The U.S. Supreme Court hears arguments Tuesday in an obscure tax case with potentially trillions of dollars in tax consequences for the federal budget. It is a case that has tax law specialists both gobsmacked and alarmed.
The words of the 16th Amendment to the Constitution do not roll off the tongue. Enacted in 1913, it says: "Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration."
