Sit down, make up the rules.
I actually just came across an example for this the other day. It has to do with death and negative HP. Player's X, Y, and Z get blasted by a trap. LEt's say it's a fire trap. They get cooked and die. X and Y are at, say, -20 HP, while Z is at -120 HP. The kicker is, there are no clerics in the party. How does the GM handle this? Some GM's say, "Well, I hope your party members will carry your bodies out. And as for you, player Z, they're not carrying your body out, they're carrying your ashes out, because at -120 HP, there's nothing left of you." Then there are other GM's who might say, "You got fried. However, the burns aren't internal. You mostly died from the shock and pain. Your friends, with some CPR, maybe a regeneration spell from the druid, some healing potions, and good bandaging with aloe might just revive you and allow you to follow your companions, albeit in some pain for a while until the regeneration takes full effect. Yeah, so you have -120 HP, player Z, dead is dead; negative HP doesn't mean a whole lot after -11." There's an obvious inconsistency here. But in either case, is one of the GM's wrong or just making a bad call? I'd have to say no. They're in charge, because it's their game, and in both cases the answers "can be justified and (they work) within the framework and spirit of Layonara."
