John Marshall Harlan II,
Harper v. Virginia Board of Elections…
“ My disagreement with the present decision is that in holding the Virginia poll tax violative of the Equal Protection Clause the Court has departed from long-established standards governing the application of that clause.The Equal Protection Clause prevents States from arbitrarily treating people differently under their laws. Whether any such differing treatment is to be deemed arbitrary depends on whether or not it reflects an appropriate differentiating classification among those affected ”
