But happily for us of this island, the British constitution has long remained, and I trust will long continue, a standing exception to the truth of this observation. For, as with us the executive power of the laws is lodged in a single person, they have all the advantages of strength and dispatch, that are to be found in the most absolute monarchy; and, as the legislature of the kingdom is entrusted to three distinct powers, entirely independent of each other; first, the king; secondly, the lords spiritual and temporal, which is an aristocratical assembly of persons selected for their piety, their birth, their wisdom, their valour, or their property; and, thirdly, the house of commons, freely chosen by the people from among themselves, which makes it a kind of democracy; as this aggregate body, actuated by different springs, and attentive to different interests, composes the British parliament, and has the supreme disposal of every thing; there can no inconvenience be attempted by either of the three branches, but will be withstood by one of the other two; each branch being armed with a negative power, sufficient to repel any innovation which it shall think inexpedient or dangerous.

Here then is lodged the sovereignty of the British constitution; and lodged as beneficially as is possible for society. For in no other shape could we be so certain of finding the three great qualities of government so well and so happily united. If the supreme power were lodged in any one of the three branches separately, we must be exposed to the inconveniences of either absolute monarchy, aristocracy, or democracy; and so want two of the three principal ingredients of good polity, either virtue, wisdom, or power. If it were lodged in any two of the branches; for instance, in the king and house of lords, our laws might be providently made, and well executed, but they might not always have the good of the people in view: if lodged in the king and commons, we should want that circumspection and mediatory caution, which the wisdom of the peers is to afford: if the supreme rights of legislature were lodged in the two houses only, and the king had no negative upon their proceedings, they might be tempted to encroach upon the royal prerogative, or perhaps to abolish the kingly office, and thereby weaken (if not totally destroy) the strength of the executive power. But the constitutional government of this island is so admirably tempered and compounded, that nothing can endanger or hurt it, but destroying the equilibrium of power between one branch of the legislature and the rest. For if ever it should happen that the independence of any one of the three should be lost, or that it should become subservient to the views of either of the other two, there would soon be an end of our constitution. The legislature would be changed from that, which was originally set up by the general consent and fundamental act of the society; and such a change, however effected, is according to Mr Locke[h] (who perhaps carries his theory too far) at once an entire dissolution of the bands of government; and the people would be reduced to a state of anarchy, with liberty to constitute to themselves a new legislative power.

Having thus cursorily considered the three usual species of government, and our own singular constitution, selected and compounded from them all, I proceed to observe, that, as the power of making laws constitutes the supreme authority, so wherever the supreme authority in any state resides, it is the right of that authority to make laws; that is, in the words of our definition, to prescribe the rule of civil action. And this may be discovered from the very end and institution of civil states. For a state is a collective body, composed of a multitude of individuals, united for their safety and convenience, and intending to act together as one man. If it therefore is to act as one man, it ought to act by one uniform will. But, inasmuch as political communities are made up of many natural persons, each of whom has his particular will and inclination, these several wills cannot by any natural union be joined together, or tempered and disposed into a lasting harmony, so as to constitute and produce that one uniform will of the whole. It can therefore be no otherwise produced than by a political union; by the consent of all persons to submit their own private wills to the will of one man, or of one or more assemblies of men, to whom the supreme authority is entrusted: and this will of that one man, or assemblage of men, is in different states, according to their different constitutions, understood to be law.

Thus far as to the right of the supreme power to make laws; but farther, it is it's duty likewise. For since the respective members are bound to conform themselves to the will of the state, it is expedient that they receive directions from the state declaratory of that it's will. But since it is impossible, in so great a multitude, to give injunctions to every particular man, relative to each particular action, therefore the state establishes general rules, for the perpetual information and direction of all persons in all points, whether of positive or negative duty. And this, in order that every man may know what to look upon as his own, what as another's; what absolute and what relative duties are required at his hands; what is to be esteemed honest, dishonest, or indifferent; what degree every man retains of his natural liberty; what he has given up as the price of the benefits of society; and after what manner each person is to moderate the use and exercise of those rights which the state assigns him, in order to promote and secure the public tranquillity.

From what has been advanced, the truth of the former branch of our definition, is (I trust) sufficiently evident; that "municipal law is a rule of civil conduct prescribed by the supreme power in a state." I proceed now to the latter branch of it; that it is a rule so prescribed, "commanding what is right, and prohibiting what is wrong."

Now in order to do this completely, it is first of all necessary that the boundaries of right and wrong be established and ascertained by law. And when this is once done, it will follow of course that it is likewise the business of the law, considered as a rule of civil conduct, to enforce these rights and to restrain or redress these wrongs. It remains therefore only to consider in what manner the law is said to ascertain the boundaries of right and wrong; and the methods which it takes to command the one and prohibit the other.

For this purpose every law may be said to consist of several parts: one, declaratory; whereby the rights to be observed, and the wrongs to be eschewed, are clearly defined and laid down: another, directory, whereby the subject is instructed and enjoined to observe those rights, and to abstain from the commission of those wrongs: a third, remedial; whereby a method is pointed out to recover a man's private rights, or redress his private wrongs: to which may be added a fourth, usually termed the sanction, or vindicatory branch of the law; whereby it is signified what evil or penalty shall be incurred by such as commit any public wrongs, and transgress or neglect their duty.

With regard to the first of these, the declaratory part of the municipal law, this depends not so much upon the law of revelation or of nature, as upon the wisdom and will of the legislator. This doctrine, which before was slightly touched, deserves a more particular explication. Those rights then which God and nature have established, and are therefore called natural rights, such as are life and liberty, need not the aid of human laws to be more effectually invested in every man than they are; neither do they receive any additional strength when declared by the municipal laws to be inviolable. On the contrary, no human legislature has power to abridge or destroy them, unless the owner shall himself commit some act that amounts to a forfeiture. Neither do divine or natural duties (such as, for instance, the worship of God, the maintenance of children, and the like) receive any stronger sanction from being also declared to be duties by the law of the land. The case is the same as to crimes and misdemesnors, that are forbidden by the superior laws, and therefore stiled mala in se, such as murder, theft, and perjury; which contract no additional turpitude from being declared unlawful by the inferior legislature. For that legislature in all these cases acts only, as was before observed, in subordination to the great lawgiver, transcribing and publishing his precepts. So that, upon the whole, the declaratory part of the municipal law has no force or operation at all, with regard to actions that are naturally and intrinsically right or wrong.

But with regard to things in themselves indifferent, the case is entirely altered. These become either right or wrong, just or unjust, duties or misdemesnors, according as the municipal legislator sees proper, for promoting the welfare of the society, and more effectually carrying on the purposes of civil life. Thus our own common law has declared, that the goods of the wife do instantly upon marriage become the property and right of the husband; and our statute law has declared all monopolies a public offence: yet that right, and this offence, have no foundation in nature; but are merely created by the law, for the purposes of civil society. And sometimes, where the thing itself has it's rise from the law of nature, the particular circumstances and mode of doing it become right or wrong, as the laws of the land shall direct. Thus, for instance, in civil duties; obedience to superiors is the doctrine of revealed as well as natural religion: but who those superiors shall be, and in what circumstances, or to what degrees they shall be obeyed, is the province of human laws to determine. And so, as to injuries or crimes, it must be left to our own legislature to decide, in what cases the seising another's cattle shall amount to the crime of robbery; and where it shall be a justifiable action, as when a landlord takes them by way of distress for rent.

Thus much for the declaratory part of the municipal law: and the directory stands much upon the same footing; for this virtually includes the former, the declaration being usually collected from the direction. The law that says, "thou shalt not steal," implies a declaration that stealing is a crime. And we have seen that, in things naturally indifferent, the very essence of right and wrong depends upon the direction of the laws to do or to omit it.

The remedial part of a law is so necessary a consequence of the former two, that laws must be very vague and imperfect without it. For in vain would rights be declared, in vain directed to be observed, if there were no method of recovering and asserting those rights, when wrongfully withheld or invaded. This is what we mean properly, when we speak of the protection of the law. When, for instance, the declaratory part of the law has said "that the field or inheritance, which belonged to Titius's father, is vested by his death in Titius;" and the directory part has "forbidden any one to enter on another's property without the leave of the owner;" if Gaius after this will presume to take possession of the land, the remedial part of the law will then interpose it's office; will make Gaius restore the possession to Titius, and also pay him damages for the invasion.

With regard to the sanction of laws, or the evil that may attend the breach of public duties; it is observed, that human legislators have for the most part chosen to make the sanction of their laws rather vindicatory than remuneratory, or to consist rather in punishments, than in actual particular rewards. Because, in the first place, the quiet enjoyment and protection of all our civil rights and liberties, which are the sure and general consequence of obedience to the municipal law, are in themselves the best and most valuable of all rewards. Because also, were the exercise of every virtue to be enforced by the proposal of particular rewards, it were impossible for any state to furnish stock enough for so profuse a bounty. And farther, because the dread of evil is a much more forcible principle of human actions than the prospect of good[i]. For which reasons, though a prudent bestowing of rewards is sometimes of exquisite use, yet we find that those civil laws, which enforce and enjoin our duty, do seldom, if ever, propose any privilege or gift to such as obey the law; but do constantly come armed with a penalty denounced against transgressors, either expressly defining the nature and quantity of the punishment, or else leaving it to the discretion of the judges, and those who are entrusted with the care of putting the laws in execution.

Of all the parts of a law the most effectual is the vindicatory. For it is but lost labour to say, "do this, or avoid that," unless we also declare, "this shall be the consequence of your noncompliance." We must therefore observe, that the main strength and force of a law consists in the penalty annexed to it. Herein is to be found the principal obligation of human laws.

Legislators and their laws are said to compel and oblige; not that by any natural violence they so constrain a man, as to render it impossible for him to act otherwise than as they direct, which is the strict sense of obligation: but because, by declaring and exhibiting a penalty against offenders, they bring it to pass that no man can easily choose to transgress the law; since, by reason of the impending correction, compliance is in a high degree preferable to disobedience. And, even where rewards are proposed as well as punishments threatened, the obligation of the law seems chiefly to consist in the penalty: for rewards, in their nature, can only persuade and allure; nothing is compulsory but punishment.

It is held, it is true, and very justly, by the principal of our ethical writers, that human laws are binding upon mens consciences. But if that were the only, or most forcible obligation, the good only would regard the laws, and the bad would set them at defiance. And, true as this principle is, it must still be understood with some restriction. It holds, I apprehend, as to rights; and that, when the law has determined the field to belong to Titius, it is matter of conscience no longer to withhold or to invade it. So also in regard to natural duties, and such offences as are mala in se: here we are bound in conscience, because we are bound by superior laws, before those human laws were in being, to perform the one and abstain from the other. But in relation to those laws which enjoin only positive duties, and forbid only such things as are not mala in se but mala prohibita merely, annexing a penalty to noncompliance, here I apprehend conscience is no farther concerned, than by directing a submission to the penalty, in case of our breach of those laws: for otherwise the multitude of penal laws in a state would not only be looked upon as an impolitic, but would also be a very wicked thing; if every such law were a snare for the conscience of the subject. But in these cases the alternative is offered to every man; "either abstain from this, or submit to such a penalty;" and his conscience will be clear, whichever side of the alternative he thinks proper to embrace. Thus, by the statutes for preserving the game, a penalty is denounced against every unqualified person that kills a hare. Now this prohibitory law does not make the transgression a moral offence: the only obligation in conscience is to submit to the penalty if levied.

I have now gone through the definition laid down of a municipal law; and have shewn that it is "a rule—of civil conduct—prescribed—by the supreme power in a state—commanding what is right, and prohibiting what is wrong:" in the explication of which I have endeavoured to interweave a few useful principles, concerning the nature of civil government, and the obligation of human laws. Before I conclude this section, it may not be amiss to add a few observations concerning the interpretation of laws.

When any doubt arose upon the construction of the Roman laws, the usage was to state the case to the emperor in writing, and take his opinion upon it. This was certainly a bad method of interpretation. To interrogate the legislature to decide particular disputes, is not only endless, but affords great room for partiality and oppression. The answers of the emperor were called his rescripts, and these had in succeeding cases the force of perpetual laws; though they ought to be carefully distinguished, by every rational civilian, from those general constitutions, which had only the nature of things for their guide. The emperor Macrinus, as his historian Capitolinus informs us, had once resolved to abolish these rescripts, and retain only the general edicts; he could not bear that the hasty and crude answers of such princes as Commodus and Caracalla should be reverenced as laws. But Justinian thought otherwise[k], and he has preserved them all. In like manner the canon laws, or decretal epistles of the popes, are all of them rescripts in the strictest sense. Contrary to all true forms of reasoning, they argue from particulars to generals.

The fairest and most rational method to interpret the will of the legislator, is by exploring his intentions at the time when the law was made, by signs the most natural and probable. And these signs are either the words, the context, the subject matter, the effects and consequence, or the spirit and reason of the law. Let us take a short view of them all.

1. Words are generally to be understood in their usual and most known signification; not so much regarding the propriety of grammar, as their general and popular use. Thus the law mentioned by Puffendorf[l], which forbad a layman to lay hands on a priest, was adjudged to extend to him, who had hurt a priest with a weapon. Again; terms of art, or technical terms, must be taken according to the acceptation of the learned in each art, trade, and science. So in the act of settlement, where the crown of England is limited "to the princess Sophia, and the heirs of her body, being protestants," it becomes necessary to call in the assistance of lawyers, to ascertain the precise idea of the words "heirs of her body;" which in a legal sense comprize only certain of her lineal descendants. Lastly, where words are clearly repugnant in two laws, the later law takes place of the elder: leges posteriores priores contrarias abrogant is a maxim of universal law, as well as of our own constitutions. And accordingly it was laid down by a law of the twelve tables at Rome, quod populus postremum jussit, id jus ratum esto.

2. If words happen to be still dubious, we may establish their meaning from the context; with which it may be of singular use to compare a word, or a sentence, whenever they are ambiguous, equivocal, or intricate. Thus the proeme, or preamble, is often called in to help the construction of an act of parliament. Of the same nature and use is the comparison of a law with other laws, that are made by the same legislator, that have some affinity with the subject, or that expressly relate to the same point. Thus, when the law of England declares murder to be felony without benefit of clergy, we must resort to the same law of England to learn what the benefit of clergy is: and, when the common law censures simoniacal contracts, it affords great light to the subject to consider what the canon law has adjudged to be simony.

3. As to the subject matter, words are always to be understood as having a regard thereto; for that is always supposed to be in the eye of the legislator, and all his expressions directed to that end. Thus, when a law of our Edward III. forbids all ecclesiastical persons to purchase provisions at Rome, it might seem to prohibit the buying of grain and other victual; but when we consider that the statute was made to repress the usurpations of the papal see, and that the nominations to vacant benefices by the pope were called provisions, we shall see that the restraint is intended to be laid upon such provisions only.

4. As to the effects and consequence, the rule is, where words bear either none, or a very absurd signification, if literally understood, we must a little deviate from the received sense of them. Therefore the Bolognian law, mentioned by Puffendorf[m], which enacted "that whoever drew blood in the streets should be punished with the utmost severity," was held after long debate not to extend to the surgeon, who opened the vein of a person that fell down in the street with a fit.

5. But, lastly, the most universal and effectual way of discovering the true meaning of a law, when the words are dubious, is by considering the reason and spirit of it; or the cause which moved the legislator to enact it. For when this reason ceases, the law itself ought likewise to cease with it. An instance of this is given in a case put by Cicero, or whoever was the author of the rhetorical treatise inscribed to Herennius[n]. There was a law, that those who in a storm forsook the ship should forfeit all property therein; and the ship and lading should belong entirely to those who staid in it. In a dangerous tempest all the mariners forsook the ship, except only one sick passenger, who by reason of his disease was unable to get out and escape. By chance the ship came safe to port. The sick man kept possession and claimed the benefit of the law. Now here all the learned agree, that the sick man is not within the reason of the law; for the reason of making it was, to give encouragement to such as should venture their lives to save the vessel: but this is a merit, which he could never pretend to, who neither staid in the ship upon that account, nor contributed any thing to it's preservation.

From this method of interpreting laws, by the reason of them, arises what we call equity; which is thus defined by Grotius[o], "the correction of that, wherein the law (by reason of its universality) is deficient." For since in laws all cases cannot be foreseen or expressed, it is necessary, that when the general decrees of the law come to be applied to particular cases, there should be somewhere a power vested of excepting those circumstances, which (had they been foreseen) the legislator himself would have excepted. And these are the cases, which, as Grotius expresses it, "lex non exacte definit, sed arbitrio boni viri permittit."

Equity thus depending, essentially, upon the particular circumstances of each individual case, there can be no established rules and fixed precepts of equity laid down, without destroying it's very essence, and reducing it to a positive law. And, on the other hand, the liberty of considering all cases in an equitable light must not be indulged too far, lest thereby we destroy all law, and leave the decision of every question entirely in the breast of the judge. And law, without equity, tho' hard and disagreeable, is much more desirable for the public good, than equity without law; which would make every judge a legislator, and introduce most infinite confusion; as there would then be almost as many different rules of action laid down in our courts, as there are differences of capacity and sentiment in the human mind.

Section the third.
Of the LAWS of ENGLAND.

When I call these parts of our law leges non scriptae, I would not be understood as if all those laws were at present merely oral, or communicated from the former ages to the present solely by word of mouth. It is true indeed that, in the profound ignorance of letters which formerly overspread the whole western world, all laws were intirely traditional, for this plain reason, that the nations among which they prevailed had but little idea of writing. Thus the British as well as the Gallic druids committed all their laws as well as learning to memory[a]; and it is said of the primitive Saxons here, as well as their brethren on the continent, that leges sola memoria et usu retinebant[b]. But with us at present the monuments and evidences of our legal customs are contained in the records of the several courts of justice, in books of reports and judicial decisions, and in the treatises of learned sages of the profession, preserved and handed down to us from the times of highest antiquity. However I therefore stile these parts of our law leges non scriptae, because their original institution and authority are not set down in writing, as acts of parliament are, but they receive their binding power, and the force of laws, by long and immemorial usage, and by their universal reception throughout the kingdom. In like manner as Aulus Gellius defines the jus non scriptum to be that, which is "tacito et illiterato hominum consensu et moribus expressum."

Our antient lawyers, and particularly Fortescue[c], insist with abundance of warmth, that these customs are as old as the primitive Britons, and continued down, through the several mutations of government and inhabitants, to the present time, unchanged and unadulterated. This may be the case as to some; but in general, as Mr Selden in his notes observes, this assertion must be understood with many grains of allowance; and ought only to signify, as the truth seems to be, that there never was any formal exchange of one system of laws for another: though doubtless by the intermixture of adventitious nations, the Romans, the Picts, the Saxons, the Danes, and the Normans, they must have insensibly introduced and incorporated many of their own customs with those that were before established: thereby in all probability improving the texture and wisdom of the whole, by the accumulated wisdom of divers particular countries. Our laws, saith lord Bacon[d], are mixed as our language: and as our language is so much the richer, the laws are the more complete.

And indeed our antiquarians and first historians do all positively assure us, that our body of laws is of this compounded nature. For they tell us, that in the time of Alfred the local customs of the several provinces of the kingdom were grown so various, that he found it expedient to compile his dome-book or liber judicialis, for the general use of the whole kingdom. This book is said to have been extant so late as the reign of king Edward the fourth, but is now unfortunately lost. It contained, we may probably suppose, the principal maxims of the common law, the penalties for misdemesnors, and the forms of judicial proceedings. Thus much may at least be collected from that injunction to observe it, which we find in the laws of king Edward the elder, the son of Alfred[e]. "Omnibus qui reipublicae praesunt, etiam atque etiam mando, ut omnibus aequos se praebeant judices, perinde ac in judiciali libro (Saxonice, Anglo-Saxon: dom-bec) scriptum habetur; nec quicquam formident quin jus commune (Saxonice, Anglo-Saxon: folcrihte) audacter libereque dicant."

But the irruption and establishment of the Danes in England which followed soon after, introduced new customs and caused this code of Alfred in many provinces to fall into disuse; or at least to be mixed and debased with other laws of a coarser alloy. So that about the beginning of the eleventh century there were three principal systems of laws prevailing in different districts. 1. The Mercen-Lage, or Mercian laws, which were observed in many of the midland counties, and those bordering on the principality of Wales; the retreat of the antient Britons; and therefore very probably intermixed with the British or Druidical customs. 2. The West-Saxon-Lage, or laws of the west Saxons, which obtained in the counties to the south and west of the island, from Kent to Devonshire. These were probably much the same with the laws of Alfred abovementioned, being the municipal law of the far most considerable part of his dominions, and particularly including Berkshire, the seat of his peculiar residence. 3. The Dane-Lage, or Danish law, the very name of which speaks it's original and composition. This was principally maintained in the rest of the midland counties, and also on the eastern coast, the seat of that piratical people. As for the very northern provinces, they were at that time under a distinct government[f].

Out of these three laws, Roger Hoveden[g] and Ranulphus Cestrensis[h] inform us, king Edward the confessor extracted one uniform law or digest of laws, to be observed throughout the whole kingdom; though Hoveden and the author of an old manuscript chronicle[i] assure us likewise, that this work was projected and begun by his grandfather king Edgar. And indeed a general digest of the same nature has been constantly found expedient, and therefore put in practice by other great nations, formed from an assemblage of little provinces, governed by peculiar customs. As in Portugal, under king Edward, about the beginning of the fifteenth century[k]. In Spain under Alonzo X, who about the year 1250 executed the plan of his father St. Ferdinand, and collected all the provincial customs into one uniform law, in the celebrated code entitled las partidas[l]. And in Sweden about the same aera, a universal body of common law was compiled out of the particular customs established by the laghman of every province, and intitled the land's lagh, being analogous to the common law of England[m].

Both these undertakings, of king Edgar and Edward the confessor, seem to have been no more than a new edition, or fresh promulgation, of Alfred's code or dome-book, with such additions and improvements as the experience of a century and an half had suggested. For Alfred is generally stiled by the same historians the legum Anglicanarum conditor, as Edward the confessor is the restitutor. These however are the laws which our histories so often mention under the name of the laws of Edward the confessor; which our ancestors struggled so hardly to maintain, under the first princes of the Norman line; and which subsequent princes so frequently promised to keep and to restore, as the most popular act they could do, when pressed by foreign emergencies or domestic discontents. These are the laws, that so vigorously withstood the repeated attacks of the civil law; which established in the twelfth century a new Roman empire over most of the states on the continent: states that have lost, and perhaps upon that account, their political liberties; while the free constitution of England, perhaps upon the same account, has been rather improved than debased. These, in short, are the laws which gave rise and original to that collection of maxims and customs, which is now known by the name of the common law. A name either given to it, in contradistinction to other laws, as the statute law, the civil law, the law merchant, and the like; or, more probably, as a law common to all the realm, the jus commune or folcright mentioned by king Edward the elder, after the abolition of the several provincial customs and particular laws beforementioned.

But though this is the most likely foundation of this collection of maxims and customs, yet the maxims and customs, so collected, are of higher antiquity than memory or history can reach: nothing being more difficult than to ascertain the precise beginning and first spring of an antient and long established custom. Whence it is that in our law the goodness of a custom depends upon it's having been used time out of mind; or, in the solemnity of our legal phrase, time whereof the memory of man runneth not to the contrary. This it is that gives it it's weight and authority; and of this nature are the maxims and customs which compose the common law, or lex non scripta, of this kingdom.

This unwritten, or common, law is properly distinguishable into three kinds: 1. General customs; which are the universal rule of the whole kingdom, and form the common law, in it's stricter and more usual signification. 2. Particular customs; which for the most part affect only the inhabitants of particular districts. 3. Certain particular laws; which by custom are adopted and used by some particular courts, of pretty general and extensive jurisdiction.

I. As to general customs, or the common law, properly so called; this is that law, by which proceedings and determinations in the king's ordinary courts of justice are guided and directed. This, for the most part, settles the course in which lands descend by inheritance; the manner and form of acquiring and transferring property; the solemnities and obligation of contracts; the rules of expounding wills, deeds, and acts of parliament; the respective remedies of civil injuries; the several species of temporal offences, with the manner and degree of punishment; and an infinite number of minuter particulars, which diffuse themselves as extensively as the ordinary distribution of common justice requires. Thus, for example, that there shall be four superior courts of record, the chancery, the king's bench, the common pleas, and the exchequer;—that the eldest son alone is heir to his ancestor;—that property may be acquired and transferred by writing;—that a deed is of no validity unless sealed;—that wills shall be construed more favorably, and deeds more strictly;—that money lent upon bond is recoverable by action of debt;—that breaking the public peace is an offence, and punishable by fine and imprisonment;—all these are doctrines that are not set down in any written statute or ordinance, but depend merely upon immemorial usage, that is, upon common law, for their support.

Some have divided the common law into two principal grounds or foundations: 1. established customs; such as that where there are three brothers, the eldest brother shall be heir to the second, in exclusion of the youngest: and 2. established rules and maxims; as, "that the king can do no wrong, that no man shall be bound to accuse himself," and the like. But I take these to be one and the same thing. For the authority of these maxims rests entirely upon general reception and usage; and the only method of proving, that this or that maxim is a rule of the common law, is by shewing that it hath been always the custom to observe it.

But here a very natural, and very material, question arises: how are these customs or maxims to be known, and by whom is their validity to be determined? The answer is, by the judges in the several courts of justice. They are the depositary of the laws; the living oracles, who must decide in all cases of doubt, and who are bound by an oath to decide according to the law of the land. Their knowlege of that law is derived from experience and study; from the "viginti annorum lucubrationes," which Fortescue[n] mentions; and from being long personally accustomed to the judicial decisions of their predecessors. And indeed these judicial decisions are the principal and most authoritative evidence, that can be given, of the existence of such a custom as shall form a part of the common law. The judgment itself, and all the proceedings previous thereto, are carefully registered and preserved, under the name of records, in publick repositories set apart for that particular purpose; and to them frequent recourse is had, when any critical question arises, in the determination of which former precedents may give light or assistance. And therefore, even so early as the conquest, we find the "praeteritorum memoria eventorum" reckoned up as one of the chief qualifications of those who were held to be "legibus patriae optime instituti[o]." For it is an established rule to abide by former precedents, where the same points come again in litigation; as well to keep the scale of justice even and steady, and not liable to waver with every new judge's opinion; as also because the law in that case being solemnly declared and determined, what before was uncertain, and perhaps indifferent, is now become a permanent rule, which it is not in the breast of any subsequent judge to alter or vary from, according to his private sentiments: he being sworn to determine, not according to his own private judgment, but according to the known laws and customs of the land; not delegated to pronounce a new law, but to maintain and expound the old one. Yet this rule admits of exception, where the former determination is most evidently contrary to reason; much more if it be contrary to the divine law. But even in such cases the subsequent judges do not pretend to make a new law, but to vindicate the old one from misrepresentation. For if it be found that the former decision is manifestly absurd or unjust, it is declared, not that such a sentence was bad law, but that it was not law; that is, that it is not the established custom of the realm, as has been erroneously determined. And hence it is that our lawyers are with justice so copious in their encomiums on the reason of the common law; that they tell us, that the law is the perfection of reason, that it always intends to conform thereto, and that what is not reason is not law. Not that the particular reason of every rule in the law can at this distance of time be always precisely assigned; but it is sufficient that there be nothing in the rule flatly contradictory to reason, and then the law will presume it to be well founded[p]. And it hath been an antient observation in the laws of England, that whenever a standing rule of law, of which the reason perhaps could not be remembered or discerned, hath been wantonly broke in upon by statutes or new resolutions, the wisdom of the rule hath in the end appeared from the inconveniences that have followed the innovation.
