JEFFERSON CITY, Mo. (AP) — A Missouri judge is hearing arguments about whether to stop a policy by Gov. Jay Nixon's administration allowing legally married same-sex couples to file joint state tax returns.

Cole County Circuit Judge Jon Beetem scheduled a hearing Thursday on the request for a temporary restraining order. Several Missouri residents have filed a lawsuit challenging an executive order by Nixon to accept joint returns from same-sex couples who were legally married in another state.

The lawsuit contends Nixon's order violates a Missouri constitutional provision that recognizes marriage as only between a man and a woman. Nixon has said Missouri's tax code is tied to the federal code, and that federal officials now accept joint tax returns from married same-sex couples.
