Basically, “a conflict exists when an attorney is placed in a situation conducive to divided loyalties.” Smith v. Lockhart, 923 F.2d 1314, 1320 (8th Cir. 1991); accord State v. Atley, 564 N.W.2d 817, 834 (Iowa 1997) (Lavorato, J., dissenting). We think that, under this standard, an actual conflict of interest existed in the present case.
Unlike the joint representation of codefendants, where there may be a benefit to preserving a united defense, in the case of dual representation of the defendant and an adverse witness, there is no benefit to common representation. To the contrary, the potential for less zealous representation of the defendant is obvious.
