Part of the reason why this may have dragged on on this that the company is not that well placed.
Take the worse case, an internal disciplinary finds the Captain guilty of deliberately causing the cancellation of the flight. CitiExpress dismiss the Captain.....
The Captain then takes the company to an employment tribunal and cites unfair dismissal. The law is interesting in this area. If a claimant can prove that the company dismissed them for raising concerns over safety then the dismissal is automatically deemed unfair.
In the event that someone is dismissed for raising concerns over safety a Tribunal can award damages, there is no cap or upper limit ie they can be punative.
Plus all ther very bad publicity attached to a public case etc etc.
I imagine the stress of being placed under suspension for all this time has been very stressful and will have had an impact the health of the Captain concerned. Again something that should be addressed by BALPA.
Hope a satisfactory outcome is achieved regards BP
