Self-defense, entrusted defense and designated defense.
The defense system is generally aimed at criminal suspects or defendants.
Needless to say, the first two situations are mainly explained here. Designated defense means that the people's court appoints a defender to defend the defendant when there are legal circumstances in the trial stage of a criminal case. The legal situation that the people's court should appoint a defender for the defendant refers to: 1 blind deaf-mute or person with limited capacity; (2) He was under the age of 65438 08 at the time of trial; People who may be sentenced to death. In other words, in these three cases, whether you refuse or not, you must have a defender to participate in the end. In other cases, you can defend yourself.
