A Supreme Court majority found in *West Virginia v. EPA* that the federal agency lacked authority to make bold assertions of authority based on old vague statutes in areas where Congress clearly chose not to act. Will Yeatman authored Cato’s [brief](https://url.avanan.click/v2/___https://www.cato.org/legal-briefs/west-virginia-v-epa___.YXAzOmNhdG9pbnN0aXR1dGU6YTpvOjVmMTFjODUxMjI5MzgwYWZlMmQzY2E5NzIzNDc2N2ZiOjY6YjU5NjoyMmM1NTA0YTI3YzUwZDM2ODVhMDhlNjI3NmJjNDZlYmE5ZGI1ZmNlYTRhZTM4ZGNkZDM0MjA0Y2RmODJjNTY0Omg6Rg) in the case.
