Is it possible to sue an RE?

Let’s say that an RE lets a contract for a large construction project and that the client is a very stuborn government body with its own procurement rules stipulating extreme requirements of evidence for work done before allowing the RE to certify payment. Let’s say that the client refuses to acknowledge the conditions of contract because their own procurement rules are legally and procedurally binding for themselves.

Is it then possible to sue the RE for letting a contract with terms and conditions that are not able to be performed by the client and, therefore, causing additional adminsistration, non payment for vaiations and delays in payment to the Contractor.
