The EU-Mercosur trade deal has been pushed back again after the European Parliament voted in Strasbourg on 21 January 2026 to ask the European Court of Justice for a legal opinion on whether the agreement’s structure complies with the EU treaties. The move, adopted by a narrow margin, adds uncertainty to a pact that EU leaders describe as strategically important for Europe’s trade autonomy at a time of rising tensions with the USA.
Parliament sends the EU-Mercosur deal to the EU court
MEPs backed a resolution requesting the Court’s assessment of the legal basis for two texts signed with Mercosur: a broader partnership agreement and an interim trade agreement. The resolution passed 334–324, with 11 abstentions, reflecting how polarised the issue remains across party lines.
The Court’s opinion is expected to take months and could stretch well beyond a year, depending on how the case is handled. Until the legal review is complete, the Parliament says it will keep examining the text but will not move to a final consent vote.
Why the legal basis matters for ratification
The legal question goes to the heart of how the agreement is meant to be approved and implemented. The Commission has framed the trade part as falling under EU exclusive competence, which would allow faster approval at EU level. Critics argue the deal’s scope makes it a “mixed agreement”, requiring ratification not only by the Parliament but also by national parliaments across the EU.
For opponents, the referral is a way to force clarity before any provisional application. For supporters, it risks opening a long institutional dispute that could stall one of the EU’s largest trade projects at a moment when Brussels is trying to rebuild predictability in its external economic relations.
What the agreement would change, in practical terms
Negotiations with Mercosur — Argentina, Brazil, Paraguay and Uruguay — began more than two decades ago. The deal aims to phase out tariffs on most goods over time, expanding market access for European industry and services while increasing South American agricultural exports.
Supporters in Europe argue that, beyond tariff reductions, the agreement would provide a rules-based framework for investment, standards and dispute settlement, and deepen political cooperation with a region where European influence has been increasingly challenged by other global powers.
Farmers and environmental concerns remain the core fault line
Opposition has been driven in particular by concerns from farming organisations and several member states about competition from lower-cost agricultural imports and about whether production standards match EU requirements.
Environmental groups and some lawmakers also question whether the safeguards are strong enough to prevent the deal from fuelling deforestation and biodiversity loss, especially in the Amazon. The debate has increasingly overlapped with EU rules linking market access to environmental compliance, creating a politically sensitive trade-off between competitiveness and regulation.
Strategic autonomy: why the timing matters for Europe
The Parliament’s decision lands as the EU is actively trying to diversify trade and reduce strategic vulnerabilities. With tariff threats and geopolitical pressure shaping transatlantic relations, EU policymakers have increasingly framed trade agreements as part of Europe’s broader security and competitiveness agenda.
In that context, the EU-Mercosur deal is often presented as a way to widen Europe’s options beyond its traditional partners — including the USA — and to anchor supply chains and standards with a major region of raw materials and growing consumer markets.
What happens next
The next milestone is the Court’s opinion on the agreement’s legal basis. If the Court finds the current structure incompatible with EU treaties, the texts could require revision before entering into force. Even with a positive opinion, the political path remains difficult, with member states and MEPs still divided over agriculture, climate safeguards and enforcement.
For Mercosur governments, the delay revives a familiar pattern: political momentum in Europe is repeatedly followed by long ratification battles. For Brussels, the outcome will be a test of whether the EU can align its strategic autonomy ambitions with internal consensus on trade, climate and competitiveness.
