Is there a right to privacy in the disclosure of cost information?

Appellants do not challenge the disclosure of the cost information to the government, but rather complain of the subsequent availability of the information to the public. As in Paul v. Davis, their claim is not based upon any contention that the public disclosure of the cost information will "restrict (their) freedom of action in a sphere contended to be private." We conclude that no cognizable constitutional right of privacy is implicated here. ³
