Right of access to documents is an integral part of the legal framework seeking to ensure democracy and transparency of the EU decision-making process. The paper discusses the evolution of this right in the European legal order focusing on the EU institutions activities dealing with three essential aspects: the gradual ‘constitutionalization’ of a fundamental right of access to information for citizens, the extension of this right beyond EU citizens to “any natural or legal person residing or having its registered office in a Member State” and finally the movement towards a position of facilitating such access to information via digital means.
