The U.S. Supreme Court reaffirms the right to abortion while permitting new state restrictions. In Planned Parenthood v. Casey, the Court finds that Roe v. Wade established a “rule of law and a component of liberty we cannot renounce.” It also adopts a new standard for evaluating abortion restrictions. It had required evidence of a “compelling” state interest. Now, it will allow requirements that do not present a “substantial obstacle” to a woman seeking an abortion. The Court upholds Pennsylvania’s 24-hour waiting period and informed consent rules.
