SPRINGFIELD, Mo. (AP) — Nipples can be exposed in Springfield while the American Civil Liberties Union makes its case that a new ordinance violates the Constitution and state law.

A judge granted a temporary injunction in the case Friday in federal court. It leaves in place a narrower indecent exposure ordinance.

The issue heated up last summer.

That’s when two women affiliated with an organization called “Free the Nipple” held a topless rally to dispute a city ordinance on exposure. After that rally, the city council passed a stricter ordinance that requires most of the female breast and all buttocks to be covered.

The ACLU argues that the new ordinance criminalizes free expression by women and subjects them to “inferior legal status.”

Besides the injunction, proceedings on the case have been stayed for 60 days.
