The present paper attempted to present, through the jurisprudence used both by the Court of Justice of the European Union and by the General Court, a panorama of steps which in a careful and precise manner attempted to offer the evolution of private individuals' appeals to European justice. Does this mean an increase in appeals? Have we new limits to access to justice? Is this a more attentive and eclectic jurisdictional protection? What are the enforcement measures? These are some of the topics for discussion, evaluation and development offered based on Art. 263, letter. 4 TFEU after the Treaty of Lisbon.
