The tail pound from your mine leaked and now my farm land is useless. I should be able to sue the coal company for the economic value of my land and income it could have generated for my family for the next 10 generations and if the coal company goes bankrupt I should be able to collect from the share holders in proportion to the remaining liability and stock they own.
What about the share holders who sold out before the leak was discovered? What if the owner died and the money was passed on to heirs? What about the ones that moved to another country? Let's say the leaking pond contaminated your drinking water, and coincidentally two of your children have mental development disorders, which of course you can never prove came from that leak? How much cash is worth that?
