On Wednesday, Columbia received final approval for its general project plan from the New York State Public Authorities Control Board.
On Thursday, however, oral arguments were heard in a case challenging Columbia's use of eminent domain for the project. Two of the judges seemed skeptical about whether the taking would be a valid one, bringing up issues relating to the propriety of the blight study, the constitutionality of New York's eminent domain laws, and whether a private university should be considered a public purpose. A decision is expected this summer, but appeals could hold up the project for some time.
