Federal Cloud Corporation Charter
Edward Everett operates a state tax processing firm that competes with a new federally chartered corporation created to handle electronic federal tax filings and interstate e-commerce records. He sues to block the corporation's operations. The charter stands because Congress selected the corporate form as a convenient instrument to execute its taxing and commerce powers.
State Transit Wage Mandate
Elise Everly manages a metropolitan transit authority that must comply with a federal statute setting minimum wages for employees engaged in interstate operations. She argues the law invades traditional state functions. The statute is sustained because Congress may choose means that are rationally related to regulating commerce among the states.

Frequently Asked

No. The clause is auxiliary and permits Congress only to select means for carrying into execution its enumerated powers. It does not authorize legislation that lacks a connection to a specifically granted power.
May Congress charter corporations under the Elastic Clause?+
Yes. Congress may charter a corporation when doing so constitutes a convenient means of executing enumerated powers such as taxing, borrowing, or regulating commerce.
What test determines whether a statute is a valid exercise of authority under the Elastic Clause?+
A statute is valid if it is plainly adapted to a legitimate end within Congress's enumerated powers and is not prohibited by the Constitution.
Can the Elastic Clause justify federal legislation that reaches purely local noneconomic activity?+
No. The clause cannot supply authority when the underlying regulation of noneconomic intrastate activity exceeds the commerce power or other enumerated powers.
