U.S. District Judge Charles Kornmann struck down a ban on out-of-state contributions to ballot question committees recently passed by voters.

Kornmann found Initiated Measure 24 unconstitutional because it violates First Amendment rights to engage in political speech.

Additionally, Kornmann said the measure violates the Commerce Clause by interfering with the free flow of money between persons from another state and South Dakota committees.

The ruling is a permanent injunction that stops the planned implementation on July 1.

The state must now determine if it will appeal the decision to the U.S. Eighth Circuit Court of Appeals.
