Last month, Missourians voted to add the right to abortion until viability into their state constitution—making their state one of ten to enshrine abortion rights since the Supreme Court overturned Roe v. Wade.

But simply having the constitutional right to abortion does not alone change anything on the ground: The courts must enforce this right by affirming that anti-abortion laws violate states’ newly amended constitutions. A ruling this week by a Missouri judge shows just how fraught it is to depend on the courts for abortion access—even after the people, by popular vote, demand it.

Within 24 hours of the November election where Missouri voters passed the state’s abortion-rights amendment, Planned Parenthood sued to ask the courts to enforce this change. On Friday, a state judge weighed in for the first time: She temporarily blocked the state’s near-total abortion ban. But she left in place several anti-abortion laws that will continue to prevent abortion providers from serving patients.
