Prosecutors are urging a federal judge to affirm their right to use a warrant to seize an off-shore email account maintained by Microsoft.

Countering claims by the computer giant and other cloud service providers that digital information it stores on a server in Dublin, Ireland is off-limits to U.S. law enforcement, the government filed papers late Wednesday saying the warrant does not violate the presumption against extraterritorial application of U.S. laws because it is not, in fact, extraterritorial.
