The presented article is an attempt to take part in the discussion about the importance of freedom of assembly for a democratic society. On the one hand, the freedom of assembly will be discussed as a substantive right belonging to everyone. On the other hand, the tendency of each authority to use the hard form of legal positivism and lecturing the law in this way causes the law can become an instrument of lawlessness. The author’s intention is to present the widest possible universal problem of the rule of law at the junction of freedom and power. The article presents differences in the meaning of law between advocates of the theory of the natural law and proponents of legal positivism.
