Ok, so what are these burning issues of interest?
Negligence? None, no incident, therefore how can anyone be held resposible for it?
Offences? Who knows, insufficent information. Possibly one of two, but irrelevent realy as police didn't attend. Possibly an offence under the ANO, but again irrelevent as there can be no evidence. Interesting defence, in the absence of a breath test and presumably a blood test...'I use John Smiths as aftershave' Prove otherwise.
Suspended for not taking a breath test? Management have no power to require a breath test. Therefore any half decent solicitor will sort it out with no problem.
Should he have been suspended earlier? Yes, obvious really.
Any other interesting points?
