PORTLAND, Ore.—A Multnomah County Circuit Judge July 17 decided that two Oregon laws on parental rights violate the state’s constitution when applied to same-gender couples but said an upcoming legislative change will remedy it.

Judge Eric Bloch’s decision comes after a same-sex couple filed a lawsuit against the state last year. The couple, Jean Frazzini and K.D. Parman, had a child two years ago through artificial insemination. The child’s birth certificate recognizes only Parman—the birth mother—as the child’s parent. The birth certificate arrived at their home with Frazzini’s name crossed out.

They filed suit, saying it violated an earlier decision that found providing benefits to couples but not allowing the same benefits to same-sex couples constitutes illegal discrimination.

Judge Bloch found in their favor and determined Oregon’s new domestic partnership law would be a solution to the problem if it is goes into effect as planned on Jan. 1.

However, the couple and the gay rights support group backing them say a signature-collection effort is already under way to delay and ultimately overturn the law.
