In our percent academe, the study about "in dubio pro reo" which means no punishment in doubt case is disheveled.

In China,the present laws has achieved progress in non-prosecution on suspected crime,but there stll exists some problems such as general standard of suspected crime,relevant participants lack of chances of cross-examination,and the judicial authorities disregard of procedure.

The present procedure of non-prosecution on suspected crime should be further reformed,including the aggrieved party s participation,the establishment of non-prosecution hearing system and judicial system,the introduction of state compensation system and perfection of procuration and legal aid.

The system of non-prosecution on suspected crime reflects the implementation of the presumption of innocence in China,but it also results in the uncertainty about the facts and evidences of the cases.

It is much more likely for judicial officers to compel criminal suspects to "confess and comply with law" by means that infringes on human rights in doubtful cases than in doubtless ones due to unconfirmed facts and insufficiency of evidence.

Under the 1996 amendment of the Criminal Procedure Act, principles of presumption of innocence and in dubio pro reo have been established.

In our percent academe, the study about "in dubio pro reo" which means no punishment in doubt case is disheveled.

The path of solving this conflict is that rule of law shall make an appropriate concession to common sense,the traditional idea of no punishment in doubtful cases should be loosened and the conditions of conviction should be reduced.
