Abortion has been a hotly contested political issue since the mid 1960s, when states began liberalizing their abortion laws. Recent Supreme Court rulings, such as Rust vs. Sullivan, the retirement of two liberal Supreme Court justices and the battle over Louisiana's abortion legislation have created new fervor on both fronts of the battle. All health care providers who care for women need to be cognizant of the current abortion laws and the factors that influence the abortion decision. These factors include the different levels of health risk and financial implications posed by continued pregnancy or abortion. Historically, numerous court cases have influenced women's health care, and reviews of several significant cases are provided. The Webster vs. Reproductive Health Services decision was the first case that directly challenged the Roe vs. Wade decision. The Webster decision enables states to have greater authority in writing their own abortion laws. Individual state laws can vary greatly, so it is vitally important for providers to know and understand the laws of their state.
