If I was de-briefing this crew I would be talking about the decision making process long before I would discuss the CRM issues.
Methinks you don't really understand what CRM is really all about. With two crew operations the decision should be jointly agreed.
SASless has it right with his statement
"One Dissenting Vote Rule". However, this is not as NeerG rN would have it a "voting system", in this case it means if either pilot is not happy with a situation you should get out of it soonest and discuss the problem later over a cold beer........
NeerG rN - other than being a reversed indication, you aren't by any chance an ex- military pilot?
