Regulations should be passed based on necessity-which should be to protect the public from danger and promote a healthy planet. If "cost" is reviewed by a non-expert panel it is almost certain that they will not take the full cost of not implementing the regulation into account. For example, the cost of not implementing a regulation to protect clean water must take into account the health cost to people as well as the cost to the ecosystem (fish, loss of wetlands, loss of biodiversity, etc) .
