I am not sure where you get this idea of hijack from and obviously cannot comment on the correlation between your recent experience and this case. But in post no. 40 you cited clause 146 from the ANO and implied it applied to the pilot. I am pretty sure 146 is there to ensure the CAA or other regulator/law enforcement agency is not impeded in performing an investigation/enquiry/prosecution in their duties of enforcing the ANO. Which is why it is under the general section not the Operating of Aircraft Section
