If a context of injustice is proven or assumed, then the question of restitution or, in the case of human remains, repatriation arises quite soon. In these cases, the entitled heirs or the societies of origin must be identified. Even if statutes of limitations can already be invoked, it remains our moral duty, demanded by society as well as politics, to deal with the issue and to strive for such restitution or repatriation. This has been the general consensus at least since the Washington Principles. On December 3, 1998, following the Conference on Holocaust-Era Assets, 44 states signed this legally non-binding agreement. The aim of the voluntary commitment is to identify looted art, to locate pre-war owners or heirs and to arrive at "just and fair solutions". If the initial focus was on the Nazi period, these objectives now apply to all contexts of injustice, to the colonial period as well as to the former Soviet Occupation Zone (SBZ) or the GDR.
