Roe v. Wade 410 U.S. 113
Issue: Abortion/Women's Rights
"In the first trimester of pregnancy, the state may not regulate the abortion decision; only the pregnant woman and her attending physician can make that decision. In the second trimester, the state may impose regulations on abortion that are reasonably related to maternal health. In the third trimester, once the fetus reaches the point of “viability,” a state may regulate abortions or prohibit them entirely, so long as the laws contain exceptions for cases when abortion is necessary to save the life or health of the mother."
