if you eliminate corporate personhood, you eliminate all legal accountability. corporate personhood is a legal fiction that was created to allow corporations to be sued. so, corporations can now no longer be sued in these places. it's going to be interesting to see how the court reacts.
i somehow doubt that people that argue against corporate personhood understand any of this.
