UK arguments for US operations from its bases blur the line between lawful self-defence and unlawful war on Iran The UK claims any US aircraft flying from bases like Fairford and Diego Garcia can only act in defence of British regional allies. Such a distinction may be unrealistic in a theatre of war.

Important @chathamhouse.org blog by my @lauterpachtcentre.bsky.social colleague Prof Marc Weller. If the original use of force is classed as illegal, any assistance to the aggressor states needs carful legal review and might trigger state responsibility.

Bad news...

While countries participate in an illegal war, the real problems of the world do not get addressed. Shocking.

Excellent Prof @susanbreau.bsky.social and welcome @bsky.app

What is the legality of the US and Israeli attacks on Iran? Legal experts give their views on the lawfulness of the countries’ actions, including the UK’s ‘defensive’ operation

Comparing carbon border adjustment mechanism certificates to EU allowances: price predictability and arbitrage opportunities

🇪🇺 The EU #CBAM's one-week price predictability window allows importers to strategically allocate certificate purchases for unpaid #emissions, generating an average 4.36% cost advantage over EU allowances (EUAs) which increases as EUA prices decline, find Jihun Paek & Brian H. S. Kim 💰️

Madrid bars US from using Spanish bases to attack Iran Spain is an outlier among EU countries in its strong condemnation of the U.S.-Israeli war against Iran.

The U.S. pulled its warplanes from Spanish bases after Madrid prohibited their use against Iran, Spanish Defense Minister Margarita Robles said today.

UK slashes climate aid programmes for developing countries Exclusive: Schemes worth hundreds of millions of pounds to protect biodiversity and oceans likely to be substantially reduced

On the day the UK’s special relations, the USA, withdraws from the UNFCCC, the UK is on the brink of breaching the Paris Agreement. Let’s not forget mitigation, adaptation and finance form a triangle of obligations and are not optional. www.theguardian.com/environment/...

Germany moving closer to participate in France’s nuclear deterrence. Let’s remember that the ICJ has declared most uses of nuclear weapons violations of int’l law. Not sure that Germany could legally participate in their use under the Grundgesetz.

Trump campaign peace promises loom large over Iran war The "anti-war" candidate has bombed seven countries and launched a new regime-change war in Iran.

"No president in the modern era has ordered more military strikes against as many different countries as Donald Trump."

The American Society of International Law has published a statement on the US Use of Force against Iran

We knew this was coming but the withdrawal by Trump from the UNFCCC is still shocking highlighting the overt departure from a global consensus. Can we really trade with a country that directly undermines global climate governance.

I think the usual 'mistakes' such as target misidentification, failure to detect presence of civilians, pre-strike proportionality assessment might all have gone wrong in this case and thus do not constitute excuses. Those who took the strike decision in this case should be held criminally liable.

Refugee status becomes temporary in asylum shake-up Adults and accompanied children claiming asylum will only receive refugee status for 30 months under the changes.

Abysmal, immoral, cruel, small hearted, tiny minded, ineffective, undemocratic, and just generally utterly indecent. What a bitter godforesaken disappointment these people are.

Hidden in the Trade and Sustainable Growth (?) and Development chapter is making the Paris Agreement an essential element in Art 15.7. 3: '... each Party shall remain a party, in good faith, of the Paris Agreement. This obligation shall constitute an essential element of this Agreement.' Good.

Of course it is illegal and a war crime. The 'excuse' of mistakes in war has most recently been debunked by Hathaway and Khan doi.org/10.58112/upl...

Very interesting dynamic alignment provision in Art. 5 of for example this protocol on free movement of persons plus referral mechanism to the Court of Justice in this new EU-Swiss Institutional Agreement. The UK should take note.

Quite a few innovations in this agreement which will become relevant for the UK in the near future. Elegant solution of @eucourtofjustice.bsky.social involvement in my view.
