The Idaho Supreme Court has rejected a new law designed to make it harder for voters to get initiatives on the ballot, saying the legislation was so restrictive that it violated a fundamental right under the state’s constitution.

The ruling issued Monday was a win for Reclaim Idaho, a group that successfully sponsored a Medicaid expansion initiative three years ago and that is now working to qualify an initiative for the ballot that aims to increase public education funding.

Idaho Speaker of the House Scott Bedke said in a prepared statement that members of the House Republican Caucus were disappointed by the ruling. He said the law would have increased voter involvement, “especially in the corners of the state too often forgotten by some.”

Reclaim Idaho co-founder Luke Mayville said the ruling means thousands of Idaho residents are “breathing sighs of relief.”

“Nearly every time in our history that our legislature attempted to eliminate the initiative process, either the governor or the courts stepped up to protect the rights of the people. Today’s decision adds a new chapter to that history, and future generations of Idahoans will look back on the court’s decision with gratitude,” Mayville said in a prepared statement.

The high court’s opinion written by Justice Gregory Moeller was unanimous in its main conclusion — that the law should be overturned — though two of the justices said they would have gotten at the same conclusion in slightly different ways.

“The ability of the legislature to make laws related to a fundamental right arises from the reality that, in an ordered society, few rights are absolute,” Moeller wrote. “However, the legislature’s duty to give effect to the people’s rights is not a free pass to override constitutional constraints and legislate a right into non-existence, even if the legislature believes doing so is in the people’s best interest.”

The case pitted the rights of voters to enact and repeal laws against the power of the state Legislature to shape how ballot initiative efforts are carried out. The new law, which passed earlier this year, required signature-gatherers to get 6% of registered voters in each of Idaho’s 35 legislative districts within a short time span. Opponents said it made Idaho’s initiative process the toughest in the nation, rendering such efforts virtually impossible to achieve. But supporters said the law would protect people with less popular political opinions from being overrun by the majority.
