Germany's highest court hears Green challenge to minister's unilateral repeal of nutrient rule
The Federal Constitutional Court in Karlsruhe is hearing a complaint from the Green party over Agriculture Minister Alois Rainer's decision to abolish the Stoffstrombilanzverordnung without involving the Bundestag. The Greens argue the move violates parliamentary rights, calling it 'Trump-style politics.'
Background
The Stoffstrombilanzverordnung, introduced in 2018 under the Fertilizer Act, required farmers to document all nutrient inputs and outputs on their holdings. Designed to curb groundwater pollution from nitrates and phosphorus, the regulation obliged detailed records of fertiliser, feed, and harvest flows. Many farmers criticised it as bureaucratic, and in July 2025 Agriculture Minister Alois Rainer (CSU) abolished the ordinance without parliamentary consultation. The repeal was justified as saving about €18 million in annual red tape, with the ministry insisting groundwater protection would not suffer.
The Green party's complaint
The Greens filed a constitutional complaint, arguing that the Fertilizer Act explicitly requires Bundestag involvement when such regulations are amended or revoked. They claim the minister's solo act bypassed parliament, violating its constitutionally guaranteed rights. The faction likened the approach to 'Trump-style politics.'
This is Trump-style politics — without regard for democratic institutions and the principle of separation of powers.
The government's defence
A spokesperson for the Agriculture Ministry stated that the Interior and Justice Ministries were consulted in advance and both confirmed no need for Bundestag or Bundesrat approval. The repeal had majority support among state governments and had been agreed in the coalition agreement of the previous black-red government.
Both constitutional departments confirmed that from their perspective the repeal of the Stoffstrombilanzverordnung requires neither the consent of the Bundesrat nor the participation of the Bundestag.
What's at stake
The case (Az. 2 BvE 15/25) goes beyond a single regulation. Administrative law expert Wilhelm Achelpöhler notes an observable shift of decision-making power from parliament to government, citing parallel debates on conscription. The court's eventual ruling will clarify the limits of ministerial authority and the conditions under which the legislature must be consulted.
- Stoffstrombilanzverordnung comes into force, requiring farmers to document nutrient inputs and outputs.
- Agriculture Minister Alois Rainer abolishes the regulation without parliamentary involvement.
- Federal Constitutional Court hears the Green party's complaint.
What happens next
The court heard arguments on Tuesday and will deliberate; a written judgment is expected in several months. The decision will set a precedent for similar separation-of-powers disputes.
