Motion to quash

Verizon notified Harrison by letter that the company had received a subpoena "requiring the production of records" associated with his IP address.

Verizon told him to direct questions to the party that issued the subpoena: the law firm Dunlap Grubb Weaver. Verizon told Harrison that unless it received "a motion to quash" the subpoena by May 13, 2010, the ISP would turn over the information.

Harrison said he wasn't given much time. The letter may have been dated April 30, but it wasn't postmarked until May 5, and he didn't receive it until May 8, he said. That left him a week to decide what to do.
