Joseph McKenna, Indian Territory Illuminating Oil Company v…
“ A tax upon the leases is a tax upon the power to make them, could be used to destroy the power to make them. If they cannot be taxed as entities they cannot be taxed vicariously by taxing the stock, whose only value is their value, or by taking the stock as an evidence or measure of their value, rather than by directly estimating them as the Board of Equalization and the referee did. The assessment by the Board was of the leases as objects of taxation, having no immunity under Federal law. ”
