First Cash Financial Services v. Doe [1]

First Cash Financial Services, a Texas-based company operating a chain of pawn shops and cash checking services, sued a John Doe defendant [2] in Texas state court.  The complaint alleged breach of contract arsing out of critical statements about the firm's accounting practices posted to Fast Cash's Yahoo! Finance message board [2]. 

After obtaining permission of the Texas court, First Cash asked a California state court to issue a subpoena requiring Yahoo to provide identifying information for the anonymous poster.  A clerk of the court issued the subpoena, and the anonymous poster filed a special motion to strike the action (including the subpoena) under California's anti-SLAPP statute [3].  According to EFF [4], the California court denied the motion to strike, presumably allowing the subpoena to be enforced.

The CMLP was not able to find any information about what happened to the case upon its return to Texas state court.
