From Reason:

This week, Judge Robert A. Lasnik of U.S. District Court for the Western District of Washington, in deciding on motions for summary judgment in that suit, State of Washington et al. v. U.S. Department of State et al., agreed that removing those files from the USML was unlawful based on the APA arguments (though not the 10th Amendment ones), and reversed the federal government’s choice to allow free distribution of the files.
As discussed in Lasnik’s decision, the federal government’s initial reaction to the states’ suit “justified the deregulation of the CAD files [that could help make weapons]…by pointing to a Department of Defense determination that the items ‘do not provide the United States with a critical military or intelligence advantage’ and ‘are already commonly available and not inherently for military end-use.'”
