California legislators decided last year to ask voters whether they supported overturning a landmark ruling that allowed unlimited corporate spending to support or denounce federal candidates.

A conservative taxpayers group balked, arguing that state legislators lack the power to put advisory measures on the ballot. The California Supreme Court agreed to remove Proposition 49 and to decide in a later ruling whether it could go forward in a future election.

The court will hear arguments on the case Tuesday, generally the last step before issuing a decision. If the Legislature wins, Californians will be able to cast an advisory vote next year on whether Citizens United, a 2010 U.S. Supreme Court decision that overturned campaign spending laws, should be repealed by a federal constitutional amendment….

UC Irvine Professor Richard L. Hasen, an expert in election law, said there was “great value” in allowing voters to express disapproval of a controversial U.S. Supreme Court decision.

“On the other hand I worry about gaming the system and cluttering the ballot,” Hasen said. “It is a hard question.”
