A judge Tuesday refused to lift the stay on the $151 million judgment against Nebraska in a nuclear waste lawsuit.
A regional group sued Nebraska for refusing to build a regional waste dump within its borders.
U.S. District Judge Richard Kopf had been asked to lift the stay or make Nebraska post a bond in the case.
He refused both requests.
Lawyers for the group argued that the state was no longer entitled to a stay while the judgment is appealed.
That's because the Legislature recently passed a law that reduced the interest rate Nebraska pays on judgments.
The dump was to hold low-level radioactive waste from Nebraska, Kansas, Arkansas, Oklahoma and Louisiana.
