Louisiana senators voted 31-1 Tuesday to approve a bill [SB181 materials] that would ban abortions at 15 weeks.
Mississippi approved [JURIST report] a similar 15-week abortion ban in March, drawing an immediate legal challenge.
An amendment to the Louisiana bill on the Senate floor means that the Louisiana bill would not go into law unless and until the Mississippi law is upheld by the courts.
The Louisiana bill must still face approval in the House. Current Louisiana law prohibits abortions after 20 weeks.
