Is a Polygraph Admissible?

Is a polygraph admissible in a criminal case?

Polygraphs can be used in court for certain proceedings but not for trial and not for the ultimate issue in a case. I have seen the polygraph used for violation of probation hears for sex offenders that refuse to admit they sexually assaulted the initial victim in the case. Often, we see people plea no contest in a sex case because the stakes are too high to fight the case. They are then ordered to go to sex offender counseling yet they refuse to admit guilt. They fail the class. The probation officer violates them. They go before the judge to get punished for the violation. The judge can consider the result of a polygraph in this instance, but it is not per se dispositive of the violation.
