Re: Question
No, the standard of proof, and degree of misconduct, is much higher for the CPS.
A court/tribunal would back you if, on balance of probabilities, you were justified in dismissing someone (i.e. if there is at least a 50% chance they committed gross misconduct, or other fireable offence)
The CPS shouldn't take action unless there is a 50% chance they can convince a jury beyound reasonable doubt that a crime was committed (i.e. if there's a 50% chance you can conince a jury there is a 98%(*) chance they committed a crime)
