In the rousing conclusion of the op-ed, Post and Minow invoke the rule of law, around which they encourage the American people to rally. Despite according it the highest value, the Deans do not define the rule of law, although they appear to equate it with adherence to a legal order in which "official, publicly justified sanctions [are substituted] for animosity and enmity". It is also cast as the opposite of tyranny, a state of affairs in which a "so-called president" can presumably pursue vendettas without restriction.
Despite vague allusions to a whole range of American values, the deans' vision of the rule of law is surprisingly thin; it could just as easily be called legality, or legalism. It seems strange, however, to say that whatever a judge would opine should be above criticism merely because of their status as the guardians of the laws, as if the content of the laws does not matter. However, this empty formalism and "the legitimacy and authority of judges" may be all that the American legal profession has to defend.
Trump purported to suspend the entry of hundreds of thousands of immigrants and refugees. His full-throated cry for unfettered control received the response from the judiciary (and now the professioriate) that one would expect. However, President Obama made the same argument repeatedly, although more quietly and successfully. In Kiyemba v. Obama, twenty-two Uighur detainees--who had never been labelled enemy combatants--argued that they should be released from Guantanamo Bay. Despite being granted habeas corpus, the government's lawyers argued that no court had the power to admit them into the United States (as this belongs to the executive exclusively), even if this was done to bring the detainees into the presence of the court adjudicating their petitions.
When the Supreme Court refused to uphold the grant of the writ, it struck a dagger into the heart of the rule of law. It allowed the government to prevent courts from giving relief to those that the government detained illegally, even while it admitted they were factually innocent. The Deans of Harvard and Yale penned no op-eds about Kiyemba, just as they held their silence when a court upheld the targeted killing of an American citizen, wherein it concluded that while "[T]he plaintiff asks this court to . . . assess the merits of the President’s (alleged) decision to launch an attack on a foreign target . . . [that] happens to be a U.S. citizen, the same reasons against judicial resolution of the plaintiffs’ claims . . . apply with equal force."
For fifteen years, American courts used smooth language to justify handing unreviewable powers to the executive with no complaints from the nation's law deans. Now that Trump is asserting that he can use these powers as he pleases, they label his statements as a danger to the rule of law. Unfortunately, the op-ed presents Trump with ample opportunities for a counter-attack. The deans fail to understand that Trump attacks judicial decisions as politically biased, and driven by the political affiliations of the justices. In condemning Trump's order banning refugees from the country but not Obama's order barring Guantanamo detainees seeking justice, the Deans exemplify the legal profession's tolerance for executive power during the Obama administration. Trump's appeal is closely related to his disdain for elite hypocrisy: the deans should have been more careful not to provide him with an opportunity to deploy one of his favourite rhetorical weapons.
There are other indications that the theoretical basis for Minow's attack on Trump is not as solid as it should be, leaving them exposed to counter-attacks. They invoke the "political philosophy" of the Nazi jurist Carl Schmitt as a forerunner of the President's belligerent approach, while failing to note that within their own law schools numerous professors have--for decades--held up Schmitt's work as a persuasive rebuttal of classical arguments about the rule of law and the reality of a division between law and politics. It would bring a cynical smile to the face of anyone who studied jurisprudence in an elite American law school to see Schmitt being deployed as a bogeyman, as his work was routinely cited with approval by numerous leading legal scholars.
If the president's party (or ideology) defines his critics' stance on executive power and the parameters of the rule of law, then these Deans are right to throw their weight against criticism of the "authority and legitimacy of the judiciary", as its ethos serves as the last remaining justification for a role for the legal profession in the American state. However, one might hope that within the American legal academy there are still scholars who can demonstrate that one's defence of the constitutional order can be principled and consistent.
