98In the second place, as far as concerns the considerations of a general nature advanced in the contested decision, first, it must be noted, as regards the assertion that access, during a trilogue, to the fourth column of the documents at issue would increase public pressure on the rapporteur, shadow rapporteurs and political groups, that, in a system based on the principle of democratic legitimacy, co-legislators must be held accountable for their actions to the public. If citizens are to be able to exercise their democratic rights they must be in a position to follow in detail the decision-making process within the institutions taking part in the legislative procedures and to have access to all relevant information (judgment of 22 March 2011, Access Info Europe v Council, T‑233/09, EU:T:2011:105, paragraph 69). Furthermore, Article 10(3) TEU states that every citizen is to have the right to participate in the democratic life of the Union and that decisions are to be taken as openly and as closely as possible to the citizen. Thus, the expression of public opinion in relation to a particular provisional legislative proposal or agreement agreed in the course of a trilogue and reflected in the fourth column of a trilogue table forms an integral part of the exercise of EU citizens’ democratic rights, particularly since, as noted in paragraph 72 above, such agreements are generally subsequently adopted without substantial amendment by the co-legislators.
