Wash. Rev. Code § 77.110.040
The people of the state of Washington declare that under the Indians Citizens Act of 1924, all Indians became citizens of the United States and subject to the Constitution and laws of the United States and state in which they reside. The people further declare that any special off-reservation legal rights or privileges of Indians established through treaties that are denied to other citizens were terminated by that 1924 enactment, and any denial of rights to any citizen based upon race, sex, origin, cultural heritage, or by and through any treaty based upon the same is unconstitutional.
No rights, privileges, or immunities shall be denied to any citizen upon the basis of race, sex, origin, cultural heritage, or by and through any treaty based upon the same.
