AbstractThe legislation of civil litigation in our country does not stipulate a principle of no additional responsibility resulting from appeal because it will change the status in litigation between courts and both parties. However, the principle is propitious to the improvement of civil litigation system and the reformation of model, which is also propitious to protect the right of appellants. Thus, it needs to add a incidental to an appeal and improve the information system when establishing the principle.
