Super Lawyers - Massachusetts "Rising Star" - Top Rated Business Litigation Attorney (2010 & 2011)

Phi Beta Kappa

Jack I. Siegal is a Partner in the Boston office of Gordon & Rees and is a member of the Commercial Litigation practice group. He is a trial lawyer with over eighteen years of experience. Mr. Siegal routinely handles securities litigation, complex commercial disputes, and white collar criminal matters. His philosophy is to focus creatively on the core of the dispute, and to spurn the inefficiencies and attorney battles that escalate client costs and provide zero case value. Mr. Siegal has numerous federal and state bench and jury trials to his credit.
Most recently, Mr. Siegal has obtained dismissal of 1933 Securities Act claims against underwriter defendants in state court in the wake of the Supreme Court’s Cyan decision limiting the removal of such claims to federal court.  Mr. Siegal has also served (and continues to serve) as lead counsel on several federal grand jury investigations concerning alleged financial crimes.  Mr. Siegal is experienced litigating shareholder matters in the Chancery Court in the State of Delaware.
A seasoned trial lawyer, Mr. Siegal conducted a six-day trial in bankruptcy court to deny a Chapter 7 debtor a discharge on behalf of his client, the debtor’s largest creditor with a claim in excess of $20 million. His client financed one of the debtor’s luxury condominium development projects in the Boston-area, which failed for a variety of reasons. The debtor personally guaranteed the financing, but engaged in a fraudulent scheme both to procure the financing and prevent his client from collecting on the guaranty and other collateral. After the debtor was in bankruptcy, Mr. Siegal was hired to ensure that the $20 million debt would not be discharged. Further, during the course of case, Mr. Siegal exposed the debtor’s fraud on the court and his creditors in connection with his bankruptcy disclosures, and, as a result, obtained sanctions against the debtor. 
Mr. Siegal also helped an investment partnership obtain a favorable ruling from the Ninth Circuit Court of Appeals which allowed the partnership to continue prosecuting its lawsuit against a prominent national law firm which allegedly helped steal the partnership’s funds in connection with a bogus pre-IPO sale of Facebook stock. See ESG Capital Partners, LP et al. v. Venable LLP et al., No. 13-56684 (9th Cir. July 11, 2016).
Mr. Siegal is and has been lead counsel in several FINRA arbitrations none of which to date have resulted in an unfavorable client result.  Mr. Siegal counts as his clients hedge funds and family offices.
