delivered the opinion of the Court.
These are two petitions for writs of mandamus to the respective corporations respondent, manufacturers and sellers of tobacco, brought by the Federal Trade Commission under the Act of September 26, 1914, c. 311, § 9, 38 Stat. 717, 722, and in alleged pursuance of a resolution of the Senate passed on August 9, 1921. The purpose of the petitions is to require production of records, contracts, memoranda and correspondence for inspection and making copies. They were denied by the District Court.
The petitions allege that complaints have been filed with the Commission charging the respondents severally with unfair competition by regulating the prices at which their commodities should be resold, set forth the Senate resolution, and the resolutions of the Commission to conduct an investigation under the authority of §§ 5 and 6 (a), and in pursuance of the Senate resolution, and for the further purpose of gathering and compiling information concerning the business, conduct and practices, &c., of *305 each of the respondent companies. There are the necessary formal allegations and a prayer that unless the accounts, books, records, documents, memoranda, contracts, papers and correspondence of the respondents are immediately submitted for inspection and examination and for the purpose of making copies thereof, a mandamus issue requiring, in the case of the American Tobacco Company, the exhibition during business hours when the Commission’s agent requests it, of all letters and telegrams received by the Company from, or sent by it to all of its jobber customers, between January 1, 1921, to December 31, 1921, inclusive. In the case of the P. Lorillard Company the same requirement is made and also all letters, telegrams or reports from or to its salesmen, or from or to all tobacco jobbers’ or wholesale grocers’ associations, all contracts or arrangements with such associations, and correspondence and agreements with a list of corporations named.
The Senate resolution may be laid on one side as it is not based on any alleged violation of the Anti-trust Acts, within the requirement of § 6(d) of the act.
United States
v.
Louisville & Nashville R. R. Co.,
The mere facts of carrying on a commerce not confined within state lines and of being organized as a corporation do not make men’s affairs public, as those of a railroad company now may be.
Smith
v.
Interstate Commerce Commission,
The right of access given by the statute is to documentary evidence — not to all documents, but to such documents as are evidence. The analogies of the law do not allow the party wanting evidence to call for all documents in order to see if they do not contain it. Some ground must be shown for supposing that the documents called for do contain it. Formerly in equity the ground must be found in admissions in the answer. Wigram, Discovery, 2d ed., § 293. We assume that the rule to be applied here is more liberal but still a ground must be laid and the ground and the demand must be reasonable.
Essgee Co.
v.
United States,
The demand was not only general but extended to the records and correspondence concerning business done wholly within the State. This is made a distinct ground of objection. We assume for present purposes that even some part of the presumably large mass of papers relating only to intrastate business may be so connected with charges of unfair competition in interstate matters as to be relevant,
Stafford
v.
Wallace,
We have considered this case on the general claim of authority put forward by the Commission. The argument for the Government attaches some force to the investigations and proceedings upon which the Commission had entered. The investigations and complaints seem to have been only on hearsay or suspicion — but, even if they were induced by substantial evidence under oath, the rudimentary principles of justice that we have laid down would apply. We cannot attribute to Congress an intent to defy the Fourth Amendment or even to> come so near to doing so as to raise a serious question of constitutional law.
United States
v.
Delaware & Hudson Co.,
Judgments affirmed.
