A defendant was convicted of corruption of minors in Pennsylvania, and was ordered as part of his probation to take polygraph examinations. A year ago he failed an examination, and was taken back to court. The probation officer accused him of being in denial, and he was required by the court to engage in a counseling program. Now he's been ordered to take another polygraph examination. If they say he has failed the examination again, can they punish him another time?
