   MEMORANDUM

Elmer and Joan Thomassen appeal pro se the district court’s order denying their motion to vacate its renewal of judgment orders which the district court had granted due to the Thomassens’ 1979 tax deficiency. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo the legal question whether the discharge in bankruptcy affected the judgment lien, see United States v. Hemmen, 51 F.3d 883, 886 (9th Cir.1995), and we affirm.

The Thomassens contend that the 1979 judgment orders, which were renewed in 1989, were discharged by their 1991 bankruptcy discharge order. We disagree. Because the renewal of judgment orders were limited to the government’s in rem rights against its pre-petition property interests, cf. Isom v. United States, (In re Isom), 901 F.2d 744, 746 (9th Cir.1990), the district court properly denied the Thomassens’ motion to vacate the renewal of the judgment orders.

We also disagree with the Thomas-sens’ contention that Judge Real should have been disqualified from this case. The Thomassens failed to show that Judge Real was biased against them from an extrajudicial source. See United States v. Sibla, 624 F.2d 864, 868 (9th Cir.1980).

The Thomassens’ other contentions are without merit.

AFFIRMED.
