The Role of the European Parliament in the Rulemaking Process of the EU Abstract The topic of the thesis concerns the law-making of the European Union. It intends to present the legal framework of the adoption of the adoption of legislative acts and analyse the influence caused by the practice of informal procedures on de facto the situation in this field. Within the organisation structure, the emphasis is placed on the functioning of the European Parliament and within the informal procedures on so-called trilogue negotiations. Firstly, we examine the nature of informal procedures and trilogue negotiations. Secondly, we analyse what the influence of those procedures on the factual state of affairs of the ordinary legislative procedure in the light of its de lege lata concept and thirdly we evaluate the outcome from the EU functioning principles' point of view. After the de lege lata overview and the specification of the trilogue negotiations and other modalities of the informal procedures, we analyse some typical impacts of the trilogue negotiations on the practice of the adoption of legislative acts. We conclude that the trilogue negotiations constituted the so-called early agreements practice as a standard concept of the ordinary legislative procedure and materially substituted the three readings'...

Triloger har utvecklats till att idag utgöra en viktig del av Europeiska unionens ordinarie lagstiftningsförfarande. Dessa informella förhandlingsmöten mellan unionslagstiftarna, med deltagande av kommissionen, har förändrat den praktiska tillämpningen av fördragens bestämmelser om lagstiftningsförfarandet fastän de inte omnämns i fördragen. Samtidigt som trilogerna har gjort processen mer effektiv har de haft en negativ påverkan på insynen i förfarandet. I denna uppsats studeras hur fenomenet triloger genom åren har uttryckts juridisk i den institutionella unionsrätten. Kritiken mot trilogerna och andra aktuella händelser som möjligen kan förändra trilogernas rättsliga ställning utvärderas. / Trilogues have evolved to become an important part of the European Union’s ordinary legislative procedure. These informal negotiating meetings between the Union legislators, with the participation of the Commission, have changed the practical application of the Treaty rules on the legislative procedure without being mentioned in primary law. While the trilogue system has made the process more efficient, it has had a negative impact on the transparency of the process. This paper aims to study how the trilogue phenomenon has been legally expressed in the institutional Union law. The criticism against trilogues and other recent events are also examined in order to assess how these possibly can change the legal status of trilogues. / Les trilogues ont connu une évolution en devenant une partie intégrante et importante de la procédure législative ordinaire de l’Union Européenne. Ces réunions de négociations informelles entre les législateurs européens, avec la participation de la Commission, ont modifiées l’application pratique des règles des traités sur la procédure législative sans être mentionnées dans le droit primaire. Bien que les trilogues aient rendu le processus plus efficace, ils ont indéniablement eu un impact négatif sur la transparence de la procédure. Cette thèse vise à reconstruire comment le phénomène des trilogues a été exprimé en termes légaux dans le droit institutionnel de l’Union. Les critiques à l’encontre des trilogues et d’autres actualités sont aussi étudiées afin d’évaluer la façon dont ceux-ci éventuellement peuvent modifier le statut juridique des trilogues.
