Admins who resigned voluntarily, under uncontroversial circumstances, can ask to skip RfA. Upon a review to confirm that the user both was in good standing at the time of the de-adminship and is in good standing currently, a bureaucrat may restore access rights. If there is any question that reinstatement would lack community [[Wikipedia:Consensus|consensus]], the user will be referred to RfA. The guiding principle for such decisions, per [[WP:CRAT]], is that bureaucrats may grant adminship only when doing so reflects the wishes of the community.
