Redistricting authority: 
U.S. Congressional Districts – Legislative.  House Committee on Election and Senate Committee on Ethics and Elections.  The Legislature devises a reapportionment plan and votes on it during regular session. The Governor has veto power over the legislation.  Within 15 days after the publication of the legislation, the AG petitions the Supreme Court to determine the validity of the plan.  The Supreme Court has 30 days to determine this.  If they determine that it is not valid, then the Legislature has 15 days to come up with another plan.  After that plan is voted on, the AG again petitions the Supreme Court, and they have 10 days to determine the validity. If it is again invalid, the Legislature has 15 days to pass another bill. 

State Legislative Districts – Legislative. Same as above.
