Haslam signs 48-hour abortion waiting period law
Gov. Bill Haslam has signed into law a controversial bill requiring that women seeking abortions wait 48 hours between consultation with a doctor and the procedure.
The bill was passed by wide margins in the Tennessee House and Senate, the Times Free Press reports, after voters in November approved a constitutional amendment giving lawmakers the ability to pass it. The ballot measure was necessary because of a 2000 court ruling that found such laws unconstitutional.
