Pa. O.C.R. 310.A
The Chester County juvenile probation office ("probation office") is hereby authorized to impose reasonable pre-adjudication conditions on all juveniles against whom Petitions have been filed or are pending under the Juvenile Act, including a requirement that the juvenile submit to a urinalysis to determine controlled substance use. Such conditions shall be from among those previously approved by the court to protect the public, maintain the competencies of the juvenile and/or assist the probation office in recommending an appropriate disposition in the event of an adjudication of delinquency. Any juvenile, or attorney representing a juvenile, may seek emergency relief from the juvenile court supervising judge if any pre-adjudication condition imposed by the juvenile probation office is deemed to be unreasonable. Any juvenile who refuses, explicitly or implicitly, to comply with any pre-adjudication condition, including the refusal to submit to a urinalysis, without providing an adequate medical or other extraordinary reason to justify that refusal, shall be presumed by the court to have failed to successfully comply with that condition. In no event shall the court consider a juvenile's compliance or failure to comply with a pre-adjudication condition when it determines whether the juvenile committed any charged delinquent act.
