It was decided by the Court of Appeal (Bankes and Atkin I.JJ., Scrutton L.J. dissenting on another ground), in Commercial and Estates Co. of Egypt v. Board of Trade, that the Crown has by prerogative the right to requisition the goods of neutrals found in this country, on payment of compensation, where such seizure is necessary for the defence of the realm. This right corresponds to what is known in International Law as “ the right of angary.” It is proposed to examine in this paper the nature and extent of this prerogative right.
