The technical term is that it is "excluded" upon a motion to suppress made by the lawyer for the accused. It is based on the constitutional requirement that "?no [person] can be deprived of life, liberty, or property, without due process of law" (Fifth Amendment to the Constitution, applied to the states by 14th Amendment). A technical error in a search warrant made in good faith will not cause exclusion of the evidence obtained under that warrant. In 1995 the U. S.
