ClientEarth takes European Commission to EU’s highest court over illegal transparency rollback

22 September 2025

ClientEarth lawyers have sued the European Commission for illegally changing its transparency rules to prevent the public from accessing crucial documents for their health and the environment.

Lawyers today filed a case before the General Court of the European Union after the European Commission doubled down on its controversial transparency rule changes, despite clear breaches of EU law and binding court rulings. Earlier this year, ClientEarth lawyers asked the EU Commission to  repeal fresh rules  blocking public access to key documents – such as drafts, legal advice, environmental impact assessments, and messages of its officials.   The Commission, refused to do so, leaving no alternative but judicial challenge to uphold democratic accountability and the right to know.

Lawyers argue that the Commission’s stance contradicts EU treaty obligations, the Aarhus Convention and the Aarhus Regulation, as well as multiple rulings by the CJEU, most notably the 2018 ClientEarth v Commission judgment.

Ilze Tralmaka, ClientEarth lawyer, said:

“Despite the damning Pfizergate ruling that exposed secrecy at the highest levels of the EU and the political backlash culminating in a no-confidence vote, the Commission is still choosing a path of secrecy. This is a direct assault on transparency, and we are now taking that fight to the EU’s highest court.”

“Blocking access to documents in the early stages of the legislative process – including legal opinions and internal messages – seriously hinders democratic participation. That’s not just undemocratic, it’s unlawful: EU Treaties guarantee openness, and the Commission cannot simply rewrite the rules in secret.”

“With this legal case, we want to defend citizens’ fundamental right to know – what pesticides end up in our food, what chemicals are hidden in everyday products, and what action is (or isn’t) being taken to protect our health from pollution and climate breakdown.”

The General Court will now review the application for annulment and rule on the legality of the Commission’s decision.
