Where supervision of an offender is being administered pursuant to the Interstate Compact for Adult Offender Supervision, the appropriate judicial or administrative authorities in this State shall notify the Compact Administrator of the sending State whenever, in their view, consideration should be given to retaking or reincarceration for a parole or probation violation. Prior to the giving of any such notification, a hearing shall be held within a reasonable time as to whether there is probable cause to believe that the offender has violated a condition of his parole or probation, unless such hearing is waived by the offender by way of an admission of guilt. The appropriate officer or officers of this State shall as soon as practicable, following termination of any such hearing, report to the sending State, furnish a copy of the hearing record, and make recommendations regarding the disposition to be made of the offender.
