Most abortions would be banned in Utah under a proposal at the state Legislature. Abortion-rights advocates say it would create fear and uncertainty even though it wouldn’t be enforced unless the legal landscape changes. The proposal would make it a felony to perform an abortion except in cases of rape, incest or serious threat to the health of the mother. The measure contains a so-called trigger clause, so it wouldn’t go into effect unless the U.S. Supreme Court overturns Roe v. Wade, the landmark 1973 case that legalized abortion in the country.
