The functions of the Emperor as such are not numerous, but, so far as they go, they are of fundamental importance. In the first place, the Emperor is commander-in-chief of the army and navy. He may control the organization of the Landwehr, or national defense; determine the strength and composition of the armed contingents; supervise the equipment and drilling of the troops; and mobilize the whole, or any part, of the forces.[301] A second group of Imperial functions are those relating to foreign affairs. "It shall be the duty of the Emperor," says the constitution, "to represent the Empire among nations, to declare war and to conclude peace in the name of the Empire, to enter into alliances and other treaties with foreign countries, to accredit ambassadors and to receive them."[302] The (p. 212) Emperor's power, however, is not in all of these directions absolute. One important limitation arises from the requirement that, under all circumstances save in the event of an attack upon the federal territory or its coasts, war may be declared only with the consent of the Bundesrath. Another is that in so far as treaties with foreign countries relate to matters which are to be regulated by Imperial legislation, "the consent of the Bundesrath shall be required for their conclusion, and the approval of the Reichstag shall be necessary to render them valid."[303] [Footnote 301: Howard, The German Empire, Chap. 12; Laband, Deutsches Reichsstaatsrecht, 345-359.] [Footnote 302: Art. II. Dodd, Modern Constitutions, I., 330.] [Footnote 303: Art. II, clause 3. Dodd, I., 331.] *222. Powers: Legislation and Justice.*--A third group of functions has to do with legislation. By the constitution the Emperor is vested with the right to convene the Bundesrath and the Reichstag, and to open, adjourn, and close them.[304] In accordance with resolutions of the Bundesrath, bills are laid before the Reichstag in the name of the Emperor; and it is the Emperor's duty to prepare and publish the laws of the Empire, as well as to supervise their execution.[305] In so far as is permitted by the constitution, and by laws from time to time enacted, decrees and ordinances may be promulgated by the Emperor, under the countersignature of the Chancellor. Speaking strictly, the Emperor possesses no veto upon measures passed in the Bundesrath and Reichstag, though in practice he may refuse to publish a law in the enactment of which he believes the ordinary formal requirements not to have been complied with. He may not withhold a measure by reason simply of its content. [Footnote 304: Art. 12. Ibid.]
