Who are the parties (the plaintiffs and the defendant) in this lawsuit? Are the plaintiffs seeking a legal remedy or an equitable remedy? What is the primary source of the law that is at issue here?

Reviewing: Law and Legal Reasoning

Suppose that the California legislature passes a law that severely restricts carbon dioxide emissions from automobiles in
that state. A group of automobile manufacturers files suit against the state of California to prevent the enforcement of
the law. The automakers claim that a federal law already sets fuel economy standards nationwide and that fuel economy
standards are essentially the same as carbon dioxide emission standards. According to the automobile manufacturers, it
is unfair to allow California to impose more stringent regulations than those set by the federal law. Using the informa–
tion presented in the chapter, answer the following questions.

1. Who are the parties (the plaintiffs and the defendant) in this lawsuit?
