real property lease termination issues, and defeated landowner’s claim that it was owed $650,000 under the lease and that the carrier had become a holdover tenant by not properly exercising its right to renew the lease.
  • 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. The judgment arose based upon the judgment-debtor’s disputed payment guarantee for all rent and additional rent owed under a commercial lease with the judgment-creditor.
  • 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 supplier filed suit due to the producer’s failure to deliver natural gas on the daily exchange. 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. The tenant operated a famous restaurant and night club, falsely claiming it was due over $600,000 in rent abatements and damages for breach of the lease due to the landlord’s purported building code violations.
  • Litigated claims in excess of $1.5 million on behalf of a New York real estate developer against a neighboring co-op for nuisance and trespass.
