The Secretary of State to President Wilson

My Dear Mr. President: I am enclosing for your consideration a memorandum which I have made on the general subject of the detention and censorship of the mails. In this memorandum I have not sought to traverse the arguments advanced by the Allied Powers in their reply to our note of May 24th, but have sought to view the subject as impartially as possible from the standpoint of principle and applied common sense. An insistence on technicalities will, I feel sure, get us nowhere as each side can bulwark itself behind many legal precedents, which on account of the facts in each case appear to be reasonable and sound. It seems to me, therefore, that we must go back to general principles and determine by logic some solution of the problem.

In considering the subject I think that we should bear in mind that, while we are neutral in the present war, we may be belligerent in the next and may deem it necessary to do certain things which we now regard as extreme restrictions upon neutrals. It would be most unfortunate to tie ourselves too tightly to a proposition which we would regret in the future.

[Page 322]

After you have read the memorandum you will perceive that I have reached the following conclusions:

That there are two classes of mails: First, mails going to or toward the Central Powers; and, second, mails coming from those powers or from contiguous neutral countries.

That, as to mails coming from neutral countries included in the second class, there is no basis at law or in reason for the inspection of either sealed or unsealed mails.

That, as to the first class there exists the right to inspect unsealed mail and to detain contraband articles; but as to the inspection of sealed mail there is a conflict of principles due to the law of contraband and the theory of inviolability, principles which are irreconcilable because the superiority of right of exercise has never been determined.

From these conclusions the only solution of the problem which suggests itself to me is this:

That we insist that mail outcoming from neutral countries in continental Europe shall be treated as inviolable and shall not be subject to detention, inspection or seizure.

That the extent and exercise of the belligerent right to detain, inspect or seize mail ingoing to continental Europe shall be submitted immediately to arbitration or to a joint commission of inquiry, which shall seek to apply the conflicting principles equitably and lay down a series of rules which may be adopted as a modus operandi by this Government and those of the Allies.

After I hear from you in this matter, and provided you approve of this plan, I might take up the matter informally with the British Ambassador and get the views of his Government.

Of course the difficulty is as to the procedure while the commissioners are considering the question. I think that all we could do is to get the best terms possible.

Faithfully yours,

Robert Lansing

Memorandum by the Secretary of State on Censorship of Mails

The problem of the seizure and detention or censorship by a belligerent of mails carried in a neutral bottom from a neutral port to an enemy destination or to a neutral destination whither they may without interruption be transmitted to the enemy, results from the conflict of two established principles:

First. The belligerent right to remove from neutral vessels on the high seas articles of contraband and contraband communications; and

[Page 323]

Second. The neutral right to have mails between neutral countries, and innocent private correspondence between a neutral country and a belligerent country treated as inviolate by belligerents.

It is manifest that neither of these rights can be exercised to their full extent and the other right maintained to any degree. The unimpaired exercise of both rights is impossible. They cannot be brought into harmony.

The question, therefore, arises as to whether the belligerent right of mail-examination or the neutral right of mail-inviolability is the superior right and should govern any attempted adjustment of the conflict between the two rights.

In the first place, all belligerent rights on the high seas are abnormal and contrary to the usual practice of nations in times of peace. As a general proposition, the belligerent right should be strictly construed against the belligerent exercising it, and liberally construed as to the neutral whose normal rights are impaired by such exercise. As a rule, therefore, when a belligerent right conflicts with a recognized neutral right, the latter should be the controlling factor in reaching an adjustment of the differences.

On the other hand, if the full exercise of the neutral right destroys or renders impossible of exercise a recognized belligerent right, it is open to question whether or not the neutral rights should not be so modified as to permit a reasonable exercise of the belligerent right.

The argument in favor of the modification of a neutral right under such conditions rests primarily on the fact that the national safety of the belligerent is at stake, which is in truth the foundation of all exceptional rights over neutrals and their property on the high seas conferred upon belligerents. If the deprivation of a belligerent right materially reduces the possibility of injury to an enemy, or if such deprivation increases the efficiency of an enemy is a neutral justified in insisting on the observance of neutral right which deprives the belligerent of the right to which he would be entitled if the neutral right did not exist?

If the neutral right is of vital interest there would seem to be strong justification for insisting upon its full observance even though the belligerent right in conflict was nullified by such observance. But, if the neutral right recognized merely the continuance of a practice usual in times of peace, the interruption of which would not impair the vital interests of a neutral state but would cause much inconvenience and possible pecuniary loss to the nationals of that state, it would be of doubtful justice to insist on the exercise of the neutral right without regard to its effect on the belligerent right.

In large measure the limitations upon neutrals which result from the exercise of belligerent rights on the high seas cause inconvenience [Page 324] and loss to neutrals in their commercial enterprises. It is a consequence which is considered unavoidable and is submitted to because of the recognition of the supreme right of a nation to defend itself by preventing aid from reaching its enemy. Like the right of visit and search, the right to seize articles of contraband and contraband communications is one of the oldest and most universally recognized rights of belligerents. It was established before postal treaties were negotiated and before the post had become a world wide institution and mails measured by tons. The long unquestioned acceptance of the law of contraband raises the query whether the expansion of postal facilities to such an extent as to offer a practical means of transporting contraband articles and correspondence can lessen the full force of the more ancient belligerent right.

To determine whether a mail bag contains contraband articles or contraband correspondence requires inspection by a belligerent. Such an inspection can be easily made of unsealed packets, and little argument can be urged against the propriety of such inspection or against the confiscation of articles of contraband which are found. The chief complaints would arise from the seizure of articles of doubtful contraband character and from undue delay in permitting innocent articles to proceed to their destination.

In the case of sealed mail the real difficulty arises. Admitting that the law of contraband can be applied to all articles and communications found on neutral vessels on the high seas, it is manifest that the law can [not?] be applied to sealed packets without their being opened and inspected. But, if the law of contraband cannot be applied to such mail, a channel of communication and transportation would be open to an enemy, through which might flow uninterruptedly contraband of all sorts because of moderate rates of postage and the size of packages now permitted in first class mail.

It cannot be expected that a belligerent will permit, if there is power to prevent, this means of intercourse to remain free to an enemy; and it is very doubtful whether a neutral is justified in objecting to inspection of sealed mail and to the censorship of correspondence provided the belligerent scrupulously confines the inspection and confiscation of mail matter to that which is unquestionably contraband. If the inspection of correspondence is for the purpose of obtaining information either of a military or civil nature it exceeds the limits of right. The sole legitimate reason for interruption of mail is to prevent contraband articles and information reaching the enemy. When it is manifest that the acquisition of knowledge is a principal ground for the seizure or detention of mail, it can find no warrant in law or in usage.

The foregoing applies to sealed mail destined to the enemy. In the case of sealed mail between neutral countries, one of which is [Page 325] contiguous to the enemy with whom are uninterrupted postal facilities, the problem is more complex. Admitting the doctrine of ultimate destination, how can the ultimate destination of sealed mail be determined unless it is opened and inspected? If it is not opened, but is permitted to pass with the seals unbroken, has not a sure and safe channel been found for the conduct of an extensive trade in contraband with the enemy of the belligerent allowing its passage? Is there not justification for the belligerent in insisting on an inspection of sealed mail going to a neutral country contiguous to enemy territory?

However strong may be the argument in favor of the justice of a belligerent’s rights to inspect sealed mail going toward an enemy and to apply the law of contraband to such mail, the argument cannot be urged with equal force in regard to sealed mail, or even unsealed mail, leaving a neutral country adjacent to enemy territory. The law of contraband, depending upon enemy destination, cannot be invoked. It may be claimed that the right of inspection and seizure arises from the fact of enemy origin of articles, but that cannot be conceded as giving legal effect to such an act, and it certainly cannot be invoked in the case of sealed correspondence.

The opening of sealed correspondence would appear to be for the purpose of obtaining information for the use of the belligerent. That is the unavoidable presumption. Such a purpose is illegal and improper and constitutes a very legitimate ground of complaint by the neutral on whose vessel the mail is carried and also by the neutral to which it is destined. Such mail at least should be absolutely inviolate.
