(AP) — A federal appeals court is set to hear arguments in a case involving boundaries for a Mississippi State Senate district with just weeks to go before an Aug. 6 primary.

A federal judge ruled in February that boundaries for Senate District 22 illegally dilute black voting strength. The Legislature redrew the lines in March.

But Mississippi’s governor and secretary of state want the old boundaries reinstated. They’re asking the 5th U.S. Circuit Court of Appeals to immediately overturn the district judge and re-open qualifying for the old district.

Others say the judge’s order — and the new boundaries — should stand. They argue a change now would needlessly disrupt the race.
