Many fields of law can today be described as fluid and fast-changing. Military law, however, would seem to hold a paramount title to such a description. For instance, before one's eyes military jurisdiction can appear and then disappear in the same case as fundamental principles are judicially altered. Insofar as matters of evidence are concerned, this fluidity is especially discernable-- as will be obvious from an examination of some opinions rendered by the Court of Military appeals during the past decade.
