In mid-April 2005, Sichuan law enforcement and judicial authorities issued a joint opinion prohibiting the use of illegally obtained evidence, and requiring courts to exclude coerced statements and confessions if police cannot provide a rational explanation of the alleged coercion or refuse to investigate allegations of abuse.
2005年4月中旬，四川省执法和司法机关下发了联合意见，禁止使用非法获得的证据，并要求法院在警方无法对所指控的威吓提出合理的解释或拒绝对这一指控进行调查时，可排除威吓证词或口供。
