With Friday's landmark ruling, Missouri's "trigger law" effectively banning abortion is now in effect. Missouri was one of more than a dozen states with so-called trigger laws that will now outlaw abortion after the Supreme Court overturned the precedent set in Roe v. Wade.Missouri’s trigger law was tacked onto another bill as an amendment. That other bill is a ban on abortions at eight weeks. With the Supreme Court's decision Friday to overturn Roe v. Wade, that eight-week ban becomes null and void -- any abortion in the state of Missouri is now illegal regardless of how far along the pregnancy is.Missouri Attorney General Eric Schmitt tweeted Friday morning that with an AG opinion signed shortly after the release of the Supreme Court decision, Missouri becomes the first state in the country to effectively end abortion. Missouri Governor Mike Parson also signed the "Right to Life of the Unborn Child Act.""Nothing in the text, history, or tradition of the United States Constitution gave un-elected federal judges authority to regulate abortion. We are happy that the U.S. Supreme Court has corrected this error and returned power to the people and the states to make these decisions," Gov. Parson said in a statement.This act specifically prohibits doctors from performing abortions unless there is a medical emergency. It also makes anyone who performs an abortion outside of a medical emergency, or who indices a non-medical emergency abortion criminally liable, and subjects a doctor's license to suspension. “They have been chipping away at the right of abortion, but they haven't been able to outright ban it, which is the game-changer of this trigger law," said UMKC law professor Yvette Lindgren in an interview earlier this year. Lindgren said this ban may also affect women seeking health care other than abortions."Some very effective forms of contraception could become criminalized,” Lindgren said.Some birth control methods, specifically the morning after pill and IUDs, permit an egg to be fertilized but prevent the egg from implanting in the uterus. These could also become restricted if the supreme court overturns its 1970s decision."If life begins at fertilization, then means birth control that prevents implantation and causes the body to schlep off fertilized eggs before they get implanted, that would be considered an abortifacient,” Lindgren said.In-vitro fertilization practices would also be impacted. Under Missouri law, Lindgren says fertility doctors wouldn't be able to implant more than one embryo.It would make an already long and expensive process longer and more costly."People who are coming in for lots of other types of health care or are using contraception are going to be ensnared in this prohibition," Lindgren said.
