Representative Matters

As an attorney

  • Member of trial team in in United States v. Kaluza, where our client was acquitted of all charges stemming from the BP Deepwater Horizon oil spill. Jon persuaded the court to exclude a co-defendant’s plea agreement from evidence, leading to what the Wall Street Journal called “a critical moment“ in the case: the government’s primary witness providing candid testimony more favorable to the defense.
  • Member of trial team in Vantage v. Petrobras, an international arbitration in which the client faced allegations of both foreign bribery and violation of offshore safety and environmental regulations. Jon developed the technical side of the case, working with drilling experts to break down complex operational issues and show that blame for any deficiencies lay elsewhere. Following a 12-day hearing, the tribunal agreed, and the client was awarded $734 million in damages and interest.
  • Successfully represented multiple individuals in cases where the government either closed its investigation or proceeded against others, including:
    • A senior executive of an offshore drilling contractor under investigation by DOJ and SEC for potential violations of the Foreign Corrupt Practices Act.
    • The former CFO of an international oilfield services company under investigation by DOJ and SEC for alleged foreign bribery and accounting violations.
    • A small business owner under investigation by SEC for involvement in an alleged pyramid scheme and cryptocurrency fraud.
    • A Japanese executive under investigation by DOJ’s Antitrust Division for alleged price fixing.
    • A local hospital under investigation by two United States Attorney’s Offices for allegedly paying kickbacks for referrals.
    • The owner of an energy trading firm under investigation by CFTC for suspected violations of the Commodity Exchange Act.
