What is being played out

One hundred and twenty-six restitution cases are currently being investigated by OIMAP's restitutions unit. They concern works of every kind and parties of every origin: museums, States, families, communities, collectors.
Each case follows a five-step course: admissibility, investigation, negotiation, decision, return. The average duration is fourteen months, but some cases are settled in three months and others take more than three years.
This page describes the state of the portfolio and how the parties follow progress.

The steps of a case
Admissibility checks that the request is complete and falls within OIMAP's competence. Investigation gathers the evidence, hears the parties and commissions experts. Negotiation seeks an agreement. The decision comes, failing agreement, through mediation or arbitration. The physical return organises the handover of the work.
Each step gives rise to a report sent to the parties. They may at any time ask for clarification or make observations.



Nature of cases
The most numerous cases concern thefts from collections or museums, sometimes old, where the work has reappeared on the market. Next come looted archaeological objects, claimed by States of origin, then historical spoliations, which require long and painstaking archive work.
A few cases concern illicit exports, where a work left a State in breach of its legislation. Their handling depends on the law of the State of origin and the applicable conventions.
Following your case
The parties have a secure space on the Desk. They check progress there, file documents, exchange with the case handler and receive summonses. A dashboard shows the next steps and expected deadlines.
Information on ongoing cases is confidential. Only aggregated statistics are published, and a few cases are presented with the parties' agreement when they are of educational interest.
Sensitive cases
Some cases, notably those concerning historical spoliations or property from colonial contexts, have a political and memorial dimension. They are handled by a dedicated team, with the support of historians and specialised lawyers.
Confidentiality is stronger there, and negotiated solutions take various forms: definitive return, long-term loan, copy or sharing. The aim is a lasting solution, accepted by all parties.
