Illegally obtained witness testimony should be excluded. Such illegal evidence obtained by means of serious violation of witness's human rights should be forcibly excluded.

Witnesses should take the initiative to write objective facts and hand them over to the retrial court through prison judicial procedures. If there is enough new evidence to overturn the original judgment or ruling, the proportion of cases with reasons for retrial is low, and there are not many cases in which the complainant attacked the facts found in the original trial by submitting new evidence, which does not exceed 5% of the total number of cases, but once they enter the retrial, the rate of revision is high.
