You doubt it would be an issue? On the contrary, it would be the issue that would bbq the defense.
"Your Honor, I was under duress . . . my house was on fire."
"Ok, I'll allow your lawsuit against the fire department to proceed."
It wouldn't even be a speedbump.
I doubt it would go to court, but since the whole court thing is just being thrown around on this thread, it doesn’t even matter.
