Weather declines by Med Crew  

We have all heard of the 3 to Go - 1 to say No rule, where any member of the HAA team can decline a flight for weather etc. I like that rule and always abide by it. However sometimes when weather is above minimums and improving I've had a few nurses tell me weather is too bad to go. I then have to decline the flight for weather over the radio.

No body in management questions the wx call, the med crew go back to bed and no one is aware of why the flight was declined.

I saw a post on a different thread where one guy says he declines for the '3 to go, 1 to say no rule' over the radio when it is a med-crew call. Is this a company policy, or something you would consider using to hold the med-crew responsible?
