Quote: “The opinion’s true legacy may lie not only in its legal conclusions, but in its power to influence political will, guide national courts, and support vulnerable communities seeking justice.”

Julian Arato @aratojulian.bsky.social · Jul 24

An inspiring opinion for our challenging times. Law can’t do it all nor can courts. But they can do more than many give them credit for.

Here the ICJ takes the development of climate change law fully seriously. @justinauriburu.bsky.social & I get into the central prob of sources of law below 👇

Some very important conclusions on attribution, plural responsibility, plural invocation, etc., all designed to avoid shrugging off responsibility through gaming the rules of state responsibility (ARSIWA)

Julian Arato @aratojulian.bsky.social · Jul 23

I agree. V important.

Julian Arato @aratojulian.bsky.social · Jul 23

Sure did. There was a “not necessarily” wiggle room in there but, yes.

Julian Arato @aratojulian.bsky.social · Jul 23

And CT seems to have said lack of cooperation re the treaties raises demand on states to demonstrate they are complying with customary IL

Thus custom and treaty exist in a dynamic relationship in operationalization - not just interpretation.

An imp litigation tool, even in national ct litigation

Julian Arato @aratojulian.bsky.social · Jul 23

“At the present stage compliance in full and in good faith with the climate change treaties by a court suggests compliance with the customary duties to prevent substantial environmental harm and to cooperate.”

This does not mean, however, that compliance with one will satisfy the other.

Julian Arato @aratojulian.bsky.social · Jul 23

Court making the further important point that the climate change treaties and customary IL should be understood as informing each other.

ICJ is doing this in a way as to make both sources more robust, not to read them both down as would also be possible if the court were less serious about this.

Julian Arato @aratojulian.bsky.social · Jul 23

Also imp to expound on the customary IL duty to cooperate in this context

1

Julian Arato @aratojulian.bsky.social · Jul 23

Good and strong explanation and deployment of customary international law due diligence obligation (part of duty to prevent) to avoid diffuse causation problems that always plague the legal responsibility for climate change.

And good for the ICJ to flesh out obligation of due diligence pretty far

Annual reminder to younger law faculty that the importance of journal placement (ranking) is VERY exaggerated, with respect to most things that matter to your professional satisfaction and trajectory.

Write something good and let it ride; don't write for placement.

The case covers a lot of ground, often in ways that might surprise international economic lawyers (especially re investment treaty standards).

The full Agora is worth a read.

It was fun writing a piece with with Fernando Lusa Bordin for this Agora on the ICJ’s Certain Iranian Assets judgment.

We focus on the court’s assessment of the juridical status of companies in international law—under the treaty and (implicitly) in general IL.

It's publication day! It is my fervent hope to see Western legal systems recognize the unassailable reality that human survival & flourishing is inseperable from the well-being of our planet. The ecocide conversation is one place to start: journals.law.harvard.edu/hrj/wp-conte...
