The rise of portable electronic devices such as laptops and smart phones is made possible in part by the availability of lithium ion battery technology. Unfortunately, in some cases these batteries have caught fire and caused serious injury, and in several cases the Consumer Product Safety Commission (CPSC) has facilitated recalls of dangerous batteries. But can consumers compel the CPSC to recall a dangerous battery? Suppose that a consumer has been injured by a faulty battery, provides information about the problem to the CPSC, and asks it to take action. If the CPSC declines, can the injured person ask a court to order the CPSC to take action? What would be the likely outcome?
