The judge prompted the defendant to find any illegal evidence.

It is not illegal to present legal evidence.

Judges must exclude illegal evidence according to law and may not use it as the basis for determining the facts of a case. If the evidence obtained by seriously infringing on the legitimate rights and interests of others is still adopted, it will certainly help to win the lawsuit at the expense of seriously infringing on the legitimate rights and interests of others, violating the prohibitive provisions of the law and seriously violating public order and good customs, and the obtained evidence will be rejected as illegal evidence.
