The issues of how much computer data federal agents can seize under a warrant, how long they can hold onto it and what they can do with it will be taken up by the full U.S. Court of Appeals for the Second Circuit Wednesday.

In a rare en banc sitting, the full circuit will hear a case involving investigators who seized hard drives that held information beyond the scope of a search warrant and then used that information later to obtain a second warrant on an unrelated criminal case.
