PHOENIX -- Former Arizona Gov. Fife Symington is among those asking the state Supreme Court to throw out a lawsuit challenging Gov. Jan Brewer's expansion of Medicaid insurance plan for the poor.
A group of lawmakers from both parties joined Symington and business and hospital groups in a friend of the court brief Tuesday.
The Arizona Court of Appeals ruled in April that conservative Republican lawmakers have the right to sue over a hospital assessment that funds the expansion. That ruling overturned a lower court judge's decision dismissing a suit filed by Republicans in the House and Senate who sued last year.
The conservative lawmakers argued that the assessment is essentially a tax requiring a two-thirds majority vote to pass.
The high court is expected to act in August.
