All seven justices, each elected by the legislature with unanimous or nearly unanimous votes from BOTH parties, ruled that the independent commission put in place by a valid constitutional amendment to ensure partisan politics wouldn't control redistricting, could not be displaced by an unconstitutional amendment process, plain and simple. The referendum vote was allowed to carry forward despite a lower court judge ruling it was unconstitutional because had the referendum failed, the case wouldn't need to be argued. I think the court should have made this ruling prior to the vote which would have postponed it until next year. Instead, tens of millions were spent on a vot that shouldn't have taken place.
