There seems to be a lot of confusion around the remedy the Mass SJC ordered. The court wrote
We face a problem similar to one that recently confronted the Court of Appeal for Ontario, the highest court of that Canadian province, when it considered the constitutionality of the same-sex marriage ban under Canada's Federal Constitution, the Charter of Rights and Freedoms (Charter). See Halpern v. Toronto (City), 172 O.A.C. 276 (2003). Canada, like the United States, adopted the common law of England that civil marriage is "the voluntary union for life of one man and one woman, to the exclusion of all others." Id. at, quoting Hyde v. Hyde, [1861-1873] All E.R. 175 (1866). In holding that the limitation of civil marriage to opposite- sex couples violated the Charter, the Court of Appeal refined the common-law meaning of marriage. We concur with this remedy, which is entirely consonant with established principles of jurisprudence empowering a court to refine a common-law principle in light of evolving constitutional standards. See Powers v. Wilkinson, 399 Mass. 650, 661-662 (1987) (reforming the common-law rule of construction of "issue"); Lewis v. Lewis, 370 Mass. 619, 629 (1976) (abolishing common-law rule of certain interspousal immunity).
We construe civil marriage to mean the voluntary union of two persons as spouses, to the exclusion of all others. This reformulation redresses the plaintiffs' constitutional injury and furthers the aim of marriage to promote stable, exclusive relationships. It advances the two legitimate State interests the department has identified: providing a stable setting for child rearing and conserving State resources. It leaves intact the Legislature's broad discretion to regulate marriage. See Commonwealth v. Stowell, 389 Mass. 171, 175 (1983).
In their complaint the plaintiffs request only a declaration that their exclusion and the exclusion of other qualified same-sex couples from access to civil marriage violates Massachusetts law. We declare that barring an individual from the protections, benefits, and obligations of civil marriage solely because that person would marry a person of the same sex violates the Massachusetts Constitution. We vacate the summary judgment for the department. We remand this case to the Superior Court for entry of judgment consistent with this opinion. Entry of judgment shall be stayed for 180 days to permit the Legislature to take such action as it may deem appropriate in light of this opinion. See, e.g., Michaud v. Sheriff of Essex County, 390 Mass. 523, 535-536 (1983).
Some people have thought this allowed the Mass legislature to adopt civil unions or gave it time to amend the constitution. It certainly does not do the latter as amending the constitution in Massachusetts takes several years. It is less clear from the opinion whether civil unions would suffice. The court states clearly that the state has had ample opportunity to justify the exclusion of same-sex couples from civil marriage and has not done so. It's not giving the state another six months to come up with new laws and new reasons to exclude. So why did the court give the legislature six months? I think the reason is that the court understands that the legislature may wish to make changes to other laws in light of the fact that same-sex couples will be getting married. For example,
John Derbyshire asks whether cell mates could now get married. The legislature or the department of corrections may wish to deal with such an issue. The legislature doesn't have to do anything, though. If after six months, it does nothing the department of health will be required to give marriage licenses to same-sex couples who request it.
