[Footnote 90: Therefore treaties concluded by Canada with foreign States are not Canadian treaties, but treaties concluded by Great Britain for Canada. Should Colonial States ever acquire the right to conclude treaties directly with foreign States without the consent of the mother-country, they would become internationally part-sovereign and thereby obtain a certain international position.]
[Sidenote: Divisibility of Sovereignty contested.]
§ 66. The distinction between States full Sovereign and not-full Sovereign is based upon the opinion that sovereignty is divisible, so that the powers connected with sovereignty need not necessarily be united in one hand. But many jurists deny the divisibility of sovereignty and maintain that a State is either sovereign or not. They deny that sovereignty is a characteristic of every State and of the membership of the Family of Nations. It is therefore necessary to face the conception of sovereignty more closely. And it will be seen that there exists perhaps no conception the meaning of which is more controversial than that of sovereignty. It is an indisputable fact that this conception, from the moment when it was introduced into political science until the present day, has never had a meaning which was universally agreed upon.[91]
[Footnote 91: The literature upon sovereignty is extensive. The following authors give a survey of the opinions of the different writers:--Dock, "Der Souveränitäts-begriff von Bodin bis zu Friedrich dem Grossen," 1897; Merriam, "History of the Theory of Sovereignty since Rousseau," 1900; Rehm, "Allgemeine Staatslehre," 1899, §§ 10-16. See also Maine, "Early Institutions," pp. 342-400.]
[Sidenote: Meaning of Sovereignty in the Sixteenth and Seventeenth Centuries.]
§ 67. The term Sovereignty was introduced into political science by Bodin in his celebrated work, "De la république," which appeared in 1577. Before Bodin, at the end of the Middle Ages, the word _souverain_[92] was used in France for an authority, political or other, which had no other authority above itself. Thus the highest courts were called _Cours Souverains_. Bodin, however, gave quite a new meaning to the old conception. Being under the influence and in favour of the policy of centralisation initiated by Louis XI. of France (1461-1483), the founder of French absolutism, he defined sovereignty as "the absolute and perpetual power within a State." Such power is the supreme power within a State without any restriction whatever except the Commandments of God and the Law of Nature. No constitution can limit sovereignty, which is an attribute of the king in a monarchy and of the people in a democracy. A Sovereign is above positive law. A contract only is binding upon the Sovereign, because the Law of Nature commands that a contract shall be binding.[93]
