1. According to Swiss law, the use of a lie detector, of narco-examination or of a truth serum as a method to establish the truth is not admissible on a constitutional basis. As a result, the CAS does not deem admissible as evidence a deposition based on a lie detector test. The CAS may take into consideration the declarations of persons in front of a polygraph as mere personal statements rendered by a party to the dispute and by a witness, with no additional evidentiary value whatsoever given by the circumstances that they were rendered during a lie detector test.
