The Arizona Supreme court upholds the state's Medicaid expansion law. In a unanimous decision, the justices rejected arguments by the attorney for some Republican lawmakers that of an assessment on hospitals that helps pay for health care for 400,000 Arizonans was illegally enacted by the legislature in 2013. The attorney argued that the assessment is really a tax that required a two-thirds vote. It was approved by a simple majority. The court ruled that since the assessment was approved by a state agency it is exempt form the two-thirds rule.
