Is a polygraph test inadmissible in court?

Answer:

I think no.

1980 - United States v. Roberts
The prosecutor had told the grand jury unequivocally that polygraph results were inadmissible in a court of law and the court called her on the carpet and stated that her statememnt was false and said "The Court dissapproves of the prosecutor's bold statement to the Grand Jury that polygraph evidence is inadmissible at trial. Such statements are absolutely untrue. The Ninth Circuit has held that polygraph evidence is admissible within the trial court's discretion."
As current law stands it is up to the trial judge as to how he or she will handle any motion to admit polygraph evidence.and Polygraph tests are regularly admitted as evidence in trials and they are also regularly rejected as evidence in trials....

However Legally in all 50 States of the US you can refuse to submit to a polygraph test and the fact that you refused the test can't be used against you in a court of law..But if you take the test it could be used against you if the trial judge decides to allow it.
