“Whether the new law was intended to be at once applicable to the authors of all nations who were parties to the Berne Convention of 1885-86; whether the Executive of the United States has authority now to accede to this convention, and join the International Union under the provisions of Article XVIII.; whether this would require the concurrent action of the President and Senate; or, finally, whether an act of Congress would be required (as Great Britain had to pass an act through Parliament to make that country a party to the Berne International Union), all these appear to me to be open questions, owing to lack of precision in the Act of March 3, which was passed in a crowded state of the public business, and not fully digested by a committee, especially with regard to the Berne Convention.”
