According to Yang, the problem lies in incorrect implementation of the regulations. "The law clearly states that lawyers and court officials who contribute to miscarriages of justice should be held responsible, but it is extremely difficult to do that in practice," he said.

"Holding individuals to account for their mistakes would be an important way of ensuring that justice is done, and in promoting the rule of law," he added.

"Knowing that they could shoulder the blame would ensure that officials do their jobs to the best of their abilities and would also help to avoid miscarriages of justice."

Although more miscarriages of justice are being overturned than ever before, legal professionals say the sums awarded for the mental anguish endured as a result of wrongful imprisonment are inadequate, as Cao Yin reports.
