Abstract: | The International Covenant on Civil and Political Rights reflects the world's perception of human rights, and is of vital importance in the field of international human rights. The Covenant has been signed by Chinese government. Although not ratified yet, it will definitely have an impact on the reform of China's Criminal Law. Therefore, it is necessary to further change our notion of the criminal law system by defining the boundary between public power and civil rights and developing the view of human rights protection. In terms of the specific system, it is necessary to further reduce the number of crimes punishable by the death penalty and limit the application of the death sentence, improve China's Criminal Procedural Law to protect the fundamental rights of suspects and defendants in terms of compulsory measures, investigation means and judicial form, and add some charges like enslavement and illegal human experimentation, which are criminalized around the world, so as to be in line with the requirements of international human rights protection. |
