The people's court that originally tried the case is responsible for transferring the case file, relevant evidence and appeal to the people's court at a higher level.

If the defendant, private prosecutor, plaintiff and defendant in incidental civil action directly appeal to the people's court of second instance, the people's court of second instance shall submit the appeal to the people's court of first instance within three days. The people's court shall transmit it to the people's procuratorate at the same level and the other party. Then transfer it to the higher court together with the case file of first instance and relevant evidence. The people's court at a higher level can decide how to try the case only after receiving the case file of first instance and relevant evidence.
