Today, it is no longer enough to proclaim that man has rights, or even that the perpetrators of serious violations of these rights commit crimes before the whole of humanity. Henceforth, the constitutions of the States, as well as the international legal instruments, treaties and conventions have the ambition to fight the violations of the rights and to facilitate the prosecution of their authors, and this, with the aim of putting the human person at the shelter by organizing effective mechanisms of promotion and protection of the rights and freedoms related to the nature of the man.This book will therefore explore the fundamental rights and freedoms as they are proclaimed and protected in the Congolese constitutions, including the latest born of Congolese constitutional law (the transitional constitution of April 4, 2003 and that of February 18, 2006, as amended in 2011), as well as some prospects for the effectiveness of the mechanisms put in place for the improvement of the human rights situation in the DRC.
