The Washington State Supreme Court will consider a top lawmaker’s legal challenge of voter-approved tax increase limits. The lawsuit is from Spokane Democrat and Senate Majority Leader Lisa Brown, who is challenging a pair of initiatives that say tax increases need to get supermajority approval from the Legislature. State attorneys defending the laws wanted to have the lawsuit dismissed. But in documents released Monday, the High Court’s commissioner determined the case can continue. Brown launched her lawsuit during this year’s Legislative session, after the Senate failed to garner the required two-thirds vote for a proposed tax increase on liquor. Brown claims the higher vote requirement is illegal, because it alters the state constitution’s voting thresholds without actually amending the constitution. (AP)
