- 18 - Groetzinger, 480 U.S. 23, 32 n.11 (1987) (characterizing a State lottery as “public gambling” in a case treating gambling earnings as ordinary income); United States v. Maginnis, 356 F.3d 1179, 1183 & n.6 (9th Cir. 2004) (taxpayer’s lottery winnings enter into the section 165(d) calculation as wagering gains that taxpayer’s gambling losses at the casinos can be applied to in addition to taxpayer’s gambling winnings at the casinos). Our resolution of this dispute turns mainly on a determination of the credibility of the evidence presented. The determination of the truth of a matter on the basis of the oral and documentary evidence “epitomizes the ultimate task of a trier of the facts--the distillation of truth from falsehood which is the daily grist of judicial life.” See Diaz v. Commissioner, 58 T.C. 560, 564 (1972). We “must be careful to avoid making the courtroom a haven for the skillful liar or a quagmire in which the honest litigant is swallowed up. Truth itself is never in doubt, but it often has an elusive quality which makes the search for it fraught with difficulty.” Id.; Hawkins v. Commissioner, T.C. Memo. 1993-517, affd. without published opinion 66 F.3d 325 (6th Cir. 1995). We determine the credibility of each witness, weigh each piece of evidence, draw appropriate inferences, and choose between conflicting inferences. See Neonatology Associates, P.A. v. Commissioner, 115 T.C. 43, 84 (2000), affd. 299 F.3d 221 (3dPage: Previous 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 NextLast modified: March 27, 2008
