Abstract
Selective conscientious objection, a refusal to participate in a specific war due to reasons of conscience, has recently gained attention. A combatant confronted with such a decision needs guidance to help decide whether and how to object. Furthermore, those judging a combatant’s objection or failure to object need guidance. After introducing the prima facie duty override criteria, I will apply the criteria to the case of selective conscientious objection. Ultimately, I argue that the jus ad bellum criteria rebranded as the prima facie duty override criteria can help provide guidance regarding selective conscientious objection.
