Supreme Court nominee Brett Kavanaugh has nothing but contempt for international law. But he has shown uncritical deference to executive power, particularly in the so-called war on terror cases.

The two primary sources of international law are treaties and what’s known as “customary international law.” Ratified treaties are part of domestic US law under the supremacy clause of the Constitution, which says treaties “shall be the supreme law of the land.” Furthermore, it has long been established that customary international law, which arises from the consistent and general practice of nations, is part of US law.

Although he professes to interpret the Constitution as written by the founders, Kavanaugh has apparently overlooked the supremacy clause and simply scorns customary international law.

Jordan Paust, international law scholar and professor emeritus at University of Houston Law Center, told Truthout in an email, “The unanimous views of the Founders, Framers, and Supreme Court Justice opinions is that the President and all members of the Executive Branch are bound by international law.” Paust also referenced a 2016 article he wrote in the Houston Journal of International Law documenting this fact.

Kavanaugh, however, erroneously conflates international law with foreign law. The US agrees to the terms of treaties it ratifies. And in most instances, the United States can opt out of a customary international law norm if the US objected while the norm was being developed. Foreign law, on the other hand, is the law of other countries — such as French law, German law, etc.

In the 2016 case of Al Bahlul v. United States, a Guantánamo detainee argued that since “conspiracy” was not an offense under the international laws of war, he should not be tried for conspiracy before a military commission.

Kavanaugh’s concurrence in that case characterized al-Bahlul’s argument as “extraordinary” because “it would incorporate international law into the U.S. Constitution as a judicially enforceable constraint on Congress and the President.”

That would mean, Kavanaugh cynically wrote, that wartime decisions made by the president and Congress to try unlawful enemy combatants before military commissions “would be subject to the dictates of foreign nations and the international community, as embodied in international law.”

He added: “The federal courts are not roving enforcers of international law. And the federal courts are not empowered to smuggle international law into the U.S. Constitution and then wield it as a club against Congress and the President in wartime.”

Kavanaugh and the War on Terror

For 12 years, while serving as a judge on the DC Circuit Court of Appeals, Kavanaugh had the opportunity to rule on several cases stemming from the “war on terror.” In nearly all of them, he demonstrated nothing but disdain for international law and an uncritical deference to executive power.

During the Bush administration, the Supreme Court checked and balanced the executive branch in several war on terror cases. They included Rasul v. Bush (which established that federal courts have jurisdiction to hear Guantánamo detainees’ habeas corpus petitions); Hamdi v. Rumsfeld (which held that a US citizen held as an enemy combatant has due process rights to contest his or her detention); and Hamdan v. Rumsfeld (which concluded that Bush’s military commissions violated the Uniform Code of Military Justice and the Geneva Conventions).

In 2008, the high court ruled in Boumediene v. Bush that Guantánamo detainees held as enemy combatants have the right to file habeas corpus petitions in US federal courts to challenge their detention.

But in the wake of the Boumediene decision, Kavanaugh tried to neuter detainees’ habeas corpus rights in cases that came before him on the Court of Appeals, such as Omar v. McHugh and Uthman v. Obama. University of Texas law professor Stephen Vladeck noted in a 2011 article that since Boumediene was decided, commentators “have accused the D.C. Circuit in general — and some of its judges in particular — of actively subverting [Boumediene] by adopting holdings and reaching results that have both the intent and the effect of vitiating the … decision.”

“Prominent among those judges is Kavanaugh,” Edith Roberts wrote at SCOTUSblog.

In the 2010 case of Al-Bihani v. Obama, Kavanaugh ruled that the Authorization for Use of Military Force (AUMF), under which al-Bihani was held as an enemy combatant, should not be interpreted in light of the international laws of war.

Kavanaugh wrote, “International-law norms that have not been incorporated into domestic U.S. law by the political branches are not judicially enforceable limits on the President’s authority under the AUMF.”

Paust noted in a law review article that Kavanaugh “embraced and basically relied merely on a radical ahistorical and ultimately anti-constitutional minority viewpoint” in that statement.

Kavanaugh “prefers a radical and dangerous view that ‘courts may not interfere with the President’s exercise of war powers based on international-law norms that the political branches have not seen fit to enact into domestic U.S. law,’” Paust wrote.

In fact, Kavanaugh twisted the law to reach what appear to be politically motivated results. Paust opined, “Bias is strikingly evident in [Kavanaugh’s] non-judicious use of the phrase ‘lurking international-law.’”

“This sardonic mischaracterization of law,” according to Paust, “is one that [Kavanaugh’s] former colleagues in the White House (for example, [Alberto] Gonzales, [George W.] Bush, [David] Addington, and [Dick] Cheney) might have appreciated during their infamous era of serial criminality orchestrated in the White House.” But, Paust added, “it is decidedly out of place in an impartial appellate chamber within the judicial system of the United States.”

Another example of Kavanaugh’s disrespect for international law and fondness for executive power is the 2009 case of Kiyemba v. Obama. Seventeen Uighur men found to be unlawfully detained at Guantánamo feared being returned to China in violation of the United Nations Convention Against Torture and a federal statute, given the likelihood that they would face torture upon their return. Kavanaugh took the position that courts must defer to the president’s determination of whether there is a likelihood of torture upon return. Most of the Uighurs were ultimately relocated to other countries, but many remain in detention.

A Dangerous Presumption

Kavanaugh’s deference to the president goes even further. In a 2014 law review article, he wrote that the take care clause of the Constitution requires the president to enforce the law, “at least unless the President deems the law unconstitutional, in which event the President can decline to follow the statute until a final court order says otherwise.” Kavanaugh would create a dangerous presumption in favor of a president who refuses to follow the law.

If confirmed to the Supreme Court, Kavanaugh will almost certainly defer to the president’s wartime decisions during the perpetual war on terror. He will likely extend that deference to Donald Trump’s immigration policies under the guise of “national security.” And Kavanaugh’s frightening theory will encourage the president to disobey any law he deems unconstitutional, including customary and treaty-based international law.
