O roli orzecznictwa TSUE w procesie harmonizacji prawa Unii Europejskiej z prawem krajowym

Upon entry into force of the accession treaty, Poland – as a member state of the European Union – became bound by the body of EU law (the acquis communautaire), including its primary and secondary law as well as the interpretation of EU law contained in the Court of Justice of the European Union case-law. Due to a very close approximation of Polish legislation to EU law – resulting from the obligation to consider, employ, and apply in the process of implementing the former a number of EU legal acts, i.e. regulations, directives, as well as acts of soft law such as guidelines and recommendations that are not acts of common law – the problem of the scope of application of EU law within the Polish legal system has occurred; this problem, or a gap in the legal sense, has been addressed and resolved, to a large extent, by case-law of the CJEU.
