On the Role of the European Parliament: The Mercosur Treaty

With the European Council, which represents the E.U. states, having passed the Mercosur free-trade treaty by qualified-majority voting, the legislation went on to the European Parliament, which represents E.U. citizens, to vote on final passage before being sent to E.U. President Von der Leyen for her signature. From the standpoint of this standard legislative procedure, it is significant that immediately following the vote in the Council, which is roughly equivalent to the U.S. Senate, efforts were being made to essentially side-step the Parliament, which is equivalent to the U.S. House of Representatives. Von der Leyen’s plan to sign the treaty once it passed in the Council reflects both the disproportionate power of the state governments at the federal level in the E.U. and the fact that the U.S. House is excluded from voting on treaties, whereas the U.S. Senate votes to give its consent to them before the U.S. president ratifies them (or not).  

On 9 January, 2026, the European Council voted by a super majority representing 65% of the E.U.’s population and 55% of its states to approve the Mercosur free-trade treaty with four countries in South America. President Von der Leyen had completed the negotiations on the treaty two years earlier so E.U. companies could “gain access to a market of 280 million consumers . . . where some 30,000 E.U. firms” were already operating.[1] A massive free-trade area with a combined population of 700 million inhabitants would dwarf NAFTA (the North America Free Trade Agreement). It is no wonder that on the heels of the Council’s vote, President Von der Leyen wrote in an official statement, “I greatly look forward to signing this landmark deal . . .”[2] Not so fast. The approval procedure “also requires the consent of the European Parliament.”[3] In the Parliament, a contingent of the Renew party saw an opportunity to scuttle the proposed treaty because of the fears of European farmers, mostly in the state of France, that free trade in agriculture could harm the E.U.’s farmers financially if enough European consumers buy agricultural products from the Mercosur countries rather than domestically.

Admittedly, getting the consent of the Council by even just by qualified-majority voting had been viewed as the challenge. A contingent of the Renew party could presumably be easily outvoted in the Parliament. Nevertheless, the focus on the Council is in line with the inordinate power wielded by the states at the federal level in the European Council and the Council of Ministers. Put another way, being slighted doubtlessly came as no surprise to the representatives in the Parliament. The chamber of the people had typically played second fiddle to the chamber of the states.

Even in the U.S., where the two federal legislative chambers have been viewed as equals since their founding, the U.S. House of Representatives is excluded from the procedure in which treaties proposed by the federal president are sent to the U.S. Senate for advice and to be confirmed (or rejected). If confirmed, the president can either ratify or refuse to do so. Such ratification is required for a treaty to go into effect. The U.S. House of Representatives is excluded.

Resonating with the exclusion of the U.S. House, the E.U. state chairing the Council at the time “used a legal procedure” just after the vote “to enable the provisional implementation of the agreement without a parliamentary vote.”[4] Although the Parliament’s upcoming vote could derail the treaty, the provisional implementation would make it more difficult for representatives to vote against the treaty because it would already be underway. Even if President Von der Leyen would sign the treaty before the Parliament’s vote, the treaty would be rendered invalid, but in setting up a fait accompli, the Commission and the Council were making use of momentum such that voting against the treaty would be more difficult. Furthermore, that the U.S. House is excluded from the legislative consent and ratification of U.S. treaties implicitly implies that maybe the European Parliament, which also represents citizens rather than states, should not be involved in the passage of E.U. treaties with other countries. In federal unions in which governmental sovereignty is divided, regardless of the proportions, the legislative chamber in which the semi-sovereign states are represented can be argued to be more important in international treaties precisely because of the sovereignty still reserved by the states in their political union should have a say, even if by qualified majority voting (in the E.U. Council) or a two-thirds majority (in the U.S. Senate).  Put another way, both of these bars, being higher than a simple majority, reflect the fact that the states in the E.U. and U.S. are semi-sovereign.

In tension with the argument that the E.U. Parliament and the U.S. House should also be included so the respective federal citizens could also have a say, the states might object that a defeat in either of those chambers would nullify what the semi-sovereign state governments have agreed to, and that such sovereignty, together with the limited sovereignty of the respective unions, should not be denied domestically with respect to relations with other countries. The tension here reveals a judgment call, which is of such a magnitude and indeterminacy to be properly determined by popular sovereignty—that which is reserved to the people themselves as an electorate. Moreover, this comparison of the E.U. and U.S. works so well that the equivalency of the two unions, even with the very different proportions of governmental sovereignty delegated by basic law to the federal level, can be easily grasped even by Euroskeptics and anti-federalists.
