The People, universally, are sovereign, the highest civil authority in the nation, because their inalienable and inherent God-given natural rights are the supreme natural law that is the LAW of the laws, seating sovereignty (simultaneously supreme, plenary/ALL political authority of every kind in full degree) in the People. All political/civil governing authority belongs to, resides in, and comes from the People; and all authority possessed by civil/institutional government is the People's authority, provisionally entrusted by the People to government for the protection, facilitation, and realization of the People's human rights and good and the common good of society.
The People's natural rights being the natural/ontological (in being/reality) seat and source of all political authority, and the People's natural rights being inalienable, the sovereignty of the People is inalienable; no government, no human power, no constitution or law of man can take away the People's sovereignty or legitimately obstruct or deny or prevent the People from exercising their sovereignty or the full range of their political rights as sovereign. The sovereignty of the People is natural, universal, inalienable, immutable, and indivisible.
"God gave political authority first to the people. Afterward, as observed by St. Thomas Aquinas, Cajetan, St. Robert Bellarmine, and Francisco Suarez, S.J., government only possesses authority by some manner of transfer by or transmission from the People." (Yves R. Simon, A General Theory of Authority)
The authority of government, no matter what the form of government, is received, dependent, contingent (hinged on the People), alienable, mutable, and divisible.
Thus, while the People's sovereignty is permanent, inalienable, unalterable, and irremovable, all authority possessed by government is the People's authority, not government's, and has only been entrusted to government on condition that it be used for its proper, just purpose, and is subject to being revoked, withdrawn, and removed by the People, especially when government is corrupt and treasonous (completely betrays its purpose to protect, facilitate, and realize the just requirements of the People's natural rights and the People's human good).
The sovereignty of the People, philosophically established, destroys and permanently removes all claims by the State to be sovereign. The People of the nation claiming, relying on, and resorting to the principle and doctrine of the sovereignty of the People is the philosophical solution to confronting and overcoming government's, especially corrupt, rogue, treasonous "government's", false claim to be sovereign and that the People are absolutely and always (under all circumstances) inferior in authority and power to the government, that the citizens are absolute subjects who must conform and unconditionally submit to the arbitrary, unjust demands of an unjust State.
"The People are maiestas realis (Latin, the 'real sovereign'), who hold full iura maiestatis ('rights of sovereignty'), are the true dominus reipublicae ('Lord/Master of the Republic'), and hold true dominium ('rule, dominion, ownership'), while government is only tutor and curator ('watcher, protector, and guardian') – curator reipublicae and tutor regni ('guardian of the political order' and 'watchman of the political realm')." (17th century German jurist and political philosopher Johannes Althusius, Politica, quoted by Daniel Lee, Popular Sovereignty in Early Modern Constitutional Thought)
"The People make government their absolute commissioners and deputies [absolute servants who receive their commission/assigned mission and authority from the People and are empowered by the People to act with the People's authority as the People's vicars or substitutes in guarding and protecting the People's rights and good]." (English Leveller Richard Overton, An Arrow against All Tyrants, in The English Levellers, Cambridge Texts in the History of Political Thought, quote in summary form (bracketed emphasis added))
"The 'sovereignty' of the State [institutional government] is a fiction of words believed by many and accompanied by a great deal of coercive power." (Serena Ferente, "Popolo and Law: Late Medieval Sovereignty in Marsilius and the Jurists," Chapter 4 in Popular Sovereignty in Historical Perspective, Richard Bourke and Quentin Skinner, editors (Cambridge University Press, 2016), p. 96 (quotations emphasis and bracketed emphasis added))
"The federal and state governments are in fact but different agents and trustees of the people . . . The adversaries of the Constitution seem to have lost sight of the people altogether in their reasonings on this subject . . . These gentlemen must here be reminded of their error. They must be told that the ultimate authority . . . resides in the people alone." (American founder James Madison, Federalist No. 46)
"[G]overnments which have a view to [that are oriented toward] the common interest [the natural rights and good of the People] are constituted in accordance with strict principles of justice, and are therefore true forms [authentic civil government with genuine authority]; but those which regard only the interest of the rulers are all defective and perverted forms for they are despotic...." (Aristotle, Politics (bracketed emphasis added))
"Government becomes unjust when it spurns the common good of the multitude and seeks the private good of the governing element. The more it recedes from the common good, the more it is an unjust government." (St. Thomas Aquinas, Summa Theologiae)
"For this is tyranny: being conducive to the private good of the ruler, and to the injury of the multitude." (St. Thomas Aquinas, Summa Theologiae, II-II, Question 42, "Sedition", Article 2, Reply to Objection 3 (bracketed emphasis added))
"Political obligation [duty as a matter of justice to recognize, respect, honor, and submit to legitimate rights, especially the People’s natural rights, within the citizen-government government-citizen relation] pertains not only to . . . subject and citizen but also with at least equal stringency to rulers and governors [obedience and submission, to the higher natural law, is no less for government, than it is for citizens]. By the Lockean account (as embedded in long tradition [of natural law extending back to the Greeks and the Old Testament]) the rulers are obliged to exercise their powers only for the preservation of the liberties and properties of the people. The [American] Declaration of Independence finds [King] George III to be a tyrant precisely because he has perverted his powers as monarch by overstepping limits imposed by both constitution and higher law [the divine and natural laws, that are the LAW of Justice] to serve his own self-interest rather than to tend the common good of the Englishmen in America." (Ellis Sandoz, A Government of Laws: Political Theory, Religion, and the American Founding, pp. 39-40 (bracketed emphasis added))
"A regime that oversteps limited powers or imposes rule that fails to be just and reasonable by the standard of the higher law [the eternal and natural laws (called by Edward J. Cahill, S.J. (The Framework of a Christian State), the "twin-part divine law"] is in rebellion against the people and God [and, consequently, the People and the officials in government who are just and virtuous, are no longer obligated to obey it, but, instead, are obliged and obligated, by the higher natural and eternal laws, to follow and obey the natural law of the People's natural rights and human good, and therefore to disobey and resist illegitimate tyrannical 'government' and to right the so-called 'ship of state']." (Sandoz, Id., pp. 40-41, quote in partial summary paraphrase form (bracketed emphasis added))
