Is the use of lie-detector tests legally valid in the administration of justice

1. Lie-detector tests, also known as polygraph tests, are not universally admissible in court as evidence due to their unreliability and potential for inaccuracies. 2. Although some jurisdictions allow lie-detector test results to be used as evidence, they are often viewed as supplemental rather than conclusive. 3. The admissibility of lie-detector test results varies by jurisdiction, with some courts considering them to be inadmissible due to the lack of scientific consensus on their reliability. 4. In the United States, the results of lie-detector tests are generally not admissible in federal courts, except under specific circumstances agreed upon by both parties. 5. Ultimately, the use of lie-detector tests in the administration of justice is limited and subject to scrutiny due to their questionable reliability.
