No matter whether the defendant entrusts himself or is appointed by the judicial organ, once he becomes the defendant's lawyer, he shall not refuse to defend or represent him without justifiable reasons. This is a clear provision of China's lawyer law and lawyer's practice norms. The so-called justifiable reasons are also clearly defined in relevant laws and regulations.

Lawyers have the right to refuse to defend or represent.
