The state population is 27% Black, but the districts are drawn so that white voters are a majority in six of Alabama's seven congressional districts.
The judges said they were reluctant to get involved in a task typically left to the states.
In Georgia on Tuesday, a judge began hearing a no-jury trial on whether the GOP-controlled state legislature wrongly drew congressional and state legislative lines to dilute Black voting power.
Louisiana – which has a Republican state legislature and a Democratic governor – has a population that is about one-third Black.
But five of the state's six congressional districts are majority-white.
