Ordered that the order is affirmed insofar as appealed from; and it is further,
Ordered that the order is reversed insofar as cross-appealed from, that branch of the claimant's motion which was to amend the claim is denied, the defendant's cross motion for summary judgment is granted, and the claim is dismissed; and it is further,
Ordered that the defendant is awarded one bill of costs.
The Court of Claims correctly denied the claimant's motion for summary judgment. The reduction in the space occupied by the defendant in the claimant's building varied the terms of the approved lease and, accordingly, required an independent approval of the State Comptroller to be valid. Since approval was not obtained, the State is not liable for the rents now alleged by the claimant to be outstanding (see, State Finance Law § 112 [a]; City of New York v. State of New York, 87 N.Y.2d 982).
The claimant may not maintain a cause of action to recover for unjust enrichment by the State under the circumstances of this case (see, Rosefsky v. State of New York, 205 A.D.2d 120; cf., Parsa v. State of New York, 64 N.Y.2d 143). Therefore, the Court of Claims erred when it granted, in part, the claimant's motion to amend the claim to add that cause of action and conditionally granted the State's cross motion for summary judgment unless the claimant filed supplemental papers to support the claim. Accordingly, the claim must be dismissed.
