It appears from the initial scheduling order from the Sixth Circuit Court of Appeals, that all of the briefs will be filed prior to the end of June. This schedule may change (and hopefully be expedited), but for now that is the schedule. In the meantime, Michigan’s Governor and Attorney General are directing all State officials to delay recognition of all marriages whether performed in Michigan or in another state, pending the stay. The Federal Attorney General, however, has issued a statement that all of the marriages performed in Michigan last Saturday will be recognized for Federal purposes.
The statement can be found here.
