Harlan delivered the opinion of the court.
In
United States
v. Lippitt,
We are of opinion that the claim here in suit — although
*232
by reason of its character "cognizable by the Court of Clаims" — cannot properly be made the basis of a judgment in that court. As the United States are not liable to be sued, except with their consent, it was competent for Congress to limit their liability, in that respect, to specified causes of action, brought within a prescribed period.
Nichols
v.
United
States,
The general rule that limitatiоn does not operate by its own force as a bar, but is a defence, and that the party making suсh a defence must plead the statute if he wishes the benefit *233 of its provisions, has no application to suits in the Court of Claims against the United States. An individual may waive such a defence, either expressly or by failing to plead the statute; but the Government has not expressly or by implication conferrеd authority upon any of its officers to waive the limitation imposed by statute upon suits against the United Stаtes in the Court of Claims. Since the Government is not liable to be sued, as of right, by any claimant, and since it hаs assented to a judgment being rendered against it only in certain classes of cases, brought within a prеscribed period after the cause of action accrued, a judgment in the Court of Claims for the amount of a claim which the record or evidence shows to be barred by the statute, would be erroneous.
The judgment is
Affirmed.
