"Throughout its history, the constitutional basis of the FLSA has remained anchored in the Commerce Clause. However, despite the legitimacy of that purpose, the FLSA has been the subject of constant attacks since its inception, the most fervent of which has been the challenge to its constitutionality on state sovereignty grounds.
"Two recent United States Supreme Court cases construing the constitutionality of the FLSA and its amendments reflect not only the changing judicial posture toward extension of the Act to matters of state concern, but also the differing attitudes toward extension of the Commerce Clause itself."
