Resolved (two thirds of the Senate present concurring), That the Senate advise and consent to the adherence on the part of the United States to … the Permanent Court of International Justice … subject to the following reservations and understandings, which are hereby made a part and condition of this resolution, namely:

• That such adherence shall not be taken to involve any legal relation on the part of the United States to the League of Nations or the assumption of any obligations by the United States under the Treaty of Versailles….
• That the United States may at any time withdraw its adherence to the said protocol and that the statute for the Permanent Court of International Justice adjoined to the protocol shall not be amended without the consent of the United States.
• That the court shall not … without the consent of the United States, entertain any request for an advisory opinion touching any dispute or question in which the United States has or claims an interest….

Resolved further, That adherence to the said protocol and statute hereby approved shall not be so construed as to require the United States to depart from its traditional policy of not intruding upon, interfering with, or entangling itself in the political questions of policy or internal administration of any foreign state; nor shall adherence to the said protocol and statute be construed to imply a relinquishment by the United States of its traditional attitude towards purely American questions.
