"A prosecutor should not be compelled by their supervisor to prosecute a case where he or she has a reasonable doubt about the guilt of the accused."
This is an ABA Ethics standard (Standard 3-3.9), so not a primary authority. Since it's non-binding, what does this standard look like in practice?
Do associate DA's ever refuse to prosecute despite their supervisor's instructions? If they're fired for insubordination, do they have any legal grounds for recompense or rehiring? What does this actually look like in the real world?
