With reference to inadequacy of representation, the cases are clear in saying that a conviction will be held invalid on such grounds only if representation by counsel was a farce or a sham. State v. Brown, 107 Ariz. 375, 489 P.2d 12 (1971); Monsour v. Cady, 342 F. Supp. 353 (D.C. Wis. 1972). See also, State v. Burton, 16 Ariz. App. 61, 490 P.2d 1189 (1971); State v. Bustamante, 103 Ariz. 551, 447 P.2d 243 (1968).
