Does it cover any situations outside of what the Council is contemplating -- people who have moved to states that will not divorce them because they do not recognize gay marriages? Well, it expressly covers only same-sex marriages, but it might allow same-sex divorce when the parties' states or countries lack divorce jurisdiction for some reason other than disapproving of same-sex marriage. The key wording is --
"An action for divorce by persons of the same gender, even if one of or neither party to the marriage is a bona fide resident of the District of Columbia at the time the action is commenced, shall be maintainable if the following apply:
“(A) The marriage was performed in the District of Columbia; and
“(B) Neither party to the marriage resides in a jurisdiction that will maintain an action for divorce; provided that it shall be a rebuttable presumption that a jurisdiction will not maintain an action for divorce if the jurisdiction does not recognize the marriage.
