They don't need to worry about anyone "admitting a mistake or error in judgement", as no mistakes or errors were made.Hence there will be no compensation and all the decision makers are saying the right things to not open themselves to financial recourse from the public. AGD/Crown lawyers would have briefed them on not admitting a mistake or error in judgement.
The pizza shop owner, and anyone else who lied to the authorities, on the other hand could & probably will be bankrupted by claims of lost earnings relating directly to the lies they told.
