Part 12 - Jurisdiction

Read Time: 20 minutes

Jurisdiction is the authority to govern, to judge, to make law — and the boundary within which that authority operates. Every court has a jurisdiction. Every law has a jurisdiction. Every institution that claims authority over a man or woman is claiming jurisdiction over them. Understanding what jurisdiction is, where it comes from, and how it is established — and challenged — is understanding one of the most fundamental questions in the legal world. Before any other question in a proceeding can be answered, this one must be: does this body have the authority to deal with this matter, in relation to this person, in this place, at this time?

What jurisdiction means

Fact

The word jurisdiction comes from the Latin — juris, of law, and dictio, a saying or speaking. Jurisdiction is, literally, the speaking of the law. The authority to declare what the law is and to apply it. A court without jurisdiction cannot hear a case. A law without jurisdiction cannot bind. An institution without jurisdiction cannot govern. Jurisdiction is the threshold question — the question that must be answered before anything else can proceed.

Jurisdiction has several dimensions. Subject matter jurisdiction — does this court or body have the authority to deal with this type of matter? Personal jurisdiction — does this court or body have authority over this particular man or woman? Territorial jurisdiction — does this law or court have authority in this place? And temporal jurisdiction — does this authority operate at this point in time, under the laws currently in force?

Observation

Each of these dimensions can be questioned. Each can be absent. A court that has subject matter jurisdiction but not personal jurisdiction cannot proceed against a particular man or woman. A law that applies within one territory does not automatically apply in another. An authority granted jurisdiction by statute operates only within the limits of that statute — and a statute that exceeds its constitutional authority is on ground that the hierarchy of law does not comfortably support.

Most men and women never ask about jurisdiction. They receive a letter, a summons, a demand, and engage with the substance — the debt, the charge, the claim — without ever asking the prior question: does this body have the authority to make this claim against me, in this capacity, in this context? That prior question — asked clearly, in writing, in honour — is often the most important question available.

How jurisdiction is established — and accepted

Fact

Jurisdiction is not simply asserted — it must be established. A court has jurisdiction over a matter because statute grants it, or because common law recognises it, or because the parties have agreed to submit to it. A court has jurisdiction over a person because they are within its territorial reach, or because they have consented to its jurisdiction, or because statute provides for it.

Observation

Consent to jurisdiction is one of the most significant and least understood forms of consent in the legal world. When a man or woman responds to a summons — when they appear, when they engage, when they answer the name called — they are, in that act, consenting to the jurisdiction of the court. They are accepting that this body has the authority to deal with this matter in relation to them. That acceptance may be the most consequential thing they do in the entire proceeding — and it happens before a single word of the case has been heard.

This is why the question of jurisdiction must be raised — if it is to be raised at all — at the very outset of any proceeding. Once a man or woman has engaged with the substance of the case, the question of jurisdiction becomes much harder to raise. Engaging with the merits is itself an implied acceptance of jurisdiction. The time to question whether the court has authority is before answering to the name — not after arguing the facts.

"The court's first question is always whether it has jurisdiction. Most defendants never ask the same question. They walk in, answer to the name, engage with the charge, and never notice that the threshold they crossed to do so was the most important one in the room."

Jurisdictions within jurisdictions

Fact

The United Kingdom does not have a single unified legal system. England and Wales share one jurisdiction. Scotland has a separate and distinct legal system — Scots law, developed differently from English common law, with its own courts, its own principles, and its own body of statute. Northern Ireland has its own jurisdiction. The Channel Islands and the Isle of Man are Crown Dependencies — not part of the United Kingdom, with their own legal systems, their own courts, and their own legislatures. A law that applies in England and Wales does not automatically apply in Scotland. A court in England has no jurisdiction in the Channel Islands.

But the division of jurisdiction does not stop at national boundaries. Jurisdictions exist within jurisdictions — nested, layered, each with its own rules, its own governance, and its own claim to authority within its specific domain.

The City of London — a jurisdiction within a jurisdiction

Fact

The City of London — the Square Mile — occupies approximately one square mile at the historic heart of Greater London. It is surrounded by London on all sides. And yet it is not governed by London. It is governed by itself.

The City of London Corporation is described by its own documentation as a sui generis local authority — one of a kind, in a class of its own. It is Britain's oldest local government, predating Parliament itself, holding city status by ancient prescriptive right rather than by letters patent. It has its own Lord Mayor — distinct from the Mayor of London who governs Greater London. It has its own courts. It has its own bylaws. And it has its own police force — the City of London Police, which has operated independently since 1839 and has no jurisdiction outside the Square Mile. When the Metropolitan Police was created in 1829, the City of London Corporation resisted any attempt to extend Metropolitan Police jurisdiction into the Square Mile. The boundary has held ever since.

Observation

The City of London Police wear a uniform that differs from every other police force in the United Kingdom — gold insignia where other forces use silver, a red and white tartan band on their headwear. The boundaries of the Square Mile are marked by cast iron dragon statues — the heraldic emblem of the City — standing at the historic entry points. You do not merely arrive in the City of London. You cross into it. The boundary is marked. The jurisdiction is announced.

Fact

The City of London Corporation has a democratic structure that exists nowhere else in the United Kingdom. It has two categories of voters — residents and businesses. Residents have one vote each. Businesses have votes allocated according to the number of employees they have within the Square Mile — one vote per five employees up to ten votes, with additional votes per fifty employees beyond that. The resident population of the Square Mile is approximately 8,600 people. The daily working population exceeds 500,000.

In the City of London, corporations vote. The financial institutions, the law firms, the banks, the trading houses — they nominate employees as voters and participate in the governance of the Square Mile. It is the only place in the United Kingdom where this remains the case. Everywhere else, the principle of one person one vote has been the rule since the great democratic reforms of the nineteenth and twentieth centuries. The City of London was specifically exempted. It resisted reform then. It resists it still.

Observation

The ward names of the City of London are worth noting. Bread Street. Candlewick. Cornhill. Cheapside. Medieval names — from a time before Parliament existed in anything like its current form. The governance of the Square Mile has remained, in its essential character, recognisable from that era. The Lord Mayor. The Court of Aldermen. The Court of Common Council. The livery companies — the ancient guilds of merchants and craftsmen whose membership lists form one of the three electoral registers used in City elections. The Square Mile does not merely have ancient privileges. It has maintained them, against repeated pressure, across centuries.

The City of London is the financial centre of the United Kingdom and one of the two or three most significant financial centres in the world. The Bank of England sits within it. Lloyd's of London. The London Stock Exchange. The headquarters of the major clearing banks. The offices of the largest law firms. All of this sits within a jurisdiction that governs itself, polices itself, votes through its corporations, and has maintained its unique legal status against every attempt at reform for centuries.

Philosophy

Whether the Square Mile's unique jurisdictional status — its ancient privileges, its corporate vote, its separate police force, its resistance to the democratic reforms applied everywhere else — is a historical curiosity or something more deliberate is a question the reader can sit with. What is observable is this: the most powerful concentration of financial and legal institutions in the country occupies a jurisdiction that has kept its own rules, by its own authority, since before the modern state existed. And the modern state has never successfully changed that.

Public and private jurisdiction

Observation

Part 4 of this series examined the distinction between the public and the private domains. That distinction maps directly onto jurisdiction. The public domain has its own jurisdiction — the statutory framework, the courts, the regulatory bodies, the administrative apparatus. The private domain has its own jurisdiction — contract, agreement, conscience, natural law. These are different jurisdictions, governing different relationships, applying different principles.

A man or woman who is operating in the private domain — who has not stepped into a public capacity, who is not engaged in commerce under a public licence, who is not acting as a legal person within the public framework — may not be within the jurisdiction of the public courts and regulatory bodies in the same way as one who has. The question of which domain a man or woman is in — and which jurisdiction therefore applies — is one of the most significant questions in this series.

Observation

Most institutions assume the public jurisdiction applies. They deal with persons — legal entities operating in the public domain — and assume that the man or woman they are writing to is that person, operating in that domain, subject to that jurisdiction. The man or woman who knows the difference between themselves and the person — who understands which domain they are in and can state it clearly — is engaging with the question of jurisdiction in a way that most people never do.

Courts de jure — and the impulse to build something new

Observation

A court de jure — in law, as it ought to be — is distinguished from a court de facto, which operates in practice but without the full legal authority that proper constitution requires. The distinction is ancient. It runs through the same common law tradition that produced Magna Carta and the Bill of Rights. A court properly constituted, with proper authority, with proper jurisdiction, judging by the law of the land — is a court de jure. An administrative body processing commercial obligations under the appearance of court authority is, in that characterisation, something else.

Fact

The grand jury — the most significant people's court in English legal history — was a genuine common law institution rooted in Magna Carta. It predated the trial jury. Twenty-three members drawn from the community would hear accusations and decide whether there was a case to answer — whether the evidence was sufficient to justify putting a man or woman on trial. The grand jury was the community's check on the state's power to prosecute. It could decline to indict. It could investigate matters on its own initiative. It stood between the individual and the full weight of the state's criminal apparatus.

It was abolished in England and Wales by the Criminal Justice Act 1948. It was not replaced with anything equivalent. It survives in the United States, where it is constitutionally protected at federal level. Its abolition removed the last institutional mechanism through which ordinary men and women — not judges, not officials, not professionals within the system — could independently decide whether a criminal prosecution was justified. The trial jury decides guilt or innocence after the case has been brought. The grand jury decided whether the case should be brought at all. These are different functions. One of them no longer exists here.

Observation

In recent years — particularly since 2020 — there has been a growing impulse among people who have lost confidence in the existing court system to establish alternative forums. People's tribunals. Common law courts. Grand jury proceedings modelled on the American system. The impulse is understandable. When the established institutions appear to be failing in their constitutional function — when administrative courts process commercial obligations under the appearance of justice, when juries are absent from most proceedings, when the clerk rather than the judge drives the outcome — the desire to build something that operates according to the principles the existing system claims but does not always honour is a natural response.

Alternative dispute resolution — arbitration and mediation — is a legitimate and growing area of law, fully authorised under the Arbitration Act 1996. Parties can agree to resolve their disputes outside the courts, before an arbitrator of their choosing, under rules they agree to, with a binding outcome. The Sikh Court, established at Lincoln's Inn in 2024, is one example — a voluntary arbitration and mediation body for the British Sikh community, operating alongside rather than against the court system, providing culturally informed resolution of civil and family disputes. It is authorised by statute. It carries real authority because the parties have genuinely consented to it.

Philosophy

The more ambitious projects — bodies that describe themselves as courts of law, that issue arrest warrants, that purport to try and convict public figures without their participation — have not produced enforceable outcomes. The authority of a court derives from its jurisdiction — from the framework that grants it the power to act and requires others to respond to its decisions. A body that lacks recognised authority to enforce its decisions cannot compel performance from those who do not choose to accept it. However sincerely convened, however carefully structured, however just its conclusions — without jurisdiction, it is a gathering, not a court.

This is not a reason to dismiss the impulse. The Court of Chancery itself grew from the petitions of ordinary men and women to the King's conscience — seeking remedy that the common law could not provide. The tradition of building structures outside the existing framework, when the existing framework fails, is as old as the common law itself. The question is not whether to build — but what to build, on what authority, with what foundation, and with what realistic understanding of what it can and cannot achieve.

A private members' association, governing its own members under its own rules, with genuine consent, within a framework the law recognises — carries more practical authority than a self-declared court that the existing system has no obligation to recognise. Understanding the difference between the two is part of understanding jurisdiction.

The calendar — a jurisdiction of its own

Fact

Jurisdiction operates in time as well as in place. Laws come into force at specific dates. Courts operate within specific legal frameworks that change over time. Rights and obligations arise at specific moments. The question of when — what date, what year, what calendar — is not a trivial one. Time itself, in the legal world, is a jurisdiction.

The calendar most of the world uses today — the Gregorian calendar — was introduced by Pope Gregory XIII in 1582, through a papal bull called Inter gravissimas — meaning "among the most serious concerns." Its stated purpose was to correct errors in the Julian calendar which had caused the date of Easter to drift from its astronomical alignment. Ten days were simply removed — October 4, 1582 was followed immediately by October 15. Time was not observed. It was decreed. By a pope. Through a legal instrument.

Observation

Pope Gregory XIII was, before his papacy, a doctor of both civil and canon law. He taught jurisprudence. His intellectual formation was legal — and the calendar he introduced was issued not as a scientific document but as a legal one. A papal bull carries the full authority of the Holy See. The Gregorian calendar was adopted, territory by territory, as an act of political and religious submission. Catholic nations adopted it in 1582. Protestant nations resisted for over a century — Britain did not adopt it until 1752, when Parliament passed the Calendar (New Style) Act and eleven days were removed from September of that year. September 2 was followed by September 14. Time, again, was not observed. It was legislated.

What year is it?

Fact

The answer depends entirely on which jurisdiction's calendar you are operating within. The Gregorian calendar says 2026. But that is not the only answer — and it is far from a universal one.

Gregorian — 2026. The civil calendar used by most countries for administrative and commercial purposes. Counts years from the estimated birth of Jesus Christ — Anno Domini, the Year of the Lord. Introduced by papal bull in 1582.

Hebrew — 5786/5787. A lunisolar calendar used for Jewish religious observances. Counts from the traditional date of creation, calculated from the Hebrew scriptures. The new year — Rosh Hashanah — falls in autumn by the Gregorian calendar.

Islamic — 1447/1448 AH. A purely lunar calendar. AH stands for Anno Hegirae — the Year of the Hijra, counting from the Prophet Muhammad's emigration from Mecca to Medina in 622 AD. A shorter year than the Gregorian — the Islamic calendar moves through the seasons over decades.

Chinese — year of the Wood Snake. A lunisolar calendar running in sixty-year cycles. The Chinese year count differs depending on the epoch used — variously listed as the 4720s depending on the system applied.

Buddhist — 2568/2569. Counts from the death or enlightenment of the Buddha, depending on the tradition. Used in Thailand, Cambodia, Sri Lanka, and other Buddhist nations alongside the Gregorian.

Ethiopian — 2018/2019. Ethiopia uses its own calendar — thirteen months, seven to eight years behind the Gregorian. Ethiopia celebrated its millennium in 2007 by Gregorian reckoning.

Julian — 13 days behind Gregorian. Still used by some Eastern Orthodox churches for religious purposes. The calendar Britain used before 1752.

Observation

There is no universal agreement on what year it is. There is a dominant agreement — the Gregorian system, adopted by most nations for civil and commercial purposes because it provides a common framework for international trade, law, and administration. But dominant is not universal. The year it counts from — the estimated birth of a particular figure in a particular religious tradition — is not a scientific datum. It is a theological and political choice, made by a specific institution at a specific moment in history, and accepted by the world's legal and commercial systems on that basis. The year 2026, on every document, every contract, every court filing — is a date within that framework.

The months — evidence written in the names

Fact

The names of the months carry within them evidence of a calendar that was rearranged — and never corrected. The last four months tell the story plainly.

September — from the Latin septem, seven. September is the ninth month. It was the seventh.

October — from the Latin octo, eight. October is the tenth month. It was the eighth.

November — from the Latin novem, nine. November is the eleventh month. It was the ninth.

December — from the Latin decem, ten. December is the twelfth month. It was the tenth.

The original Roman calendar began in March — Martius, named for Mars, the god of war, when military campaigning resumed after winter. The year began in spring. January and February were added later — moved to the beginning by Julius Caesar's reform in 46 BC — pushing September through December from their numbered positions into positions two months later, where they have remained ever since, carrying names that no longer correspond to where they fall.

Observation

July and August were not always called July and August. They were Quintilis — fifth — and Sextilis — sixth. They were renamed after Julius Caesar and Augustus Caesar respectively — by a Roman senate that wished to honour its rulers by attaching their names to the months they were born in. The calendar was used to commemorate power — to write the names of emperors into the fabric of time itself, so that every year, in every document, in every conversation, their names would be spoken. The calendar we use is a document of history. Its names are wrong by their own etymology. Its year count begins from a religious choice. Its structure was imposed by decree.

The number thirteen — and the calendar it displaced

Fact

The moon completes its cycle approximately every 29.5 days. Thirteen such cycles fit into a solar year with greater precision than twelve. A thirteen-month lunar calendar of 28 days each — 364 days, with one or two intercalary days — tracks both the moon and the solar year more accurately than the twelve-month Gregorian system. Many ancient cultures used a thirteen-month calendar. The Celts. The ancient Egyptians. The Maya. The thirteen-month structure is mathematically closer to the natural rhythms of the moon and the year than the system that replaced it.

Observation

The number thirteen has an unusual cultural status in the Western world. Unlucky. To be avoided. Buildings without a thirteenth floor. Thirteen at a table. Friday the thirteenth. The superstition is so embedded that most people who hold it cannot say where it came from. Thirteen is the number of lunar months in a solar year. The replacement of the thirteen-month lunar calendar by a twelve-month solar calendar administered by Roman and then Catholic authority — and the subsequent cultural stigmatisation of the number thirteen — may or may not be connected. The reader can hold that question for themselves.

An International Fixed Calendar — thirteen months of exactly 28 days each, with one additional year-day — was proposed in the early twentieth century and considered by the League of Nations. It was rejected. The Gregorian calendar, with its irregular months, its uneven distribution of days, and its displacement of month names from their original meanings, was retained. The system was not replaced by a more accurate or more rational one. It was kept. Because the system is not primarily about accuracy. It is about jurisdiction — about who controls the framework within which time is measured, documents are dated, and legal obligations arise.

Dating documents — and what it implies

Observation

Every document in the legal and commercial world carries a date. Contracts are dated. Court filings are dated. Correspondence is dated. Statutes come into force on specific dates. Rights and obligations arise, and expire, at specific moments within the Gregorian calendar framework.

When a man or woman dates a document — writes "25 August 2026" on a letter, a contract, a court filing — they are placing themselves within the Gregorian calendar system. They are using its framework, its epoch, its structure, as the reference point for the legal significance of what they are doing. They are, in a small but real sense, operating within the jurisdiction that the Gregorian calendar represents — the jurisdiction of the system that created it, maintains it, and uses it as the temporal framework for every legal and commercial obligation it administers.

Observation

Whether this constitutes a meaningful act of joinder — whether dating a document in the Gregorian system is a conscious acceptance of the jurisdiction of the institutions that created and maintain that system — is a question at the more philosophical end of this series. What is grounded and observable is this: the calendar is not neutral. It was created by specific institutions. It carries specific authority. It was imposed through specific legal instruments. And every document dated within it is dated within a framework those institutions designed, for purposes that included the administration of jurisdiction over the men and women within it.

Some men and women, aware of this, choose to date their private correspondence differently — by the lunar cycle, by a non-Gregorian reference, or with an explicit notation that the date is given for reference only and does not constitute acceptance of any particular jurisdiction. Whether this has legal consequence depends entirely on context. What it has is meaning — the meaning of a man or woman who knows what framework they are using, and has made a conscious choice about it, rather than one who uses it by default without ever having been told what it is.

Jurisdiction — the thread through the series

Philosophy

Jurisdiction is the thread that runs through every part of this series without always being named. Which domain are you in? Which law applies? Which court has authority? Which framework governs? These are all questions of jurisdiction.

The hierarchy of law — Part 6 — is a map of which jurisdiction has precedence over which. Natural law has jurisdiction everywhere. Common law has jurisdiction on the land. Admiralty has jurisdiction at sea — and perhaps, as Part 6 observed, has extended its reach to the land in ways that were never consented to. Statute has jurisdiction within its own framework — over persons who have consented to it, operating in the domain it governs.

Consent — Part 7 — is the mechanism through which jurisdiction is accepted. Appearing in court, answering to the name, engaging with the proceedings — these are acts of consent to jurisdiction. Understanding that they are is the beginning of understanding that jurisdiction is something that is given, not simply taken. It requires acceptance. And acceptance that is not conscious, not informed, not genuinely free — is the kind of consent this series has spent eleven parts examining.

The calendar — the temporal dimension of jurisdiction — is the frame within which every legal act takes place. Knowing who made the frame, why they made it, what it replaced, and what operating within it implies — is knowing one more layer of what the legal world actually is, beneath the surface of what it presents itself to be.

"Before the substance of any claim, any charge, any proceeding — there is a prior question. Does this body have the authority to deal with this matter, in relation to this person, in this place, at this time? Most people never ask it. The ones who do are standing on different ground from the moment they walk through the door."
