Case Summary: The automakers of California file a suit, seeking to prevent the enforcement of a law by California legislature that seeks to curb the emissions of carbon dioxide substantially from all automobiles within their territory. The automakers contend that a federal law exists which puts a cap on the emission of carbon dioxide indirectly, by enforcing the fuel economy standards nationwide. The manufacturers claim that natural justice is being denied to them by the harsher restrictions placed by the Californian law.
To Explain: Parties in the suit at hand.
The plaintiffs in the suit would be the group of automobile manufacturers who are against the enforcement of the Californian law, as they are the ones seeking the remedy from the court and who initiated the lawsuit. Whereas, the State of California would be the defendant in this suit, who would put forth their defense, and give reasons for the validity of the law and its enforcement, while furnishing the reasons why the plaintiff should be denied for the remedy.
