The Aarhus Convention of June 25, 1998, of the United Nations Economic Commission for Europe on access to information, public participation in decision-making and access to justice in environmental matters, introduced the commitment of each signing State to ensure, within the framework of its national regulation, that citizens could suit and appeal any decision, or any action or omission that falls within the scope of public participation regarding issues on environmental matters. Hence, citizens are entitled to appeal administratively and judicially against public environmental decisions if they invoke a legal infringement in relation to this issue. Access to justice for violation of the rights of public participation are set out in the same terms on Regulation (EU) number 1367/2006, of September 6, relating to the application, to the institutions and community bodies, of the provisions of the Aarhus Convention on access to information, public participation in decision-making and access to justice on environmental matters. Although the right of access is quite broad, it is not exempt from exceptions, such as those indicated on the Directive 2003/4/EC of the European Parliament and of the Council, of January 28, on public access to environmental information, which has recently been interpreted by the Court of Justice of the European Union on the Judgement (First Chamber) of January 20, 2021 in the Land Baden-Württemberg case (Communications internes). However, all this is not useful if citizens are not granted with the possibility of accessing to control judicially administrative decisions that do not comply with environmental policies with the same extension, because the opportunity for any citizen to be entitled to effectively control these actions is being excluded. This paper aims to analyze the extent of the right of citizens to participate digitally in public decision-making of an environmental nature, and determine if such right is consistent with the possibilities of access to justice in this matter, since only through judicially control of the administrative decisions it is possible to make the participation right effective.
