A Missouri appeals court panel cleared the way Friday for voters to decide a November ballot initiative that could shake up of the state Legislature by requiring districts to be drawn to achieve "partisan fairness" and imposing new lobbying limits.

The ruling overturned a decision issued a week ago by a state judge who said the so-called Clean Missouri initiative violated the state constitution by addressing multiple topics.

The Western District appeals panel disagreed, ruling that the "multiple provisions all relate to a single central purpose: regulating the legislature to limit the influence of partisan or other special interests."

Republican-aligned attorneys for those opposing the measure said they would appeal to the state Supreme Court. But time is running short. Missouri law sets a Tuesday deadline to make changes to the Nov. 6. ballot. The state's high court previously turned down a chance to hear the case in place of the appeals panel.

As it stands, the measure would appear on the ballot as Constitutional Amendment 1.

"We hope this brings an end to it and that the people can vote in November on whether they want to adopt these changes," said attorney Chuck Hatfield, who represents Clean Missouri.

The initiative has been opposed in court by the president of the Missouri Chamber of Commerce and Industry and a Republican voter who was represented by the law firm of Missouri Republican Party Chairman Todd Graves.
