You probably havn't found it because I
remembered it wrong. It is the last clear
chance doctorine.
Doctrine of Last Clear Chance
The doctrine of last clear chance otherwise
known as the doctrine of discovered peril or
the humanitarian doctrine may be stated as
follows: Where both parties are negligent in
such a way that it would be impossible to
determine whose negligence was the proximate
cause of the accident, the party who had the
last clear chance or opportunity to avoid
the accident by the use of proper care but
failed to do so is considered in law solely
responsible for the consequences of the
accident (Picart vs. Smith 37 Phil 809; Mr.
And Mrs. Ong vs. Metropolitan Water
District, L-7694, Aug. 29, 195

There some other precedures on that page.
My point is that there are different ways of
measuring fault and the least of which is
blaming it on that person most likely
responsible.
Do they have a history of accidents? Do
they have a history of pyro technic shows.
Does the band? And where was the fire watch
person. Last I checked just about every
pyro technic show requires there be people
present with extinguishers in hand to fight
posible outbreaks. Was that material
cheaper? Or was it all that was nessesary
because the place was not designed for pyro
technics. Or was the club ripped off by a
contractor? Does the manager have a
document stating flame retardent insulation
had been installed? I don't see that there
is enough information present to decide.
I have some experience with pyro technics.
No not just blowing up lighters in the
school halls. I often act as a shooter at
firework displays around my state. I am not
licensed but my good friend is and he is the
one that brings me on shows. Anyway when we
shoot a show we all have as much of a
responsability to avoid accidents as the
next shooter or manager. It is something we
just don't want to happen. So we take every
posible precausion and anyone sees a posible
hazzard they speak up and it is investigated
immediatly. We have had no accidents. God
willing that wont change. But accidents can
happen. It is very unfortunate when
hundreds of people die as a result but I
know one thing for sure. If I were the
shooter that fired that shell that flew up
into the audience I would be greeved about
more than who is going to take the blame.
The fact that they all take such a strong
position that it wasn't their fault but
someone elses tells me they all should be
punished. Maybe next time the band will
inspect the stage first. And the manager
will do the same. If they did, well good
for them maybe they should have checked
twice. Hot flame on flamable material isn't
rocket science and someone should have
cought it before it happened. There may not
be any way of prooving who was or was not
responsible but there is one way of
decreasing the probability of it happening
again. Thats my opinion anyway, I'm sure
not everyone will agree. It would be pretty
myopic of them if they all did.
