When I hear “unconstitutional” and “Hawaii” I think of this:
Hawaii Housing Authority v. Midkiff, 467 U.S. 229 (1984), was a case in which the United States Supreme Court held that a state could use eminent domain to take land that was overwhelmingly concentrated in the hands of private landowners and redistribute it to the wider population of private residents.[1]
