The Northern Marianas police chief, James Deleon Guerrero, wants a second challenge to the islands' law banning the ownership of handguns dismissed.
A former U.S. Army ranger Paul Michael Murphy is suing the police commissioner for $5 US million over the alleged confiscation of his firearms and ammunition in 2007.
Mr Deleon Guerrero asserts the U.S. District Court for the NMI lacks jurisdiction in this matter.
