PIERRE, S.D. (KELO.com) – Major business and media groups in South Dakota have jointly filed suit against a ban on out-of-state money to fund ballot question campaigns.

Their lawyer is former State Attorney General Marty Jackley.

He says the ban violates the Commerce Clause in the Constitution.

IM-24 was approved by the voters in November and was scheduled to take effect July 1.

This is familiar ground to Jackley. While he was State Attorney General he argued the Wayfair case before the U.S. Supreme Court. That involved out-of-state companies. He says the same thing here, only out-of-state political groups.
