The question asks about a specific legal holding concerning the recognition of authorities in international law. It focuses on whether a distinction exists between 'defacto' and 'dejure' recognition when determining the effect of international acts performed by a recognized entity.
In the case of Luther V. Sagar, the court held that for the purpose of giving effect to the international acts of a recognised authority, there is no distinction between defacto and dejure recognition.
This means that whether an authority is recognised formally (dejure) or in fact (defacto), its actions on the international stage are treated similarly regarding their legal effect, according to this ruling.
