Undoing the Legal Capacities of a Military Object: A Case Study on the (In)Visibility of Civilians

International law dictates that actors in armed conflicts must distinguish between combatants and civilians. But how do legal actors assess the legality of a military operation after the fact? I analyze a civil proceeding for compensation by victims of a German‐led airstrike in Afghanistan. The court treated military video as key evidence. I show how lawyers, judges, and expert witnesses categorized those involved by asking what a “military viewer” would make of the pictures. During the hearing, they avoided the categories of combatants/civilians; the military object resisted legal coding. I examine the decision in its procedural context, using ethnographic field notes and legal documents. I combine two ethnomethodological analytics: a trans‐sequential approach and membership categorization analysis. I show the value of this combination for the sociological analysis of legal practice. I also propose that legal practitioners should use this approach to assess military viewing as a concerted, situated activity.
