《贞观政要·卷五·论公平》
又规定一个案子要经过群臣、群吏、万民三次审讯，大家都认可了，才能定罪。可见，律令必然也参有人情。所以《左传》说： 大小案子，虽然不能明察，但肯定有人情的因素在里面。 
又复加之以三讯，众所善，然后断之。是以为法，参之人情。故《传》曰： 小大之狱，虽不能察，必以情。 
It was also stipulated that a case had to be examined by the ministers, the officials, and the ten thousand people three times before a guilty sentence could be handed down. Clearly, the statutes and ordinances must also take feelings into account. Thus, the Zuo Zhuan says: In trying cases, big and small, although one may not see clearly, one must certainly take feelings into account.
