“EPIC joined eight civil liberties organizations to submit a “friend of the court” brief (38 pages, PDF) in Forensic Advisors v. Matrixx Initiatives, a case before the Maryland Court of Special Appeals in which a pharmaceutical company is attempting to force a newsletter publisher to disclose his subscriber list. The company wants to use the list in connection with a law suit it filed against numerous unidentified people who posted derogatory comments about the company on Internet discussion boards. The brief argues in favor of protecting the list under a Maryland law that protects journalists’ sources. It also argues that the list is protected under the First Amendment, since disclosure of the list would deter readership and violate constitutionally established privacy rights.”
