Mark J. Bennett & Nicole Roughan have posted “Rebus Sic Stantibus and the Treaty of Waitangi” on SSRN. This is a very interesting paper, a response to the argument put forth by renowned legal thinker Jeremy Waldron that the doctrine of rebus sic stantibus could be applied to the Treaty of Waitangi to effectively abrogate it. In short, this argument goes, the passage of time and radically changed political realities could serve to render the Treaty unenforceable.
This, I think, is a similar argument to what the Vermont Supreme Court made in State v. Elliott and what the U.S. Supreme Court did in Sherrill v. Oneida Indian Nation — where the passage of time and changed political circumstances appear to render Indian treaty rights nugatory. In short, it’s troubling.
