Joseph McKenna, Heim v. McCall — Opinion of the Court
“ To sustain the charge of unconstitutionality the 14th Amendment is adduced and the specification is that the law abridges the privileges and immunities of the contractors and those of their alien employees in depriving them of their right of contracting for labor, and that the state of New York, by enacting and enforcing the law, deprives employers and employees of liberty and property without due process of law, and denies to both the equal protection of the law. ”
