Joseph McKenna, Magoun v. Illinois Trust Savings Bank…
“ An inheritance tax is not one on property, but one on the succession; (2) the right to take property by devise or descent is the creature of the law, and not a natural right,-a privilege,-and therefore the authority which confers it may impose conditions upon it. From these principles it is deduced that the states may tax the privilege, discriminate between relatives, and between these and strangers, and grant exemptions, and are not precluded from this power by the provisions of the respective state constitutions requiring uniformity and equality of taxation. ”
