Use ～か否か as the formal, written counterpart of ～かどうか when framing a yes-or-no question as an issue to be judged, decided, or verified. It is at home in reports, contracts, minutes, and formal email, and in stiff spoken registers like board meetings or press statements; in casual conversation it sounds affected. It typically marks the pivotal point of a decision, so it pairs with verbs like 判断する・検討する・決定する・見極める.
