The legality of abortion in the United States is subject to individual state laws. In 1973, Roe v. Wade made the first abortion case to be taken to the Supreme Court, which had made it federally legal. In 1992, Roe was partially overturned by Planned Parenthood v. Casey, which stated that states cannot place legal restrictions posing an undue burden for "the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus." In 2022, both Roe and Casey were overturned, and abortions are now subject to regulations based on state laws once again. Individual states can regulate and limit the use of abortion, some of which already have through the use of "trigger laws", which made abortion illegal within the first and second trimesters when Roe was overturned. Eight states-Alabama, Arizona, Arkansas, Michigan, Mississippi, Oklahoma, West Virginia and Wisconsin-still have pre-Roe abortion bans in their laws, which may be enforced too.
