At the request of the parties or with their consent, the arbitration tribunal may, if it also considers oral hearings unnecessary, hear and decide a case on the basis of documents only.

但经双方当事人申请或者征得双方当事人同意，仲裁庭也认为不必开庭审理的，仲裁庭可以只依据书面文件进行审理并作出裁决。

For a documents-only arbitration, the written objection shall be raised prior to the expiry of the time limit for the submission of the first defence.

书面审理的，应当在首次答辩期限届满前以书面形式提出。
