Summary judgment is not a privilege, and it was not expected despite media hype. The situation that precipitated in one in New Jersey was due to the unique circumstances there. The criteria for summary judgment at a minimum requires no disputes over facts. Since New Jersey already had a mandatory precedent, and the fact that DOMA was overturned, judgment was granted as a matter of law to Garden State Equality and the plaintiffs.Sadly, Michigan didn't do shit today and the judge postponed the decision for February.
The Constitution only guarantees due process, which we will get at trial.
Even if we had summary judgment, I guarantee you that the Republican 6th Circuit would have slapped it down. They would have remanded it for trial, which would have just delayed the case by months.
That being said, there is little to worry about. The judge in this case actually asked the plaintiffs to sue for marriage. The case was originally only over adoption.
