A federal judge on Friday placed on hold a state domestic partnership law that was set to take effect Jan. 1, pending a February hearing.
The law would give some spousal rights to same-sex couples.
Opponents asked U.S. District Judge Michael W. Mosman to intercede after the Oregon secretary of state's office ruled in October that they had failed to collect enough valid signatures on a referendum to block the law.
The Oregon measure covers benefits related to inheritance rights, child-rearing and custody, joint state tax filings, joint health, auto and homeowners insurance policies, visitation rights at hospitals and others. It does not affect federal benefits for married couples, including Social Security and joint filing of federal tax returns.
