Text: The Postal Service commented that, in its view, legal constraints would not preclude a contract mechanism in principle, but that no such arrangement would be permissible without the Commission's participation in accordance with 39 U.S.C.
Entailment: They said it was a completely legal thing to use in a contract but that it did require approval by the Commission.
Contradiction: The contract mechanism was, as stated by the Postal Service, illegal.
