Magna Carta: The Great Charter of English Liberty

The Historical Context: King John and the Baronial Rebellion

Magna Carta was born from a crisis of royal misgovernment. King John’s reign (1199–1216) was marked by military catastrophe, fiscal exaction, and arbitrary rule. John lost Normandy to the French king Philip Augustus in 1204, then spent years attempting to reconquer his Continental possessions through increasingly burdensome taxation. He imposed scutage payments (payments in lieu of military service) at unprecedented frequency and levels, exploited feudal incidents such as reliefs and wardships to extract revenue, and sold justice through the payment of fines for access to the royal courts. His quarrel with Pope Innocent III over the appointment of the Archbishop of Canterbury led to the interdict of England (1208–1214), during which church services ceased and John confiscated ecclesiastical property.

The financial exactions culminated in the failed Bouvines campaign of 1214, after which a coalition of barons, angered by John’s arbitrary government and fiscal oppression, rose in rebellion. The barons entered London in May 1215, forcing John to negotiate. The King met the barons at Runnymede on the River Thames on June 15, 1215, where he placed his seal upon the Articles of the Barons, which were then issued as a formal charter—Magna Carta. The charter was less a forward-looking statement of constitutional principle than a feudal contract addressing specific grievances, but its implications would prove revolutionary.

The Key Clauses

The 1215 Magna Carta contained 63 clauses addressing a comprehensive array of grievances. Clause 39 became the most celebrated: “No free man shall be seized or imprisoned, or stripped of his rights or possessions, or outlawed or exiled, or deprived of his standing in any way, nor will we proceed with force against him, or send others to do so, except by the lawful judgment of his equals or by the law of the land.” This clause established the principle that no person could be punished without due process of law. It did not create trial by jury in its modern form—the “judgment of his peers” referred to the feudal right to be judged by one’s social equals—but it provided the foundation upon which the jury system would later be built.

Clause 40 declared: “To no one will we sell, to no one deny or delay right or justice.” This prohibition on the sale, denial, or delay of justice established the principle that courts must be accessible and that justice cannot be purchased. Clause 12 provided that no “scutage or aid” should be imposed without “the general consent of the kingdom,” creating the foundation for the principle of no taxation without representation. Clause 38 prohibited the use of royal authority alone to bring criminal accusations without credible witnesses. Clause 20 limited fines, requiring that they be proportionate to the offence. Clause 17 provided that ordinary civil pleas should follow the common pleas court rather than the King’s itinerant justices, anticipating the separation of the Court of Common Pleas.

Other clauses addressed the standardisation of weights and measures, the removal of fish weirs from rivers, the expulsion of foreign mercenaries, and the regulation of the royal forest. Clause 61, the security clause, established a council of twenty-five barons empowered to seize the King’s castles and lands if he violated the charter—a provision so radical that it effectively declared lawful rebellion against an errant sovereign.

The Immediate Aftermath and Reissues

Magna Carta did not bring peace. Pope Innocent III annulled the charter on August 24, 1215, declaring it “shameful and demeaning” and obtained under duress. England descended into civil war, and John died in October 1216 during the conflict. John’s nine-year-old son, Henry III, succeeded him, and the regency government reissued Magna Carta in 1216, omitting the most contentious clauses (including the security clause). A further reissue in 1217 incorporated a separate Charter of the Forest dealing with royal forest law. The definitive reissue came in 1225, when the eighteen-year-old Henry III confirmed the charter in exchange for a grant of taxation. This 1225 version, containing thirty-seven clauses, became the authoritative text that entered English law.

Edward I confirmed Magna Carta in 1297, ordering it distributed to sheriffs throughout the kingdom and read twice yearly in cathedrals. The Confirmatio Cartarum of 1297 enrolled the charter in the statute book, establishing it as part of the positive law of England. By the late Middle Ages, Magna Carta had become a foundational text, regularly invoked in parliamentary disputes with the Crown.

The 17th-Century Revival: Coke and the Petition of Right

Magna Carta’s most transformative period came in the 17th century, when it was revived and reinterpreted in the constitutional struggles between Parliament and the Stuart monarchs. Sir Edward Coke, the leading common lawyer of his age, transformed the charter from a medieval feudal document into a bulwark of English liberty. In his Institutes of the Lawes of England (1628–1644), Coke argued that Magna Carta was a declaration of the ancient common law and that “the law of the land” in clause 39 meant due process of law, including the right to habeas corpus and the right to a fair trial. Coke used Magna Carta to oppose royal impositions (taxation without parliamentary consent) and arbitrary imprisonment.

The Petition of Right (1628), drafted by Coke and other parliamentary leaders, invoked Magna Carta explicitly. It recited clause 39 and declared that no person should be imprisoned without cause shown, that martial law might not be imposed in peacetime, and that no taxes could be levied without parliamentary consent. Charles I accepted the Petition under duress but subsequently ignored it, a breach that deepened the crisis leading to the Civil War. Magna Carta was also invoked by the Levellers and other radical groups who argued that the charter’s principles extended to all Englishmen, not merely freemen—an interpretation that pointed toward universal rights.

Global Influence

Magna Carta’s influence on the United States Constitution is profound. The American colonists read Coke’s interpretation of clause 39 as protecting due process and trial by jury, rights incorporated into the Fifth, Sixth, and Seventh Amendments. The phrase “law of the land” in the original Constitution and in state constitutions echoes Magna Carta. The U.S. Supreme Court has cited Magna Carta in more than 170 decisions, most notably in the area of procedural due process. In Hurtado v. California (1884), the Court traced the origins of due process to Magna Carta’s pledge of judgment by “the law of the land.”

Internationally, Magna Carta influenced the Universal Declaration of Human Rights (1948), particularly Article 6 (right to recognition as a person before the law), Article 8 (right to an effective remedy), Article 9 (prohibition of arbitrary arrest), and Article 10 (right to a fair trial). It is inscribed on the UNESCO Memory of the World Register. The European Convention on Human Rights (1950) similarly reflects Magna Carta’s due process guarantees. Courts in Canada, Australia, India, and South Africa have cited Magna Carta in constitutional decisions.

Modern Legal Status

Only four clauses of Magna Carta remain on the statute book in England and Wales. Clause 1 guarantees the freedom of the English Church. Clause 13 (originally clause 9 of the 1225 version) confirms the liberties of the City of London. Clause 39 (originally clause 29) guarantees due process. Clause 40 (originally clause 30) prohibits the sale, denial, or delay of justice. The rest were repealed by the Statute Law Revision Act of 1863 and subsequent legislation.

Despite the extensive repeal, Magna Carta retains legal force. In R (UNISON) v Lord Chancellor (2017), the Supreme Court invoked clause 40 in holding that employment tribunal fees were unlawful because they impeded access to justice. Lord Reed observed that “the constitutional right of access to the courts is inherent in the rule of law” and traced that right to Magna Carta. Clause 29 has been cited in cases concerning the right to a fair trial, the principle of legality, and the independence of the judiciary. Magna Carta survives not merely as a historical artefact but as a living provision of English law, its ancient language embodying principles that continue to constrain the exercise of governmental power.
