Definition
A maxim of English constitutional law stating that the monarch bears no personal legal responsibility for acts done in the exercise of royal authority. In its original and strict sense, the king could not be sued, prosecuted, or compelled by any court, because no court had jurisdiction over the sovereign who was the source of all judicial authority.
The maxim operates on two distinct levels that researchers must keep separate:
1. Personal immunity of the monarch. The Crown as a natural person cannot be impleaded in the Crown's own courts. This was not a statement of moral perfection but a structural feature of English feudal and constitutional order: legal process ran in the king's name, so the king could not simultaneously be plaintiff and defendant.
2. Constitutional responsibility. Over time, the maxim evolved into a principle of ministerial accountability: the king can do no wrong because any wrongful act must have been done on the advice of a responsible minister, who alone bears legal and parliamentary liability. The monarch acts only through ministers; the ministers answer for the act.
By the twentieth century, the maxim had been substantially displaced in practical operation by statute. In England, the Crown Proceedings Act 1947 made the Crown suable in tort and contract in most respects, eliminating much of the practical immunity the maxim had protected.

Common Confusion
The maxim is frequently misread as a claim of royal infallibility or absolute power — a popular misreading that distorts its legal function. It was never a statement that the king's acts were morally or politically above reproach. Blackstone, writing in the Commentaries, was careful to distinguish the maxim's legal operation (no suit lies against the Crown) from its constitutional implication (ministers must answer for bad counsel). Researchers working in primary sources should also distinguish this maxim from the related but separate doctrine of act of state, which immunizes certain Crown acts in foreign affairs from domestic judicial review, and from parliamentary sovereignty, which concerns legislative supremacy rather than royal personal liability.

Why It Matters in Research
This maxim is a threshold concept for any research touching sovereign immunity, Crown liability, or the historical development of administrative law in common law systems. Several navigational points are essential:
Historical sources use the maxim loosely. Bouvier reduces it to a single sentence on personal non-responsibility. Older treatises, including Blackstone's Commentaries (Book III) and early editions of Chitty on the Prerogatives of the Crown, carry far more analytical weight and should be consulted directly when tracing the doctrine's constitutional dimensions. Do not rely on dictionary treatments alone for doctrinal depth.
The maxim bridges royal prerogative and modern sovereign immunity. Researchers moving from English constitutional history into American law should note that the United States received something like this principle by inheritance — American sovereign immunity doctrine draws on the same conceptual root — but without a monarch, the doctrine was re-rationalized around the structural separateness of the government as sovereign. The maxim itself appears occasionally in early American cases as rhetorical support, but the American doctrine developed independently through judicial construction and eventually statute (Federal Tort Claims Act, 1946).
Ministerial responsibility is the living legacy. In Commonwealth jurisdictions and in constitutional scholarship, the more important descendant of the maxim is not immunity doctrine but the principle that ministers of the Crown are individually accountable to Parliament for Crown acts. This constitutional convention, not judicial doctrine, is where the maxim's energy went after the seventeenth-century constitutional settlements.
Post-1947 English law requires care with pre-1947 sources. A researcher reading equity or common law materials before the Crown Proceedings Act 1947 will encounter procedural forms — the petition of right, the monstrans de droit — that were the only mechanisms by which a subject could seek relief against the Crown. These forms assumed the maxim's operation and are incomprehensible without understanding it.

Historical Dictionary Support
Bouvier's entry is notably thin — a single sentence attributing the maxim's content to Austin's Jurisprudence — and should be treated as a signpost rather than an analysis. Bouvier correctly identifies the core: the king bears no legal responsibility. But the entry omits entirely the constitutional reinterpretation (ministerial responsibility), the procedural workarounds available to subjects, and any engagement with the maxim's contested history.
Austin's treatment in the Jurisprudence is more analytical, engaging the question of what it means for a sovereign to be subject to law at all. Dicey's Law of the Constitution, though later, is the more useful secondary source for researchers because Dicey traces the gap between the formal persistence of the maxim and the practical accountability mechanisms that developed around it.
The maxim itself is ancient — it appears in Bracton and is elaborated in Coke and Blackstone — but its meaning shifted substantially between the medieval period (where it reflected jurisdictional structure) and the post-1688 constitutional order (where it became a vehicle for ministerial accountability). Historical legal dictionaries across the nineteenth century tend to record the medieval and formalistic meaning without fully absorbing the post-1688 constitutional transformation.

Jurisdictional Note
In England and Wales, the Crown Proceedings Act 1947 is the operative statute, and the maxim survives mainly as a constitutional convention regarding ministerial responsibility. In the United States, sovereign immunity is governed by federal and state statutes (including the Federal Tort Claims Act) and judicial doctrine; the maxim is historical background, not operative law. Commonwealth jurisdictions vary in their Crown liability statutes but share the English conceptual inheritance.
