Mon, sometimes the claimants are involved, deliberately defrauding insuring companies to get a 'free' ride back to Kathmandu (most often). However, other times they are not the prime scammers and are duped or persuaded that an evacuation by guides seeking a fat kick-back from the helicopter companies. They are then taken to hospital for all that over-investigation and kept almost as prisoners because the hospital takes possession of theor passport until the insurance company pays or the 'patient' does.
The innocent suffer of course in the form of increased premiums - or large excesses for heli evacuation - but you know all this Mon!
Eric, yes it could be worse than a financial penalty, possible refusal of an evacuation when it is necessary because of concerns of a fraudulent claim. Deaths could follow as a result.
My prediction of an outcome of the Ministry's investigation: diddly squat.
