From Monet paintings to courtrooms, Germany's climate activists are redefining protest. But is civil disobedience crossing legal lines—or forcing change?

Germany's climate activism divide pits ex-spy chief against potato-throwing protester

The debate over climate activism in Germany remains unresolved, with differing views on protest tactics and legal boundaries. Former intelligence chief Thomas Haldenwang and activist Mirjam Herrmann represent opposing perspectives on the issue. Recent court cases and past statements highlight ongoing tensions between authorities and groups like Letzte Generation (Last Generation).

Thomas Haldenwang, a jurist, led Germany's domestic intelligence agency, the Bundesamt für Verfassungsschutz, from 2018 until his resignation in 2024. During his tenure, he refused to label Letzte Generation as an extremist organisation. While critical of their methods—particularly protests that disrupted uninvolved bystanders—he argued that legal avenues for climate activism had not yet been fully explored. His stance emphasised moderation, urging activists to operate within the law.

Mirjam Herrmann, a prominent member of Letzte Generation, gained attention in October 2022 after throwing mashed potatoes at a Claude Monet painting in Potsdam's Museum Barberini. Now, she faces a lengthy trial, with weekly hearings scheduled over the coming months. Prosecutors accuse her of forming a criminal organisation, a charge she will contest in court later this year.

Herrmann has repeatedly argued that not all activists in Germany face equal treatment. She claims some groups encounter harsher police crackdowns and systemic barriers, depending on who is protesting. Meanwhile, no changes in public perception or legal classification of Letzte Generation have emerged since Haldenwang's departure in 2024. Current records from 2026 show no updates on the group's status.

The legal battle involving Herrmann will test Germany's approach to climate protests and freedom of assembly. Haldenwang's past comments underscore the fine line between activism and legality. For now, the status of Letzte Generation remains unchanged, leaving the debate over protest tactics unresolved.
