John Culhane emphasizes the importance of a Pennsylvania lawsuit:
Palladino v. Corbett is the first case to attack a state law that declares a same-sex marriage from another state “void.” That challenge is quite likely to succeed. If it does, it will effectively tear down the whole edifice of refusing to recognize same-sex marriage, and serve as a model for attacks across the country. …
If Palladino and Barker win, and Pennsylvania has to recognize their marriage, the state still won’t have to authorize its own same-sex weddings. But that will soon become a distinction without a difference. Pennsylvania couples can plan their destination weddings in all of New England, New York, Delaware, Maryland, and D.C.—and head home knowing that their marriages are also legal and binding in the state of Pennsylvania. And once this strategy catches on around the country, we’ll have gay couples living with the same rights and protections as straight couples everywhere—even if some states continue to pretend otherwise.
