Once again, an Illinois statewide initiative to create an independent redistricting commission (to draw state legislative districts) is fighting to get on the ballot. See this story. Although the initiative has twice as many signatures as are required, it is being challenged on the basis that the Illinois Constitution does not permit initiatives on this subject.
Illinois has had the statewide initiative since 1979, but in all those years, only one initiative has ever appeared on the ballot. That is because the state constitution only permits initiatives that affect the legislature. The initiative that qualified eliminated cumulative voting and multi-member districts for the Illinois House. Thanks to Jan Tucker for the link.
