Harlan F. Stone,
Educational Films Corporation of America v…
“ Under the Constitution the privilege of exercising the corporate franchise is the legitimate object, and the immunity of federal instrumentalities from taxation, a legitimate restriction, of the state power to tax. To give both to the power and to the immunity such a practical construction as will not unduly restrict the power of the government imposing the tax, or the exercise of the functions of the government which may be affected by it, is the problem necessarily involved in determining the extent of the immunity. ”
