Howell Edmunds Jackson,
Pollock v. Farmers' Loan Trust Company Hyde…
“ There is to my mind little or no real difference between denying the existence of the power to tax incomes from real and personal estate, and attaching such conditions and requirements to its exercise as will render it impossible or incapable of any practical operation. You might just as well in this case strike at the power to reach incomes from the sources indicated as to attach these conditions of apportionment which no legislature can ever undertake to adopt, and which, if adopted, cannot be enforced with any degree of equality or fairness between the common citizens of a common country. ”
