1. The Washington Principles of 1998 and the mutual declaration of the Federal government, states, and municipal umbrella organizations of 1999 are endorsed.
2. There is unanimity that provenance research must be strengthened in Germany. Museums and cultural institutions are asked to carry out systematic, comprehensive provenance research, something to which their supporting agencies have committed themselves. The agencies supporting museums must provide sufficient funds to allow provenance research to be carried out. Existing deficits are to be worked off as quickly as possible. The results must be publicized promptly and are to be published in the freely accessible Lost Art Internet Database.
3. The Federal Republic of Germany’s commitment under the Washington Principles and the mutual declaration of 1999 must now be realized in practice. In an individual case, that means that the prerequisites for fair and just solutions must be created in on-going restitution proceedings. However, this also means that the proceedings must be transparent.
4. In contested cases, the Advisory Commission chaired by Professor Limbach should be able to issue recommendations, even where requested by only one party. The Commission’s recommendations and the detailed grounds on which they are based are to be published.
5. Participants in the conference recommend, almost 10 years after the Washington Declaration, that a follow-up conference be organized at which the participating states present their experience and at which, if necessary, proposals for improved procedures in implementing the Washington Declaration be adopted.
