A U.S. judge has ordered Google to comply with search warrants seeking customer emails stored outside the United States, diverging from a federal appeals court that reached the opposite conclusion in a similar case involving Microsoft Corp.

U.S. Magistrate Judge Thomas Rueter in Philadelphia ruled on Friday that transferring emails from a foreign server so FBI agents could review them locally as part of a domestic fraud probe did not qualify as a seizure.

The judge said this was because there was "no meaningful interference" with the account holder's "possessory interest" in the data sought.
