Representative Cases

Steve has a particular depth of experience in several types of business and commercial disputes, including: investment disputes and business divorces; real estate litigation; healthcare litigation; and contract disputes in the power, gas and coal industries. Examples of client successes in these areas include:

Investment Disputes And Business Divorces

  • A $20 million arbitration award in favor of investors for mismanagement and securities fraud in two closely-held investment vehicles;
  • Favorable settlements for five former clients of broker Frank Gruttadauria, who misappropriated over $100 million from several dozen of his clients, while misrepresenting that their accounts had grown to approximately $275 million in value;
  • An injunction for a client charged with fraud by the public company to whom she had sold her energy consulting business, which permitted her to sell millions of dollars of restricted stock she received in the disputed merger, a victory that was followed by a seven-figure settlement payment reported in the company’s next SEC filing;
  • Internal investigations for private companies of alleged misconduct by officer/shareholders; and

  • Successfully negotiated multiple highly contentious divorces of long-term business relationships often without litigation.

rEal estate LITIGATION

  • A seven-figure judgment after trial, affirmed on appeal, on a building owner’s claims against both a contractor and its principals;

  • Summary judgment for a commercial real estate owner holding that a property sale contract was void and of no effect under an attorney modification clause, where the would-be purchaser's attorney proposed modifications to the contract after it was signed and the owner did not accept the proposed changes;

  • A negotiated victory for a national hotel operator in a lease dispute with its landlord. After taking over the case from prior counsel, we amended the complaint to add claims that the landlord and its affiliate had breached the lease's territorial exclusivity covenant. We then sought discovery on the affiliate’s profits from improperly competing with our client. After we obtained court orders requiring defendants to comply with that discovery, the landlord reversed its longstanding opposition to extending the lease and settled the dispute by entering into a 50-year lease that ceded operational control of the property to our client;
  • The removal of an illegal billboard that stalled completion of a shopping center development, after the Illinois Appellate Court affirmed the trial court’s entry of summary judgment in our client’s favor; and
  • Court orders dismissing fraud and contract claims brought by investors against a real estate development partnership, followed by the plaintiffs’ voluntary dismissal of the action with prejudice.

healthcare litigation

  • Represented a medical device provider in payment claims against a leading insurer that resulted in a landmark ruling by the U.S. Fifth Circuit Court of Appeals sustaining our client’s fraud and tort claims against ERISA-preemption defenses;

  • Favorably settled claims by and against a revenue cycle management company arising from the early termination of its multi-year collection contract with a large regional physician group;

  • Successfully represented healthcare consultants in multiple civil, bankruptcy and investigative proceedings relating to disputed fees paid to physicians by testing laboratories; and

  • Successfully resolved disputes between the two 50% owners of a healthcare benefits agency and online exchange.

Energy Disputes

  • An $18 million settlement, reached during arbitration, in favor of a coal purchaser arising from a producer’s failure to deliver low-priced coal as market prices rose;
  • An arbitration award and federal court judgment in favor of subsidiaries of a publicly-held energy company, restraining frivolous multi-million dollar litigation in Guatemala, which freed our client to sell its assets in that country;
  • An arbitration award in favor of a retail gas supplier awarding it every dollar it sought in damages, attorney’s fees and arbitration expenses on its claim to enforce two unsigned contract amendments; and
  • An arbitration award in favor of a retail power seller denying a commercial customer’s claim for purported overcharges and awarding our client all of its arbitration expenses.

Steve also has substantial experience in defending antitrust class actions and consumer fraud claims, and in employment, non-compete/non-solicit, trademark, IP licensing, and transportation industry disputes.
