SEATTLE (AP) -- Arguments are schooled to be heard in King County Superior Court on a lawsuit challenging the constitutionality of Initiative 1053, which requires a supermajority of the Legislature to raise taxes or fees or close tax loopholes.
The lawsuit is brought by the League of Education Voters, the state's largest teacher's union, parents, taxpayers and lawmakers.
Initiative 1053 was approved by Washington voters in November 2010 and has prevented lawmakers from adopting several tax and fee increases since then.
Lawmakers are allowed to change or suspend initiatives after two years. But initiative sponsor Tim Eyman has said he plans to introduce a similar initiative every two years to try to keep that from happening.
On Friday, Superior Court Judge Bruce E. Heller will hear arguments for summary judgment.
