Harlan F. Stone,
Factor v. Laubenheimer — Opinion of the Court
“ Qualifying clauses are often used in treaties, statutes, and agreements where the meaning would be the same if they were omitted. Article 2 of the Convention of 1889 furnishes an example. It declares that no fugitive shall be surrendered for any offense of a political character. As no crime of that sort it listed, the provision is unnecessary. That clause, like the expression requiring criminality in both countries, is used, not to add or change meaning, but to emphasize and insure adherence to a well known general principle always held applicable in the absence of any such specification. ”
