What does it mean to be convicted by auxiliary law and punished as a crime?

It means that the existence, severity and punishment of crimes should be judged according to the law.

This means that when convicting and sentencing, we must strictly follow the legal provisions to ensure the fairness and legality of the judgment. This principle embodies the idea of equality before the law and emphasizes the important role of law in maintaining social order and safeguarding citizens' rights and interests.
