A coalition of educators and community groups has filed a legal challenge, questioning the constitutionality of Washington's new charter schools law.

The "legal demand" filed Wednesday asks Washington's attorney general to investigate seven constitutional issues with the new law approved by voters in November.

For example, they don't like the way the new law would divert public school money to support private non-profit organizations.

The coalition is led by the state teacher's union, the League of Women Voters and El Centro de la Raza.

The group believes the new law also violates a requirement that the superintendent of public instruction supervise everything related to public schools.

The coalition says if the attorney general doesn't respond to their complaint, they will file a lawsuit in state courts.
