禁止刑讯,不仅是为了保障公民的人身权利,更是宪法上人性尊严价值的彰显。德国宪法学对刑讯是否应予绝对性禁止的讨论,核心在于对人性尊严如何予以理解。与对刑讯应予绝对禁止的通说不同,晚近德国宪法学界提出了刑讯禁止相对化的观点。刑讯禁止相对化理论中引入了比较衡量,其背后蕴含着对人性尊严价值绝对性的挑战。 Prohibition of torture is not only to protect citizens’ personal rights, but also to highlight the value of human dignity in the Constitution. The discussion of whether the German constitutional law should absolutely prohibit torture lies in how to understand human dignity. Different from the general prohibition of torture, the late German constitutional academia put forward the view that the prohibition of torture should not be relativized. The introduction of comparative measures in the theory of prohibition of torture prohibits the challenge posed by the absolute value of human dignity.
