O This objective article (re) discusses the principles of legitimisation of criminal law doctrine, such as the purported Law Science, as well as the foundations of the power to punish itself, focusing primarily on the limits and possibilities of criminal law dogmatics in the current legal context. It should also be noted that it is not possible to suffer from any kind of care, which is that an emergency criminal law context, consisting of the mosaic of arbitrariness accompanying the punitive cure of contemporary criminal legislation, is solidily solidified. Thus, far from establishing a negative and meaningless position – given that there is a normal tendency to criticise what is not accepted, without first verifying the substance of its assumptions and reasons – when examining the theoretical bases of criminal dogmatics, its objectives and functions, with a focus intrinsically linked to the aims of criminal law, the argument put forward here is critically concluded. Keywords: Human dignity. Principle of criminal legality. Principle of equality in criminal matters. Criminal-law dogmatic. Punitive power.
