BOISE - Idaho voters approved a proposed amendment to the Idaho Constitution Tuesday night, giving the state's lawmakers more say in agency rulemaking.

HJR 5 passed with 56 percent of the vote, with 98 percent of precincts reporting Wednesday morning.

The amendment allows the Idaho Legislature to reject or change rules created by executive branch agencies. The process is known as a legislative veto.

After a similar proposal was struck down two years ago, sponsors came back in full force, raising more than $100,000 to support the only constitutional amendment on the November ballot. Campaign finance reports showed that Citizens for HJR 5 received donations almost exclusively from Republican lawmakers and lobbying groups.

Prominent state officials were split on the proposed amendment as Election Day approached. Gov. C.L. "Butch" Otter and Attorney General Lawrence Wasden both opposed it, while Lt. Gov. Brad Little, and most legislators came out in favor of the proposal.
