John J. Byron



Since joining the firm, John has focused his practice on securities litigation and enforcement and other complex litigation matters.  John has also spent significant time assisting clients with internal and government investigations into alleged securities violations and alleged bribery and corruption and helping clients conduct anti-bribery and corruption due diligence in connection with business transactions or other business arrangements. 

John's experience extends across a diverse range of industries, including oil and gas, power, real estate, insurance, financial services, telecommunications, transportation, and retail.  His litigation experience includes defending companies in Securities Act, Exchange Act, Texas Securities Act, RICO, Robinson-Patman Act, TVPA, ATCA, fraudulent transfer, and fiduciary duty cases. 

In 2013 and 2014, John spent six months in Norton Rose Fulbright's London office where he worked with the Business Ethics and Anti-Corruption group. Both in London and in Houston, John has advised clients on bribery and corruption risk and worked on multi-jurisdictional bribery and corruption investigations.

In 2015 and 2016, John participated in the Firm's attorney loan program where he spent one day a week for twenty weeks prosecuting cases on behalf of the City of Houston.  As part of that program, John prosecuted approximately ten cases to jury verdict. 

Most recently, John has worked with companies and their boards of directors to respond to activist shareholders and advised companies on issues related to business and human rights risk.  In addition, John founded and co-leads the Emerging Leaders in Compliance and Investigations Network, which brings together in-house lawyers to foster thought leadership on compliance and investigative issues.
