GIR Awards 2018

Mayer Brown was honored by Global Investigations Review for its role in the landmark Société Générale settlement, a case recognized as the “Most Important Development in Investigations.”

“‘[Hank] has a memory like no one I’ve met before; he retains a tremendous amount of information and can recall it immediately.’”

Chambers USA 2017 (as quoted by a client)

Henninger "Hank" Bullock serves as head of Mayer Brown's Litigation & Dispute Resolution practice in New York. He is an experienced litigator who counsels clients in the financial-services and life-sciences sectors. Hank has handled hundreds of complex disputes in state and federal courts throughout the United States at both the trial and appellate levels. He also has significant experience in large multidistrict litigations, serving as liaison counsel for defense groups. These experiences have resulted in him being recognized by many prestigious publications, including Chambers USA, Legal 500, Benchmark Litigation's 2017 and 2016 "Under 40 Hot List," LMG Life Sciences' "Life Sciences Star" list (2013-2018) and Law360's 2014 "Product Liability MVP" list.

Hank provides defense against all types of claims for life-sciences clients, including product-liability, licensing and supply disputes. In the product-liability sphere, he has served as lead national counsel for brand-name pharmaceutical companies, devising strategy and coordinating the defense of thousands of lawsuits across multiple jurisdictions. Hank also has extensive appellate experience in this area, having successfully handled cases before United States Court of Appeals for the Fifth, Sixth, Eighth, Ninth, Tenth and Eleventh Circuits, the Missouri Supreme Court and the Missouri Court of Appeals, the Iowa Supreme Court and the Iowa Court of Appeals, the Georgia Court of Appeals and the Florida First District Courts of Appeal. Many of Hank's recent successes resulted in Law360 naming Mayer Brown a “Consumer Protection Group of the Year” in both 2018 and 2017 and a "Life Sciences Group of the Year" in 2017.

Financial-services clients, including major commercial and investment banks, hedge funds, broker-dealers and commodity-trading firms, rely on Hank to defend them in lawsuits, government regulatory proceedings and internal investigations involving securities, commodities, derivatives and foreign exchange products. His representation encompasses customary disputes over regulated financial products, as well as highly sophisticated and unregulated structured finance-and-derivative transactions. Hank has been particularly successful in defending financial institutions and their officers and directors in claims of fraud or misrepresentation associated with the trading of complex financial assets. Hank’s recent work for financial institutions has led to Law360 recognizing Mayer Brown as a “Banking Group of the Year” in 2018 and 2017.

In addition, Hank represents clients from various business sectors in complex contract and tort matters.
