The US Coast Guard 2012 Annual Report to the American Bar Association mentions, amongst a wealth of information about the service's activities, that Coast Guard attorneys have facilitated the development of principles for member governments wishing to participate in IALA-NET, an AIS (Automatic Identification System).
