In other words- to hell with the evidence, I want to believe the worst. This is a charter for curtain-twitchers, Nosey-Parkers and Zeal-of-the-Land Busys to harass and demonise anyone they like.
On the contrary, it is all about the evidence.
My point is that just because there isn't sufficient evidence to sustain a criminal charge of assault 'beyond reasonable doubt' does not mean there is insufficient evidence to sustain a claim of gross misconduct in an employment disciplinary process 'on the balance of probabilities'.
And this isn't about 'believing the worst' it is about how the law operates in the UK and the nature of evidential tests in different types of case. In criminal cases there is a presumption of innocent - the charge is presumed not to be proven unless there is sufficient evidence to conclude 'beyond reasonable doubt' that the individual is guilty. The same does not apply in law in civil cases and in employment disciplinary cases where the starting point is neither a presumption the the charge is proven, nor not proven (in other words neither a presumption that the individual is innocent, nor guilty) - the starting point is strict neutrality. Hence the evidence test is 'on the balance of probabilities' - in other words it is more likely than not that the individual is guilty.
That's the law - if you don't like it, take it up with your friendly local legislator, but good luck with trying to change something that is a fundamental part of our legal system.
