The most striking feature of the Supreme Court's decision in United States v. Curtiss-Wright Export Corp. is its language asserting an independent and exclusive executive foreign affairs power. As “the sole organ of the federal government in the field of foreign relations,” the Court declared, the executive holds “very delicate, plenary and exclusive power” that “does not require as a basis for its exercise an act of Congress.” From the day the case was decided, it has stood as a preeminent authority for those who would magnify the constitutional role of the president by proclaiming the independent and unchecked nature of the executive's foreign affairs power.

National self-determination was one of the most important and controversial concepts in twentieth century international relations and law. The principle has had a remarkable history, from Woodrow Wilson's assertion that the peoples of Eastern Europe ought to form their own national states in place of ruined multiethnic and multilinguistic empires after the First World War; to decolonization after the Second World War, when populations worldwide invoked a right to throw off the yoke of imperialism; to the breakup of and war in the former Yugoslavia at century's end in precisely the same area in which a nation's self-determination was first intended to be a panacea for the region's diverse peoples. And yet, national self-determination, if not always called that, has a much longer lineage. Some note its earliest appearance in 1581, when the Dutch claimed independence from Hapsburg Spain. However, it was not until the French Revolution when, as Alfred Cobban remarks, “the nation state ceased to be a simple historical fact and became the subject of a theory,” that a people's right to determine its destiny in international as in domestic affairs was first articulated and applied. The clearest instance of this articulation and application during the Revolution was the union of Avignon and France.

The enactment of the Statute of Westminster in 1931 represents one of the most significant events in the history of the British Empire. The very name of this historic piece of legislation, with its medieval antecedents, epitomizes a sense of enduring grandeur and dignity. The Statute of Westminster recognized significant advances in the evolution of the self-governing Dominions into fully sovereign states. The term “Dominion” was initially adopted in relation to Canada, but was extended in 1907 to refer to all self-governing colonies of white settlement that had been evolving in the direction of greater autonomy since the middle of the nineteenth century. By the early 1930s, the Dominions included Canada, Australia, New Zealand, South Africa, Newfoundland, and the Irish Free State.

MH, a domestic cook who was 26 years of age, was charged with murdering her newborn infant in September 1931. MH had been “seeing a boy” who, she stated, “took advantage” of her on one occasion, procuring her consent to sexual intercourse by a promise of marriage. She claimed that she only realized she was pregnant during the later months of her pregnancy, but did not inform the father of her child. Her employer, suspecting that MH was pregnant, enquired on several occasions whether she could do anything to help, but MH did not admit her “condition.” Although her employer was aware that MH had no family or home to go to, she gave MH notice to quit her job. A couple of weeks later, MH gave birth in her bedroom at her employer's home; she did not call out for assistance or disturb the girl with whom she shared the bedroom. MH admitted in her statement that the baby cried after birth and that she “tied a white dress belt … around its neck to kill it,” adding: “I tied it [the belt] tight. I killed the child and I know I killed it.” Afterwards, MH put the body in a suitcase, cleaned up the bloodstains, and returned to work. The suspicions of her employer eventually lead to the discovery of the dead infant. The postmortem examination showed that the infant had been born alive, but had received no attention at birth; death was the result of strangulation. MH was acquitted of murder at the Central Criminal Court.

It is frequently claimed that adjudication before a court of law and historical adjudication are two entirely different tasks. The methods and techniques employed by judges and historians contrast sharply. The judge faces many constraints, in terms of choice of subject matter, the arguments to be considered, the evidence to be evaluated, the procedural steps to be followed, the substantive rules to be applied, and the time available to reach a decision; historians, by contrast, are relatively free to choose their field of research, manage their own time, gather the evidence, evaluate it, decide when findings are ready to be published, and reexamine them.
