More excerpts from the ruling:
“There also is no violation of the state due process clause. DOMA bears a reasonable relationship to legitimate state interests — procreation and child-rearing. Nor do we find DOMA invalid as a violation of privacy interests protected by article I, section 7 of the Washington State Constitution. The people of Washington have not had in the past nor,
at this time, are they entitled to an expectation that they may choose to marry a person of the same sex.
Finally, DOMA does not violate the state constitution’s equal rights amendment because that provision prohibits laws that render benefits to or restrict or deny rights of one sex. DOMA treats both sexes the same; neither a man nor a woman may marry a person of the same sex.”
