European Law Firm in Warsaw — When EU Law Wins the Case

"European law" sounds abstract — until an EU directive decides whether you get a long-term resident card, whether your qualifications are recognised, or whether ZUS issues an A1 certificate. A European law firm is not a separate breed of lawyers, but a firm able to reach for European Union law where a Polish statute or an office's practice is not enough — and to do it effectively.

What a European law firm does

EU law is not a separate drawer — it is a layer running through administrative, immigration and business law. In our practice it means cases where EU regulations, directives and the case law of the Court of Justice of the EU (CJEU) operate alongside Polish statutes: residence legalisation, free movement of persons and services, social security coordination, recognition of professional qualifications, data protection. Reading the two legal orders together often decides the outcome.

EU law in foreigners' cases — provisions that really work

Most EU law hides where you least expect it: in an ordinary residence case. The status of EU long-term resident derives from Directive 2003/109/EC, family reunification from Directive 2003/86/EC, and the EU Blue Card for the highly qualified from Directive 2021/1883. When an office reads Polish provisions narrowly, a well-made argument from the directive and CJEU judgments can turn the case around — because the authority must interpret national law in conformity with EU law.

EU citizens and their families in Poland

An EU citizen does not need a residence card, but after three months should register their stay, and non-EU family members must obtain a residence card of an EU citizen's family member. After five years the right of permanent residence arises. We handle the cases where this seemingly simple path gets complicated: refusals of registration, mixed families, retaining the right of residence after divorce or the death of the EU citizen, benefits and insurance in two countries.

Companies and workers — posting, A1, recognition of qualifications

For businesses European law is daily reality: posting of workers within the provision of services, A1 certificates and social security coordination (Regulation 883/2004), recognition of professional qualifications (Directive 2005/36/EC), freedom to provide services in another Member State. For companies employing foreigners we combine this layer with immigration law — so that posting a non-EU worker does not end in a fine or a lost permit.

EU-law argumentation before Polish authorities and courts

EU law takes precedence over statute and many of its provisions have direct effect — Polish courts and authorities must apply them. In practice this requires precision: you must identify the right provision, show its direct effect or demand a conforming interpretation, and where doubt remains — persuade the court to refer a preliminary question to the CJEU. An EU argument made carelessly or at the wrong stage is simply lost, which is why we build it from the first letter, as we describe in the article on our administrative law firm in Warsaw.

European law in our firm's practice

In cases with an EU element we work as in all others: first an analysis of the file and a realistic assessment of chances, then a strategy and consistent conduct of the case — before the office, the appeal board, the WSA and the NSA. We serve clients in eight languages, and most foreigners' cases can be handled fully remotely. If in your case the office ignores EU provisions, book a consultation — we will check whether EU law can work in your favour.
