In Williams v. Pennsylvania Board of Probation and Parole, 134 Pa. Commw. 597, 579 A.2d 1369 (Pa. Cmwlth. 1990), the record contained no official verification of the date on which the Board learned that the parolee was available for transfer from a Georgia state correctional facility. On those unique facts, the Court noted that: "When the record contains no official verification, the 120-day period begins to run on the date that the Board could have obtained official verification." Id. at 601.
