The state Supreme Court last week issued an order keeping the proposed state constitutional amendment – called Amendment 3 – on the Nov. 5 ballot. The judges’ decision came hours before a deadline to finalize the ballot and they didn’t explain their reasoning at the time.

The Missouri Supreme Court narrowly upheld an abortion rights measure on November ballots by a 4-3 vote earlier this month, according to a judicial opinion documents released Friday.

Missouri was the first state to enact a near-total ban on abortion. This November, Missouri voters have the chance to reverse it with Amendment 3, which would guarantee the right to an abortion until fetal viability.

Abortion rights remained on Missouri’s Nov. 5 ballot by the slimmest of margins, according to opinions released Friday by the Missouri Supreme Court.
