A Marion Superior Court judicial panel has struck down a redistricting ordinance drawn up by City-County Council Republicans in late 2011 and signed into law by Indianapolis Mayor Greg Ballard just as Democrats took majority control of the council.The panel of five judges, voting along partisan lines, ruled 3-2 that the redistricting plan signed by Ballard, a Republican, was not properly drawn up under Indiana law because it was done before 2012. Indiana law, in a statute applying specifically to Marion County, says the council must redraw the 25 districts’ boundaries during the second year after the census, which last was conducted in 2010.
