Under the two doctrines I mentioned, if none of the other miscreants involved have enough dough to pay off the judgment, than the toilet manufacturer will get stuck with the bill, as they will be judged to have the deepest pockets.
Also under strict liability the manufacturer is liable, no matter how idiots abuse, misuse, or improperly modify their products.
Strict liability is an excuse for frivolous lawsuits and needs to be eliminated. I understand the legal concept, but despite trying many times, I remain unable to understand those who would steal simply because the law permits that theft.
