Because the content of the ruling is not available, it is unknown on what grounds the Guangdong Higher People's Court decided to send this case back for retrial. However, according to previous reports, "due to the clear facts of the case, the second trial court, Guangdong Higher People's Court, adopted a non-public trial method, and the case was reviewed in writing by a three-judge panel."
It can be presumed that the ruling was not made based on the first clause of Article 189.
