If a person's behavior constitutes a crime, it can be tried as a case. Therefore, cases in which several people commit crimes do not have to be tried together, but can be tried separately. However, it is easier to find out the facts when such cases are tried together, which usually saves judicial resources and reduces the burden of litigation.
* * * There is no clear legal provision on whether criminal cases are merged or separated. This is the basic concept of crime and case. There are two or more people, and there are certainly more than two cases about their crimes. Different cases can naturally be tried separately, but reasons need to be given for the joint trial.
