The best way to prevent miscarriages of justice is to let the law be what it is.

This is what Shen Deyong, executive vice-president of the Supreme People's Court, says in a signed article commenting on several verdicts that were overturned recently.

In one of them, a villager called Zhao Yanjin in North China's Hebei province was wrongly sentenced to life imprisonment for hiring someone to kill a child in 2001. She was held in custody for a total of 10 years until she was acquitted early this year.
