The state had the task of restoring the works to their rightful owners or their heirs; the Netherlands Art Property Foundation (SNK) was established for this purpose.
[6] Officials working for the Stichting Nederlands Kunstbezit included the Monuments Men Robert de Vries (1905-1983),Nicolaas Rudolph Alexander Vroom (1915-1995), Louis Jacob Florus Wijsenbeek (1912-1985), Karel Gerald Boon (1909-1996), David Cornelis Röell, Jonkheer (1894-1961) and the Dutch painter Otto Verhagen (1919-2003).
[7] [8] [9] [10] [11] [12] In 1998, the Origins Unknown Agency ("Herkomst Gezocht") (BHG) was established with the aim of conducting systematic research into the provenance history of all individual works of art.
[16][17][18][19] In 2002 a study was published, Betwist bezit, which was commissioned by the BHG and concluded that in the early years of the SNK the priority was not the return of looted art to its rightful owners.
[23][24][25] In 2020 a Dutch commission found the Netherlands' art restitution panel showed "too little empathy" to victims of Nazi aggression and sided too often with museums.
