A state Circuit Court judge Wednesday declared that the gay marriage law that took effect in December is constitutional. Judge Karl Sakamoto cited the legislative intent behind a 1998 amendment, which was that the definition of marriage was a fundamental policy issue that should be decided by the Legislature. Representative Bob McDermott had challenged the law and says he'll appeal the judge's ruling.  McDermott says voters believed in 1998 that they had banned gay marriage through a state constitutional amendment that gave the Legislature the power to reserve marriage to heterosexual couples.
