governor and nominee for lieutenant governor run together on the same ticket. Alaska's court system has four levels: the Alaska Supreme Court, the Alaska Court of Appeals, the superior courts and the district courts. The superior and district courts are trial courts. Superior courts are courts of general jurisdiction, while district courts hear only certain types of cases, including misdemeanor criminal cases and civil cases valued up to $100,000. The Supreme Court and the Court of Appeals are appellate courts. The Court of Appeals is required to hear appeals from certain lower-court decisions, including those regarding criminal prosecutions, juvenile delinquency, and habeas corpus. The Supreme Court hears civil appeals and may in its discretion hear criminal appeals.

He officially rejoined the Republican party in 1994.

The new law means people over 21 can consume small amounts of cannabis. The first legal marijuana store opened in Valdez in October 2016. Voter registration Taxes To finance state government operations, Alaska depends primarily on petroleum revenues and federal subsidies. This allows it to have the lowest individual tax burden in the United States. It is one of five states with no sales tax, one of seven states with no individual income tax, and—along with
