No. Not the sole results of the polygraph. However, they can be used by law enforcement as an investigative tool. The results that are produced by those interviews, if investigation substantiates them, ARE admissable.
Lie detector test is one of the due process investigation of the suspect. but this is not the basis of the case if the suspect is guilty of the charges.
A court can order you to take one, yes.
If you are not guilty or you know how to beat a lie detector then yes.ADDED: (in the US) The results of such a test are NOT admissibile in court - however - the police CAN use them to assist in conducting their investigations.
Lie detector tests are not 100% accurate and although given by law they are not admissibly in a court of law and using a lie detector is not used for public use; therefore it would not make any point for your wife to take a lie detector test. Hypothetically, if your wife did cheat she would probably decline taking the test.
