Although the polygraph test has been in use in the United States for almost a hundred years, this technique is relatively new in UK & Ireland.  There is no court ruling on the admissibility of polygraph evidence in most countries. In the United States, most states permit polygraph test results to be used as evidence where parties have agreed to their admissibility before the examination is given, under the terms of a stipulation.  In one US state, New Mexico, polygraph evidence is admitted in the same way as other scientific evidence.
