A California professor suing his students who recirculated his exams plans to issue a subpoena to identify the perpetrators.

Attorney Marc Hankin, who is representing David Berokvitz, a business professor at Chapman University, said on March 15 that the professor will subpoena resource-sharing website Course Hero as part of the lawsuit in an effort to release the names of and IP addresses associated with the students responsible for posting the documents, according to the Orange County Register.
