NEW ORLEANS- The federal judge who heard a challenge to Louisiana's abortion law says he'll rule in the case Tuesday.
    
The law requires doctors who perform abortions to be able to admit patients to a hospital within 30 miles. Supporters say it's meant to protect women's health. Opponents say the measure essentially would make it impossible for women to get abortions.
    
In a brief order Monday, District Judge John deGravelles of Baton Rouge said he was filing his proposed ruling under seal. He also says he's giving lawyers 24 hours to review it to make sure everything that is supposed to be confidential remains so.
    
He told lawyers they could tell their clients the gist of one section, warning them to keep that information secret until the entire ruling becomes official.
    
DeGravelles heard testimony in the case last June.
