The Washington Post notes Supreme Court Declines D.C. Commuter Tax Case. I am sure the court is right that the framers gave Congess full authority over the district. It is just too bad DC cannot exploit its monopoly power as national capital to tax those who live outside the district to pay for District services. This notion of “taxing foreigners living abroad” is a politically elegant way of off-loading costs in the toll-road context.
