In my class Research for Environmental Agencies and Organizations I offer students a list of projects, and each semester I include something about lead poisoning prevention. One student signed on to help me promote a bill that is now before the Massachusetts legislature, submitted by Senator Patricia Jehlen, similar to a bill she submitted many years ago. The intent of the bill is to overcome the barriers to suing those who recklessly placed lead in commerce, knowing it will harm people, and doing nothing to prevent that harm. If companies make a product that they ought to know would likely harm people, the law should provide for both compensation to victims and punishment for those who unreasonably cause harm, so that others will be deterred from doing the same thing. But when you can’t prove that the harm you experienced was caused by a particular company that company gets away with their malfeasance. The bill that Jehlen put forth many years ago would have imposed “market share liability”, allowing the apportionment of liability according to the market share a company had of that product, treating all the members of industry who behaved the same way as culpable. The current bill allows the court more flexibility to determine how to allocate responsibility, but it’s the same idea: no one should get away with such anti-social behavior simply because the specific product maker can’t be identified.
