Chris Johnstone represents clients facing investigations and enforcement actions by the Department of Justice (DOJ), Securities and Exchange Commission (SEC), and state Attorneys General. As a resident of the firm’s Palo Alto office, Mr. Johnstone has worked with companies throughout Silicon Valley on high-profile internal investigations and complex litigation. 

Mr. Johnstone has significant experience defending clients in SEC enforcement actions. He was a key member of the WilmerHale trial team that prevailed on all ten claims brought by the SEC against two former executives of Thornburg Mortgage. During that case, Mr. Johnstone presented more than a dozen oral arguments and managed years of litigation. More recently, he served as co-lead counsel for an individual in an SEC enforcement action in the US District Court for the Southern District of New York. Earlier in his career, Mr. Johnstone represented the former CFO of a Silicon Valley tech company in an SEC enforcement action in the US District Court for Northern District of California.

Mr. Johnstone has also played a leadership role in major antitrust cases. Last year, he represented a foreign manufacturer of capacitors in a class action lawsuit seeking more than $1 billion in damages. During that case, Mr. Johnstone deposed a former US Attorney and successfully excluded him from testifying at trial as an expert. In 2018, Mr. Johnstone was a key member of the WilmerHale trial team that obtained the acquittal of Rohan Ramchandani, a former foreign exchange (FX) trader charged with criminal violation of the Sherman Act in the US District Court for Southern District of New York. 

In his pro bono practice, Mr. Johnstone represents individuals facing criminal charges in the US District Court for the Northern District of California. He has repeatedly obtained successful results on behalf of clients facing decades in prison.

Before entering private practice, Mr. Johnstone served as a law clerk for two years for the Honorable Shirley Wohl Kram in the US District Court for the Southern District of New York.

Mr. Johnstone serves on the Hiring Committee for the firm’s Northern California offices.
