The Constitution of the United States twice declares that a person shall not be “deprived of life, liberty, or property, without due process of law” — either by the federal government (Fifth Amendment) or by state governments (Fourteenth Amendment). According to Alexander Hamilton, “the words ‘due process’ have a precise technical import, and are only applicable to the process and proceedings of the courts of justice; they can never be referred to an act of the legislature.”368 At the very least, the two fateful words already had a long history in Anglo-Saxon law as of the time they were first placed in the American Bill of Rights in 1791.369 An even longer history of arbitrary power — of lands and even lives confiscated by royal or imperial decrees, and of heads cut off by peremptory order — lend momentous importance to the requirement that only prearranged legal procedures may deal with the fundamental rights of individuals. Centuries of struggle and bloodshed lay behind those two words.

There was an historically brief respite from the “substantive due process” interpretation after the Supreme Court in 1873 refused to consider the substantive merits of a state-created slaughterhouse monopoly in Louisiana, on grounds that to rule on the substantive merits “would constitute this court a perpetual censor upon all legislation of the states.”371 It continued to resist the efforts of those unsuccessful elsewhere to use the Supreme Court to review the substantive justice of lower court decisions or “the merits of the legislation on which such a decision may be founded.”372 However, less than two decades later, a new Supreme Court declared in 1887 that it would look beyond “mere pretenses” to “the substance of things.”373 By the turn of the century, the era of “substantive due process” was launched — in which the Supreme Court repeatedly invalidated as unconstitutional laws regulating businesses or working conditions. The “substantive due process” era lasted longer than the Warren Court era. It was, of course, lamented in retrospect by those who supported the Warren Court’s activism.
