before Judge McCullough, we find nothing in the record to establish that the Arbogasts brought this to Judge Marko-vitz’s attention. We conclude, considering the circumstances, that it was incumbent upon them to do so before they can assert that such a hearing was wrongly withheld. We therefore reject this ground for appeal also. CONCLUSION For the foregoing reasons, the judgment of the district court is AFFIRMED. ** The Pennsylvania Supreme Court has instructed that "[ojfficial comments are to be given weight in the construction of statutes,” Lessner v. Rubinson, 527 Pa. 393, 398 n. 4, 592 A.2d 678, 680 n. 4 (1991), a principle that is derived from Pennsylvania statutory law, 1 Pa. Cons.Stat. § 1939. See also McGowan v. University of Scranton, 759 F.2d 287, 298 & n. 14 (3d Cir.1985)
