What this meant in practice was that military assistance could be rendered by one signatory to the other only after an allegation of unprovoked aggression had been submitted to the League and only after prior approval of the other signatories of the Locarno pact (the United Kingdom, Italy and Belgium) had been attained.
Dette betød i praksis, at den ene af parterne kun kunne yde militær støtte til den anden efter at en påstand om uprovokeret aggression var blevet indleveret til Folkeforbundet og kun efter at de andre underskrivere af Locarno-traktaten (Storbritannien, Italien og Belgien) havde godkendt det.
