Andrew Mellon is a name well-known to historians and, probably, most tax lawyers. See Wikipedia page, here.

Mellon v. Commissioner, 36 B.T.A. 977 (1937), here. Robert Jackson, Wikipedia here, who later became Supreme Court Justice and chief prosecutor at the Nuremberg Trials, led the BTA case for the IRS. The BTA rejected the IRS claim of fraud (36 B.T.A., at 1054-1055.
