[JURIST] Oregon Circuit Judge Joseph Guimond Friday upheld [ruling, PDF] the constitutionality of Measure 36 [text], an Oregon constitutional amendment banning same-sex marriage [JURIST news archive]. Judge Guimond rejected arguments that the Measure, defining marriage as "between one man and one woman", violated the state constitution [text] because it made several constitutional changes at once, and unlawfully prevented local governments from recognizing same-sex marriages performed elsewhere. The Oregon Defense of Marriage Coalition [advocacy website], which spearheaded the amendment's passage, applauded the ruling and contends that Measure 36 simply contains a one-sentence clarification of existing law. Basic Rights Oregon [advocacy website; press release response] said it will appeal. AP has more.
