The Crown furthermore authorises under the sign manual the expenditure of public money in accordance with the appropriations made by Parliament, and then expends the money. It can grant charters of incorporation, with powers not inconsistent with the law of the land, so far as the right to do so has not been limited by statute; but in consequence of the various reform acts, municipal corporation acts, and local government acts, no charter conferring political power can now be created except in pursuance of statute, while even commercial companies usually require privileges which can be given only by the same authority.[22:1] The Crown grants all pardons, creates all peers, and confers all titles and honours. As head of the Established Church of England it summons Convocation with a license to transact business specified in advance. It virtually appoints the archbishops, bishops and most of the deans and canons, and has in its gift many rectorships and other livings.[22:2] As head of the Army and Navy it raises and controls the armed forces of the nation, and makes regulations for their government, subject, of course, to the statutes and to the passage of the Annual Army Act. It represents the empire in all external relations, and in all dealings with foreign powers. It has power to declare war, make peace, and conclude treaties, save that, without the sanction of Parliament, a treaty cannot impose a charge upon the people, or change the law of the land, and it is doubtful how far without that sanction private rights can be sacrificed or territory ceded.[22:3] [Sidenote: Executive Powers under Statutes.]
