After the judgment of a criminal case takes effect, can family members visit the detention center?

If the detention center informs family members to visit, under normal circumstances, it should be that the judgment has taken effect and the parties have handed it over for execution. According to the law, in criminal cases, family members of detained parties are not allowed to visit before the court decision takes effect, and only lawyers can be entrusted to meet with them, and family members can visit only after the judgment takes effect. According to the description of the problem, it may be that after the appeal against the first-instance judgment, the court of second instance has not held a court session to make a second-instance judgment, which is final and takes effect from the date of delivery, so the detention center will notify family members to visit. In addition, because there is already a defender, the family members of the parties can directly know the specific situation from the defender. Defenders should have the judgment or ruling of the court of second instance and know the progress of the case. Article 223 of the Criminal Procedure Law The people's court of second instance shall form a collegiate bench to hear the following cases: (1) an appeal case in which the defendant, the private prosecutor and their legal representatives have objections to the facts and evidence ascertained in the first instance, which may affect conviction and sentencing; (2) An appeal case in which the defendant was sentenced to death; (3) Cases protested by people's procuratorates; (4) Other cases that should be heard in court. If the people's court of second instance decides not to hold a hearing, it shall interrogate the defendant and listen to the opinions of other parties, defenders and agents ad litem. The people's court of second instance may hear an appeal or protest case in the place where the case occurred or in the people's court that originally tried the case. The Supreme People's Court's Interpretation of the Application of the Criminal Procedure Law of People's Republic of China (PRC) Article 324 If a case of second instance is not heard in court according to law, the defendant shall be interrogated and the opinions of other parties, defenders and agents ad litem shall be listened to. All members of the collegial panel shall read out the opinions on marking and submit written opinions when necessary.
