Abortion regulation encompasses a variety of laws and policies that govern the legality, accessibility, and funding of abortion services. These regulations can vary significantly from state to state, influenced by legislative actions, court decisions, and voter referendums. The federal framework established by the Supreme Court decisions, primarily Roe v. Wade (1973) and Planned Parenthood v. Casey (1992), set broad parameters for these regulations, allowing states considerable leeway within those bounds. Over the years, amendments and new rulings have modified the scope of abortion rights and regulations, reflecting ongoing legal, ethical, and political debates.
