The enshrinement of the right to an international fair trial was achieved through the most important legal instruments guaranteeing human rights, either universal international treaties with general or specialized value, or regional treaties with general or specialized value. A fair trial is one of the basic human rights. The right to a fair trial, as a social value, is necessary for any socio-human environment, and the formation of its elements in the different stages of civilization, through the adopted international acts, has seen an obvious progress, the respect by the state authorities of this right representing a guarantee for the administration of justice in the new coordinates of democratic societies. The right to a fair trial is an indispensable right to a democratic society and represents a procedural guarantee of the rights and freedoms of the person before the courts, constituting one of the premises for ensuring the principle of the preeminence of law in a democratic society.
