There is some theoretical uncertainty in the predictions for {ital CP}-violating hadronic asymmetries in neutral-{ital B} decays to {ital CP} eigenstates due to the existence of penguin diagrams. Using isospin relations, we show that it is possible to remove this uncertainty for the decays {ital B}{sub {ital d}}{sup 0}{r arrow}{pi}{pi}.
