As the double pillars of Centrality of trials,the confrontation clause and the hearsay rule prevailed in the middle ages as a result of the blood sin and continued in England common felony trials.It required a capital sentence be based on the justices’ public conscience acquired in the court instead of his private conscience out of the court or the dossiers regardless of its reality,and its aim was to protect the justices from the fatal sin.Comparatively,the dossiers,functioning as factfinding,factfixing and factreproducing,prevailed in Europe common felony trials and in England high treason trials in 1617th century when the state security overcame the blood sin.However,since the middle of 17th century when the human rights rose and the state security fell,the centrality of trials returned to England high treason trials and functioned as concealing the truth and preserving the rule of law.If the criminal justice is aimed at factfinding,the dossiers with the selfknowing information in them will win and the centrality of trials loses,for the latter’s only function is restricted to singling out few policeframing information by Crossexamination in public courts.China has no centrality of trials tradition in its culture and its criminal justice has been aiming at factfinding,as a result,the dossiercentered model is inevitable.In order to activate the reform of Centrality of trials in China criminal justice,it’s necessary to abandon the factfinding and rebuild the function of the reform.
