A hearing is scheduled for July 17.  The MN Supreme Court doesn’t publish appellate briefs, but most of the litigants have published copies themselves.  Here are the petitioners’ opening petition and brief, the legislature’s  opposition, and the petitioners’ reply.  And here are amicus briefs from the City of St. Paul, Minnesota Majority, and Sen. Newman and Rep. Kiffmeyer; I’m still looking for some others.
