Before WOLLMAN, McMILLIAN, and RILEY, Circuit Judges.

PER CURIAM.

     Alvena and Joseph Long, and intervenors Laura Wagster and Linda Davis (the
Longs), appeal following the district court’s1 final judgment in a condemnation action


      1
       The Honorable Charles A. Shaw, United States District Judge for the Eastern
District of Missouri.
                                           -2-
brought by the United States, in which the Longs counterclaimed for interest, costs,
and fees. The district court concluded it lacked subject matter jurisdiction over the
counterclaim, and alternatively held that the government was entitled to summary
judgment on the merits of the counterclaim. The district court later entered a final
order of condemnation. The Longs now appeal the court’s ruling on their
counterclaim.

       The Longs raise no argument, in either their opening or reply briefs, concerning
the district court’s ruling that it lacked jurisdiction over their counterclaim. Rather,
they have limited their briefing to the merits of their claim. The district court also
noted that the Longs did not respond to the government when it raised the issue
below. In these circumstances, we conclude the Longs waived any challenge to the
district court’s finding of no jurisdiction. See XO Mo., Inc. v. City of Maryland
Heights, 

, 1025 (8th Cir. 2004) (by failing to raise issue on appeal,
party waived challenge to court’s determination on issue); cf. United States v.
Century Healthcare Corp., 

, 1518 n.2 (10th Cir. 1996) (appellate court’s
duty to consider obstacles to subject matter jurisdiction does not affect court’s
discretion to decline to consider waived arguments that could have supported
jurisdiction).

       Because the Longs have conceded a lack of subject matter jurisdiction over
their counterclaim, we do not reach the merits, and we affirm. See 8th Cir. R. 47B.
