Article 28 of China's Lawyers Law stipulates: "When a lawyer acts as a defender of a criminal case, he shall provide materials and opinions to prove the innocence, lighter or mitigated criminal responsibility of the criminal suspect and defendant according to facts and laws, and safeguard the legitimate rights and interests of the criminal suspect and defendant".
Generally speaking, lawyers should truthfully defend criminal suspects in accordance with the law, but lawyers are not obliged to reflect the unfavorable situation to the public security law!
Lawyers can choose the plot or legal basis that is beneficial to the criminal suspect as a breakthrough in defending the criminal suspect.
