First Cash Financial Services v. Yahoo! Inc. [1]

First Cash Financial Services, a Texas-based company operating a chain of pawn shops and cash checking services, obtained a subpoena from a California state court requiring Yahoo to provide identifying information for an individual who posted anonymous comments to Fast Cash's Yahoo! Finance message board [2].  Fast Cash sought the information in order to identify the John Doe defendant in a breach of contract action it had previously filed in Texas state court.  (For details, see the related database entry, First Cash Financial Services v. Doe [3].)  The anonymous poster intervened and filed a special motion to strike the action (including the subpoena) under California's anti-SLAPP statute [4].  According to EFF [5], the California court denied the motion to strike, presumably allowing the subpoena to be enforced.
