sovereign

Black’s Law Dictionary 2nd Edition, pages 1098-1099:

SOVEREIGN. A chief ruler with supreme power; a king or other ruler with limited power.

In English law. A gold coin of Great Britain, of the value of a pound sterling.

-Sovereign people. A term familiarly used to describe the political body, consisting of the entire number of citizens and qualified electors, who, in their collegiate capacity, possess the powers of sovereignty and exercise them through their chosen representatives. See Scott v. Sanford, 19 How. 404, 15 L. Ed. 691.

-Sovereign power. That power in a state to which none other is superior or equal, and which are necessary to accomplish the legitimate ends and purposes of government. See Boggs. v. Merced Min. Co., 14 Cal. 309: Donnelly v. Decker,58 Wis. 461, 17 N. W. 389, 46 Am. Rep. 637; Com. v. Alger, 7 Cush. (Mass.) 81.

-Sovereign right. a right which the state alone, or some of its government agencies, can possess, and which it possesses in the character of a sovereign, for the common benefit, and to enable it to carry out its proper function; distinguished from such “proprietary” rights as  state, like any private person, may have in property or demands which it owns. See st. Paul v. Chicago, etc., R. Co., 45 Minn. 387, 48 N. W. 17.

– Sovereign states. States whose subjects or citizens are in the habit of obedience to them, and which are not themselves subject to any other (or paramount) state in any respect. The state is said to be semi-sovereign only, and not sovereign, when in any respect or respects it is liable to be controlled (like certain of the states in India) by a paramount government, (e.g., by the British empire.)Brown. “In the intercourse of nations, certain states have a position of entire independence of others, and can perform all those acts which is possible for any state for perform in this particular sphere. These same states have also entire power of self-government; that is, of independence upon all other states as far as their own territory and citizens not living abroad are concerned.  No foreign power or law can have control except by convention. This power of independence action in external and internal relations constitutes complete sovereignty.” Wools. Pol. Science, I. 204.
