Abstract: As an important part of the new Criminal Procedure Law, the confiscation procedures for illegal income has a great theoretical and practical controversy. The essence of the confiscation procedures for illegal income is the criminal procedure. Judicial interpretation of the scope of application violates the principle of procedure law and basic principle. The "confiscation" of the confiscation procedures for illegal income is "special confiscation". There are two specific objects of proof: one is that a criminal suspect or defendant escapes and cannot present in court after being wanted for a year, or a criminal suspect or defendant dies, The other is that there is practical connection between the facts of the crime accused and the property to be confiscated. The interpretation of "illegal income" and "other property" should follow the principle of practical connection.
