What's happened so far?

In turn, in mid-March this year. The Sejm adopted a resolution in which it asked the government to submit a complaint to the CJEU on behalf of Poland, regardless of the complaint filed by the European Parliament. The Sejm indicated that Member States may bring a complaint for the invalidation of an act of the European Union, alleging lack of competence, violation of essential procedural requirements, violation of the Treaties or any legal rule related to its application, or abuse of power.

Earlier, in February, the President of the European Commission, Ursula von der Leyen, announced that the EC would begin the provisional application of the trade agreement. Under the EU treaties, the agreement can only be fully concluded once the European Parliament has given its consent. However, the trade agreement will be provisionally applied from May 1 this year. with all countries that complete their ratification procedures and have notified the Community thereof before the end of March.

This means that from May it will be possible to import products such as beef, poultry, dairy products, sugar and ethanol into the EU at more favorable customs rates for South American producers. However, such a reduction will only apply to the quantities of a given product specified in the contract. In return, Mercosur countries will reduce tariffs on European industrial goods, including cars, which are in many cases prohibitive.

The provisions of the agreement in the part relating only to trade will apply, as this is the competence of the European Commission. In practice, this means the immediate abolition of customs duties and trade barriers. Other issues will remain pending until full ratification, such as investment protection and public procurement. In this case, ratification by the European Parliament and the Member States will be needed.

From May 1 this year the so-called a protective clause to the agreement, which is intended to respond to the concerns of farmers who anticipate an excessive inflow of Mercosur products to the EU. It will be activated if the prices of a given product in the EU drop by 5% as a result of imports from Mercosur. It will then be possible to increase customs duties on a given product or introduce an import ban into the EU. (PAP)
