The Missouri Supreme Court will hear an appeal of the Kansas City Council's decision not to put a plan for light rail in the city on the election ballot.

The Supreme Court said in an order Tuesday that it would hear arguments in activist Clay Chastain's long-running battle to put a light rail proposal before voters.

In 2011, petitioners submitted enough valid signatures to put Chastain's proposal for a sales tax and light rail up for a vote. But the City Council refused, saying the ballot measure violated the state constitution because it didn't fully fund construction.

A circuit court and an appeals court upheld the city's position.
