Los bombardeos de EEUU contra Irán ocurren a menos de dos meses del ataque militar a Venezuela y tras otras amenazas de EEUU de usar la fuerza. Comparto aquí mi entrevista en Internacional con Ñ sobre EEUU, Venezuela y la llamada ‘muerte’ del derecho internacional. open.spotify.com/episode/3JRg...

Ahora disponible en español. Este artículo, escrito junto a @aratojulian.bsky.social, analiza el ataque de Estados Unidos contra Venezuela y sus consecuencias a la luz del derecho internacional. lacritica.ar/post/ataque-...

NB Superb analysis by @justinauriburu.bsky.social @aratojulian.bsky.social: 'The attack on Panama, like this weekend’s attack on Venezuela, was simply illegal. In fact, several of these historical arguments have since become textbook examples of impermissible justifications under the jus ad bellum.'

Justina Uriburu @justinauriburu.bsky.social and Julian Arato @aratojulian.bsky.social: "Trump’s Illegal Attack on Venezuela and Its Consequences" The attack "was plainly illegal" - "a flagrant and grave violation" of Article 2(4) of the UN Charter, "and a severe breach of US law". 1/12

US attacks on Venezuela and the abduction of Nicolás Maduro raise profound legal and geopolitical concerns, with implications well beyond Venezuela itself. In a new post co-authored with Julian Arato, we examine the attack and its broader consequences under international law.

VALE LER: O ataque ilegal de Trump à Venezuela e suas consequências, por @justinauriburu.bsky.social e @aratojulian.bsky.social jnascim.info/x1Fsvk

My latest together with @justinauriburu.bsky.social No love lost for Maduro, and no apologies made for his regime. But the attack on Venezuela was plainly illegal. States can either say so clearly, or parse their way into a law of boundless exceptions and self-judgment.

What does de-dollarisation mean in practice? How does it relate to global law and governance? My article 'Dollar Dominance, De-Dollarization, and International Law' is now out in JIEL. I present dollar dominance and de-dollarisation as competing legal institutions. academic.oup.com/jiel/advance...

This week, despite Venezuela's 2012 denunciation of the American Convention, the IACtHR held that Venezuela remains bound. Why? Because Guaidó re-ratified the Convention, retroactive to 2013, in 2019. The catch? Maduro was incumbent before and after Guaidó, and, arguably, during Guaidó. Read👇

Excellent post by @aratojulian.bsky.social & Justina Uriburu - www.ejiltalk.org/treaty-and-c...

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 👇

There is, undoubtedly, much to say about the ICJ’s landmark advisory opinion on Obligations of States in respect of Climate Change. In this post, Julian and I begin by unpacking the Court’s treatment of the sources of international law governing climate change and how those sources interact.

After 17 years of serving as EJIL Editor in Chief, he is now stepping down. In his words: ‘for real’. It is an occasion for an in-person conversation: many people know ‘Weiler’ by name or by initials ‘JHHW’; fewer people know him in person. Who is Joseph Halevi Horowitz Weiler?
