Article 31 of the Lawyers Law of the People's Republic of China*** and the State Lawyers Law, lawyers acting as defenders shall, in accordance with the facts and the law, safeguard the procedural rights and other lawful rights and interests of criminal suspects and defendants.
Law, like other social sciences, differs markedly from the natural sciences in that not every question has a single correct answer. There are many things in life that do not necessarily have a standard and definitive answer. The discipline of law is centered on the choice of values, even when two values, both of which need to be protected by the law, are in conflict, and the law has to decide which value needs to be protected more. It is inevitable that different people may have different understandings of the law, and it is not a question of who is right and who is wrong, but which value needs the protection of the law more at this point in history today. Therefore, it is inevitable that different people will have different understandings of the law. Thus, in the courtroom, the lawyer, based on his or her duty, will understand the law in favor of the defendant, and the prosecutor, also based on his or her duty, will understand the law in a way that is unfavorable to the defendant, and the judge, in the middle, will adjudicate. The process of adjudication, that is, trial, is the process of the judge's comprehensive consideration of all factors, although the lawyers and prosecutors do not give way to each other, each of them, but the process of the court hearing in a confrontational manner, but the most fair trial process. This process enables the defendant to put his own defense, through the lawyer, a legal professional, expressed in the language of the law, and this process, but also enables the judge to think more comprehensively about the case and the application of the law.
So, in the trial process, the lawyer does not represent evil or justice, but only a legal point of view in favor of the defendant, and similarly, the prosecutor does not represent justice or evil, but a legal point of view unfavorable to the defendant. In this way, the trial judge can synthesize the two points of view, its decision, both the defendant fully for their own defense, but also will make the judge for the law will be a more comprehensive understanding.
