''It is now the settled doctrine of this Court that the Due Process Clause embodies a system of rights based on moral principles so deeply imbedded in the traditions and feelings of our people as to be deemed fundamental to a civilized society as conceived by our whole history. Due Process is that which comports with the deepest notions of what is fair and right and just.'' 1 The content of due process is ''a historical product'' 2 that traces all the way back to chapter 39 of Magna Carta, in which King John promised that ''[n]o free man shall be taken or imprisoned or disseized or exiled or in any way destroyed, nor will we go upon him nor send upon him, except by the lawful judgment of his peers or by the law of the land.'' 3 The phrase ''due process of law'' first appeared in a statutory rendition of this chapter in 1354. ''No man of what state or condition he be, shall be put out of his lands or tenements nor taken, nor disinherited, nor put to death, without he be brought to answer by due process of law.'' 4 Though Magna Carta was in essence the result of a struggle over interest between the King and his barons, 5 this particular clause over time transcended any such limitation of scope, and throughout the fourteenth century par liamentary interpretation expanded far beyond the intention of any of its drafters. 6 The understanding which the founders of the American constitutional system, and those who wrote the due process clauses, brought to the subject they derived from Coke, who in his Second Institutes expounded the proposition that the term ''by law of the land'' was equivalent to ''due process of law,'' which he in turn defined as ''by due process of the common law,'' that is, ''by the indictment or presentment of good and lawful men . . . or by writ original of the Common Law.'' 7 The significance of both terms was procedural, but there was in Coke's writings on chapter 29 a rudimentary concept of substantive restrictions, which did not develop in England because of parliamentary supremacy, but which was to flower in the United States.
The term ''law of the land'' was early the preferred expression in colonial charters and declarations of rights, which gave way to the term ''due process of law,'' although some state constitutions continued to employ both terms. Whichever phraseology was used, the expression seems generally to have occurred in close association with precise safeguards of accused persons, but, as is true of the Fifth Amendment here under consideration, the provision also suggests some limitations on substance because of its association with the guarantee of just compensation upon the taking of private property for public use. 8
Scope of the Guaranty .--Standing by itself, the phrase ''due process'' would seem to refer solely and simply to procedure, to process in court, and therefore to be so limited that ''due process of law'' would be what the legislative branch enacted it to be. But that is not the interpretation which has been placed on the term. ''It is manifest that it was not left to the legislative power to enact any process which might be devised. The article is a restraint on the legislative as well as on the executive and judicial powers of the government, and cannot be so construed as to leave congress free to make any process 'due process of law' by its mere will.'' 9 All persons within the territory of the United States are entitled to its protection, including corporations, 10 aliens, 11 and presumptively citizens seeking readmission to the United States, 12 but States as such are not so entitled. 13 It is effective in the District of Columbia 14 and in territories which are part of the United States, 15 but it does not apply of its own force to unincorporated territories. 16 Nor does it reach enemy alien belligerents tried by military tribunals outside the territorial jurisdiction of the United States. 17
Early in our judicial history, a number of jurists attempted to formulate a theory of natural rights--natural justice, which would limit the power of government, especially with regard to the property rights of persons. 18 State courts were the arenas in which this struggle was carried out prior to the Civil War. Opposing the ''vested rights'' theory of protection of property were jurists who argued first, that the written constitution was the supreme law of the State and that judicial review could look only to that document in scrutinizing legislation and not to the ''unwritten law'' of ''natural rights,'' and second, that the ''police power'' of government enabled legislatures to regulate the use and holding of property in the public interest, subject only to the specific prohibitions of the written constitution. The ''vested rights'' jurists thus found in the ''law of the land'' and the ''due process'' clauses of the state constitutions a restriction upon the substantive content of legislation, which prohibited, regardless of the matter of procedure, a certain kind or degree of exertion of legislative power altogether. 19 Thus, Chief Justice Taney was not innovating when in his opinion in the Dred Scott case he pronounced, without elaboration, that one of the reasons the Missouri Compromise was unconstitutional was that an act of Congress which deprived ''a citizen of his liberty or property merely because he came himself or brought his property into a particular territory of the United States, and who had committed no offence against the laws, could hardly be dignified with the name of due process of law.'' 20 Following the War, with the ratification of the Fourteenth Amendment's due process clause, substantive due process interpretations were urged on the Supreme Court with regard to state legislation; first resisted, the arguments came in time to be accepted, and they imposed upon both federal and state legislation a firm judicial hand which was not to be removed until the crisis of the 1930's, and which today in non-economic legislation continues to be reasserted.
''It may prevent confusion, and relieve from repetition, if we point out that some of our cases arose under the provisions of the Fifth and others under those of the Fourteenth Amendment to the Constitution of the United States. While the language of those Amendments is the same, yet as they were engrafted upon the Constitution at different times and in widely different circumstances of our national life, it may be that questions may arise in which different constructions and applications of their provisions may be proper.'' 21 The most obvious difference between the two due process clauses is that the Fifth Amendment clause as it binds the Federal Government coexists with a number of other express provisions in the Bill of Rights guaranteeing fair procedure and non-arbitrary action, such as jury trials, grand jury indictments, and nonexcessive bail and fines, as well as just compensation, whereas the Fourteenth Amendment clause as it binds the States has been held to contain implicitly not only the standards of fairness and justness found within the Fifth Amendment's clause but also to contain many guarantees that are expressly set out in the Bill of Rights. In that sense, the two clauses are not the same thing, but insofar as they do impose such implicit requirements of fair trials, fair hearings, and the like, which exist separately from, though they are informed with, express constitutional guarantees, the interpretation of the two clauses is substantially if not wholly the same. Save for areas in which the particularly national character of the Federal Government requires separate treatment, discussion of the meaning of due process is largely reserved for the section on the Fourteenth Amendment. Finally, it should be noted that some Fourteenth Amendment interpretations have been carried back to broaden interpretations of the Fifth Amendment's due process clause, such as, e.g., the development of equal protection standards as an aspect of Fifth Amendment due process.

[Footnote 3] Text and commentary on this chapter may be found in W. McKechnie, Magna Carta--A Commentary on the Great Charter of King John 375-95 (Glasgow, 2d rev. ed. 1914). The chapter became chapter 29 in the Third Reissue of Henry III in 1225. Id. at 504, and see 139-59. As expanded, it read: ''No free man shall be taken or imprisoned or deprived of his freehold or his liberties or free customs, or outlawed or exiled, or in any manner destroyed, nor shall we come upon him or send against him, except by a legal judgment of his peers or by the law of the land.'' See also J. Holt, Magna Carta 226-29 (Cambridge: 1965). The 1225 reissue also added to chapter 29 the language of chapter 40 of the original text: ''To no one will we sell, to no one will we deny or delay right or justice.'' This 1225 reissue became the standard text thereafter.
