Reports of another horrific use of chemical weapons against civilians in Syria seems to have affected President Trump. In comments today, President Trump said the chemical attacks against civilians "crossed a lot of lines for me" and changed the way he views Syria and leader Bashar al-Assad. Although it is always hard to interpret the President's comments, he did cite his "flexibility" to change...

Today, the U.S. Supreme Court agreed to hear the case of Jesner v. Arab Bank in order to resolve a single issue: “[w]hether the Alien Tort Statute, 28 U.S.C. § 1350, categorically forecloses corporate liability.” This post will briefly review the case and offer a quick assessment of the ATS corporate liability issue.  Longtime readers will not be surprised to...

There are lots of panels and conferences being held around the U.S. (and maybe outside the U.S.) on the new Trump Administration's policies and their impact on international law. I would like to recommend our readers view some or all of the video from this half-day conference recently hosted in Washington D.C. by the Federalist Society and the American Branch of...

The legal battle over President Trump’s recent executive order has cast a spotlight on the president’s broad and potentially abusive powers over U.S. immigration laws.  But it is worth remembering that this power can be used in many different ways, including in ways that the President’s critics would support.  This past December, Congress delegated to the president broad discretionary powers...

Because I am on sabbatical this semester, I have been lying low during these first few (very busy!) weeks of the Trump administration.  But I have noticed that the sheer volume of Trump administration actions, and reactions to its actions, is confusing both its supporters and its critics.  While Trump has already taken actions that are worthy of severe criticism...

As we all continue to digest the stunning election results from last week, I continue to focus on ways in which a President Trump could use his substantial powers over foreign affairs in unique and unprecedented ways.  Withdrawing from trade agreements could be a major theme of his administration.  Somewhat less noticed is the possibility that a President Trump fulfills...

Following Donald Trump’s stunning election victory, ballot measures are already being proposed in California and Oregon to secede from the United States.  Ordinarily, one can just chuckle at these measures as the actions of a radical fringe, but it would be hard to overestimate the depth of anger and opposition to a President Trump in states like California, where he lost...

As regular readers of this blog probably guessed, I did not support Donald Trump for President (I didn’t support Hillary Clinton either, but that’s another story). I did, however, take the possibility of his election seriously and published a couple of posts (see this one here) analyzing the legal issues raised by his campaign promises to withdraw from existing U.S....

Early in my international law education here in the U.S, I learned that dualism was an unfortunate concept that led to the U.S. violating international law obligations by failing to enforce those obligations (usually treaties) domestically.  But today's blockbuster decision from a UK court in Miller v. Secretary of State on Brexit should remind us that dualism can also work to...

As we face the first U.S. presidential debate tonight (on my home campus of Hofstra University!),  the possibility of a President Trump seems more and more real.  Although U.S. election analysts all make Hillary Clinton the favorite, most of them continue to give Trump a very realistic chance of winning on November 8.  I am not a Trump supporter, but I think...

After months (or even years) of threats, Ukraine finally filed an arbitration claim against Russia under Annex VII of the UN Convention of the Law of the Sea.  According to this statement from the Ukrainian Ministry of Foreign of Affairs, the claim will focus on Russia's actions in the maritime zones bordering Crimea. Since the Russian Federation’s illegal acts of aggression in...
