Ordered that the order is affirmed, with costs.
In moving to vacate the order granting the defendant's motion to dismiss his claim, the claimant was required to establish both a reasonable excuse for his default and a meritorious claim ( see CPLR 5015 [a] [1]; Blumberg v State of New York, 208 AD2d 581). The claimant failed to demonstrate that he has a potentially meritorious claim. Accordingly, the Court of Claims providently exercised its discretion in denying the claimant's motion.
