Take the following as truth: 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.
Then the following statement: "The provision was favorable to the Postal Service and legal, but it would be up to the Commission to decide whether it could be implemented." is true, false, or inconclusive?
