INDIANAPOLIS (AP) _ The state's push for tougher regulations on an Indiana Planned Parenthood clinic that provides only drug-induced abortions could spark a new court fight as a revised law takes effect next month.

The Republican-dominated Legislature this spring approved changes to a 2013 law that required the Lafayette clinic to meet the same standards as surgical abortion clinics in order to offer abortion medications. A federal judge blocked that law, ruling it violated equal protection rights by treating the clinic differently than any physician's office providing the same medications.

Lawmakers revised the law this year to drop the references to doctors' offices. That has opened the possibility that the state will seek an end to the injunction.

A spokesman for the attorney general's office says the state is reviewing its options. <br />
