In Frett v. People, 58 V.I. 492 (V.I. 2013), the Court adopted the approach that "it is the better practice to give the instruction whenever the witnesses have strong incentives to fabricate or mold their testimony as the government desires in order to escape prosecution, lighten their sentences, obtain remuneration or receive protection" unless there is a compelling reason to omit the instruction. Id. at 514-15.
However, the Court did note that certain circumstances reduce the need for the instruction.
The Court found in Frett, for example, that the defendant was given wide latitude to challenge the credibility of the accomplice and to emphasize the accomplice's plea agreement with the People. Id. at 514.
