Filing a case refers to a litigation activity in which the public security, judicial organs and other administrative law enforcement organs, according to their respective jurisdictions, examine the materials such as reporting, accusation, report, surrender and private prosecution, and decide to investigate or judge it as a criminal case when they think that criminal facts have occurred and need to be investigated for criminal responsibility. There are two conditions for the court to file a case. First, there are criminal facts and some behaviors that endanger society. Second, we must pursue legal responsibility.
