The purpose of this article is to inquire what is requisite to bind the state to an international engagement. We might ask what is the international effect of constitutional limitations on the power to make treaties, thus coming directly to the most controverted aspect of the problem. But there are also less formal agreements, as well as unilateral acts, all falling within one great category of negotia juris whose common characteristic is that they express the will of a state or states. In the following discussion we shall say simply “act,” meaning thereby an official act whose purpose is to create, alter, or extinguish rights in international law.

67 E.g., by Art. 9 of the Swiss Constitution, cantons are competent to treat with foreign states on matters of police and local traffic.
68 E.g., Art. II, sec. 2 of the U. S. Constitution: the President “shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two thirds of the Senators present concur.”
69 Perhaps Art. 26 of the Norwegian Constitution, as amended in 1931, would fall under this head. By its terms all treaties concerning matters of special importance . . . are not binding until approved by the Storting. Arnold, Treaty-Making Procedure, p. 54. Unless an authentic interpretation had been rendered, or practice had given some specific meaning to “matters of special importance,” other high contracting parties could not know the scope of this expression.
70 E.g., the common provision that it is for parliament to make appropriations (even when necessary to give effect to a treaty).

Translation from Dodd, Modern Constitutions, I, 330: “It shall be the duty of the Emperor to represent the Empire among nations, . . . to enter into alliances and other treaties with foreign countries. ... So far as treaties with foreign countries relate to matters which, according to Art. 4, are to be regulated by imperial legislation, the consent of the Bundesrat shall be required for their conclusion, and the approval of the Reichstag shall be necessary to render them valid.”

76 Jellinek, op. cit., p. 341ff: where, as in Belgium, the constitution provides that a treaty shall have no effect until parliament approves, such approval is an implied suspensive condition. Where, as in Great Britain, legislation may be necessary to carry a treaty into effect, its enactment is a resolutive condition. Seligmann, op. cit, p. 146ff, argued that a treaty is existent if concluded by the respective chiefs of state, but is not effective—i.e., there is no obligation to carry out its provisions—until the constitutional requirements have been complied with.

96 The case of an heir dealing with a legatee aliena juris. Ad Sabinum, in Lenel, Palingensia iures civiles, Vol. 2, p. 1019ff. There were other exceptions. E.g., under the S. C. Vel-leianum a creditor could not enforce an undertaking by a woman to answer for the debts of another. But it was not applicable if the woman had used fraud (Dig. 16.1.2.3) or if there was excusable error on the part of the creditor (Dig. 16.1.4), and in some other cases. The S. C. Macedonianum forbade loans to a filiusfamilias: but where the lender fell into error because the filius was generally believed to be sui juris, the debtor could not invoke the benefit of the S. C. (Dig. 14. 6. 3).

Ihering had been considering the case where A leads B to contract with him; the contract later proves to be a nullity, for some reason such that some degree of culpa may be charged to A. His conclusion was that each party owed a duty to the other to exercise diligence in respect to the formation as well as the execution of a contract, and that B would be entitled to receive his negative Vertragsinleresse—i.e., to be indemnified for his actual loss.
