The extensive use of judicial artificial intelligence has improved judicial efficiency and contributed to justice. However， highly intelligent and automated AI has interfered with the application of statutory judicial principles and judicial models， bringing some legal risks as well. The principle of the independent exercise of judicial power by the court is impacted by AI， the bias and opacity of algorithm affects its justice and openness， and the strengthening of the case handling ability of public authorities by AI makes the traditional stable litigation triangle structure face the risk of imbalance.The main reason for these risks is the biased positioning of judicial AI. Judicial artificial intelligence must holds onto its auxiliary position， and its governance needs to submit to the "rule-of-law naturalized technology" idea. The principle of independent exercise of judicial power should be strengthened by implementing the judicial accountability system and limiting the context of AI use； the construction of an algorithmic disclosure mechanism should be promoted to enhance judicial openness； and the use of AI to adequately safeguard the rights of the parties and enhance their litigation capacity can keep the litigation structure as balanced as possible.
