This ruling does not only apply to NY and MI, it provides president to negate all such shipping laws. From what I have been told by an attorney who is involved with the case (winning side), all aspects of discrimination against out-of-state wineries, and possibly retailers, are null-and-void. That means that the portion of the new Texas law allowing direct shipping, that puts limits on the amount wine that can be imported in to the state is not legally binding. If Virginia only allows one case per month to be delivered from either an in-state or out-of-state winery than that will stand.
As for Maryland, it was Glendening's anti-alcohol zeal that moved the legislature to make it a felony to ship into the state. He is no where to be found, so there could be a possibility that the law can be changed.
