Continually Reassuring Payment Until the Cause of Action Has Already Expired
In Department of Public Welfare v. UEC, Inc., 483 Pa. 503, 397 A.2d 779 (1979), the Commonwealth entered into a contract with a contractor, had the contractor perform under the contract and admitted its obligation to pay for the work performed.
Nevertheless, while continually reassuring the contractor that payment would be made, the Commonwealth did not pay, and the time for the contractor to pursue a cause of action expired.
The supreme court held that the Commonwealth could not avoid an admitted contract obligation by saying "too bad, you shouldn't have believed us when we told you we'd pay you." Id. at 514, 397 A.2d at 784.
