Hong Kong protests: ‘joint enterprise’ doctrine urged by prosecutors could implicate those not at scene of illegal gathering, riot
- Interpretation sought stems from first riot case over 2019 anti-government movement in which three defendants were acquitted
- If applied, defence lawyers argue driver of a car or supplier of resources could also be charged if those they aided went on to commit crimes

Without seeking a reversal of these acquittals, prosecutor Eric Kwok Tung-ming SC on Monday argued for the application of the common law doctrine of “joint enterprise”, on the basis that it had not been in any way excluded by the provisions that created the two offences commonly used in prosecuting protesters.
Kwok said the application was not limited to those present at the scene, as the phrase “takes part in” used in the Public Order Ordinance implied secondary liability – covering those who aid or abet the crime – and the requirement of assembling together applied only to the principle offender.
The interpretation, if accepted, would implicate participants who were not physically present – such as a lookout, a driver of a getaway car or a supplier of resources – as well as those who were only arrested at a certain distance away from the scene after pursuit.
