From a Department of Interior press release, Secretary Ken Salazar is clear on the administration's displeasure with the Supreme Court's ruling on Carcieri vs. Salazar:

 Secretary Salazar is very disappointed by the Court's ruling," said Interior spokesman Matt Lee-Ashley. "Our attorneys are in the process of evaluating the decision. The Department is committed to supporting the ability of all federally recognized tribes to have lands acquired in trust.

 Of course, Salazar is listed as the losing party, but that's just because the Obama administration inherited the case from the Bush administration.  The statement appears to indicate a substantive opposition to the decision and resolve to work around it, most likely through Congressional action.

The decision could have big implications in Massachusetts, where the Wampanoags are hoping to develop a casino in Middleboro, near Cape Cod.  The tribe claims pre-1934 recognition (the crux of the case), though that may not be easy to prove and lead to a lengthy court battle.  Meanwhile, there's substantial political momentum to fix the law in favor of granting land-in-trust for casinos to tribes recognized after 1934.  However, that may take a while-- the committee proceedings are just beginning.

According to a recent article from the Cape Cod Times, the politics have shifted in Washington substantially enough in favor of Indian gaming and policies more favorable to tribes like the Mashpee Wampanoags:

But Steven Light, co-director of the Institute for the Study of Tribal Gaming Law and Policy at the University of North Dakota, said some of the vocal critics of Indian gaming regulations, such as McCain, are no longer in the powerful positions they once held. In January 2008, the Department of the Interior denied casino land trust applications from 12 tribes, including a Wisconsin-based tribe backed by Kerzner and Wolman that sought to develop an off-reservation casino in the Catskills of New York. It was a strong message from the Bush administration about off-reservation gaming. But there is a new administration in Washington, D.C., which made efforts to reach out to American Indians on the campaign trail and in appointing a tribe member to a key White House position in the Office of Intergovernmental Affairs, Jodi Archambault Gillette. "What isn't a test for President Obama these days?" Light said. "All the indicators are that he is supportive of tribal interests, but that doesn't mean in any way that given the political climate, you'd see the President Obama administration say off-reservation gaming is great."

Expect to hear more about the "Carcieri fix" from those who support Indian gaming and more about "reservation shopping" from those who don't in the future.  The CC Times article also brings up the possibility that a legislative "Carcieri fix" could open up a broader review of the statutes with regard to Indian gaming.  This could be welcome -- depending on the outcome -- given some of the sticky situations that have come up recently, such as with Carcieri and the Florida Seminoles.
