Earthjustice sued for a temporary restraining order of tests because the navy did not comply with the MBTA, although they did comply with the other environmental laws. As a result, a law was introduced by congress (H.R. 4546) to amend the Migratory Bird Treaty Act of 1918 to make it lawful for the Department of Defense to "take migratory birds during a 'military readiness activity.'" (Readiness activities are defined as all training activities and military operations related to combat and the testing of equipment for combat use.) The record in congress noted that "A recent federal court ruling indicated that the Navy had violated the Migratory Bird Treaty Act by incidentally taking migratory birds without a permit during training exercises near Guam. The House report indicates that the exemption provision is intended to address the lack of permit authorization for incidental takings, so that essential training exercises may proceed. It appears that the language used in the bill would not authorize the issuance of permits, but more broadly would state that the part of the Migratory Bird Treaty Act that articulates unlawful behavior does not apply to a military readiness activity.
