State of Tennessee v. Gregory Pierce

We granted permission to appeal in this case to determine whether the trial court erred in considering the results of the defendant sex offender's polygraph examination when denying the defendant's request for probation. The polygraph examination was administered as part of the risk assessment report that is mandated by statute for all sex offenders seeking probation. Because polygraph examinations are inherently unreliable, we hold that trial courts may not consider polygraph examination results or any portion of a risk assessment report that relies upon polygraph examination results when imposing sentences. However, even excluding the polygraph examination results, the record in this case supports the denial of probation. Accordingly, the judgment of the Court of Criminal Appeals is affirmed in part and modified in part.
