In the 1973 case of Roe v. Wade, the US Supreme Court ruled that laws banning abortion violated the US Constitution. The Texas abortion laws, articles 1191–1194, and 1196 of the Texas penal code, made abortion illegal and criminalized those who performed or facilitated the procedure. Prior to Roe v. Wade, most states heavily regulated or banned abortions. The US Supreme Court decision in Roe v. Wade secured women's rights to terminate pregnancies for any reasons within the first trimester of pregnancy. It also sparked legal discussions of abortion, fetus viability and personhood, and the trimester framework, setting a landmark precedent for future cases including Webster v. Reproductive Health Services (1989), Planned Parenthood v. Casey (1992), and Stenberg v. Carhart (2000).
