Legal process The legal process school was first given definition by Hart's manuscript of the same name, co-authored with Albert M. Sacks. Originally planned for publication by Foundation Press in 1956, the manuscript was organized into seven chapters, with 55 "problems" which guided the student through Hart and Sacks proposed approach to important American law cases. Despite being widely circulated in manuscript form, which itself went through four major editions, the Legal Process was not published in book form by Foundation Press until 1994. The manuscript editions, however, were widely circulated and very influential among the professoriate, many of whom used it as the foundation for courses at Harvard Law and other institutions. An exploration of law made both by courts and outside the courtroom, scholars have identified three key themes from the work itself: (1) Institutional competence, (2) Statutory interpretation, and (3) principled decisionmaking.
Institutional competence "This perspective stresses that Hart and Sacks 'believed that it was possible to distinguish legitimate and illegitimate exercises of official power while simultaneously transcending the centuries-old debate between ... the 'is' and the 'ought'.' The Legal Process demonstrated that lawyers did not have to engage in substantive moral or political reasoning, since 'there could be a kind of natural, functional correlation between different kinds of disputes and different kinds of institutions, so that the categories of dispute could be matched up with the kinds of institutional procedures corresponding to them.' Thus, by adopting the value pluralism of pragmatists like
John Dewey, legal process was able to argue - contra the realists - that the analysis of legal validity is not reducible to political ideology."
Statutory interpretation Hart and Sacks argued for a shift away from the application of substantive, precedential rules, critiqued by the realists, in favor of application of rules of precedential process. "Granting that substantive fairness is a matter of ideology, the doctrinal approach holds that fairness will result, regardless or even in spite of the judges' biases, if methods of judging which all concede to be fair are followed scrupulously." Hart and Sacks "believed that judges should use various tools of construction -- including the overall policy evinced by the statutory text, the legislative history, and public knowledge . . . -- to determine what 'purpose ought to be attributed to the statute' and to interpret the words 'to carry out the purpose as best it can.'" These procedural rules become a way to distinguish between adjudication and ad hoc legislation, the first of which is the role of the courts. In their famous phrase, judges "should assume, unless the contrary unmistakably appears, that the legislature was made up of reasonable persons pursuing reasonable purposes reasonably."
Principled decision-making One of the key tenets of Hart's thought was "principled decisionmaking," or the idea that "decisions [must] be based on premises of general applicability, otherwise they would be ad hoc or 'legislative'" and that the adjudication must be neutral, "thereby claiming the allegiance of litigants through a tacit arrangement of reciprocity...." Heavily influenced by Justice Benjamin Cardozo's approach to adjudication, "principled" decisionmaking thus transcends the immediate outcome of the case at the bar, and through appeal to neutral adjudication principles, "thereby claim[s] the allegiance of litigants through a tacit arrangement of reciprocity." in Judge
Learned Hand's criticism of the activist Warren Court, and which remains an important and debated concept in modern jurisprudence. Other scholars have tied Hart's requirement of principled reasoning to the wider "postwar liberal project associated with
Robert Dahl and
John Rawls" as well as with the work of
John Hart Ely and
Ronald Dworkin.
Hart's dialogue In 1953, Hart addressed the question of Congress's power over federal jurisdiction in his very influential article, "The Power of Congress to Limit the Jurisdiction of the Federal Courts." Included in his
Federal Courts, which was published later the same year, this article has come to be known as "Hart's Dialogue" and argues for the proposition ("Hart's postulate") that one always has access to a constitutional court to rule on: 1) claims of entitlement to/ sufficiency of judicial process; and 2) claims that rights are violated and not vindicated. "the most influential casebook in Constitutional law" and also "the book most frequently cited by the Supreme Court both generally and in constitutional opinions."
Federal Courts "define[d] what has come to be one of the most important schools of legal thought in late twentieth-century America, typically described as 'the
legal process school.'" In broad brushstrokes, the school "focuses primary attention on who is, or ought, to make a given legal decision, and how that decision is, or ought to be made.... The question what is or ought to be the substantive law governing citizen behavior in a given area is no longer the sole, or even the dominant, object of legal analysis. Rather, the legal process analysis illuminates how substantive norms governing primary conduct shape, and are in turn shaped by, organizational structure and procedural rules." Hart and Wechsler's initial response was that, if there may be widespread disagreement on what the substantive law is, or ought to be, in a given field, there may at least be agreement as to where institutionally those decisions should be made, and under what conditions or set of rules (such as jurisdiction, procedure, etc.). The role of the courts, particularly with respect to the Constitution, "is essentially a common law function, arising from the court's common law process respecting litigants." Thus, "[b]y paying strict attention to second-order rules allocating power between federal courts and other institutions, the legal process theorists sought to specify with precision the boundaries and purposes of federal judicial power. Once these boundaries were specified, federal judicial decisionmaking could be both legitimated and restrained." Among innovations introduced by
The Federal Courts was the idea of a federal "protective jurisdiction," or the idea that Congress could extend federal jurisdiction to cases implicating a federal interest, "even in the absence of both diversity jurisdiction and a claim based on federal law." ==Influence==
