Jewish World Congress president Ronald Lauder has publicly threatened the Kunstmuseum Bern with an "avalanche" of lawsuits if the institution accepts the collection of approximately 1,300 artworks bequeathed to it by the late Cornelius Gurlitt - stated in an article published by German weekly "Der Spiegel." The museum is currently still in the process of making this delicate decision - whether or not to accept the collection - which includes works by Henri Matisse, Max Liebermann, Otto Dix, and Marc Chagall, among others famous artists.

Gurlitt died on May 6th of this year, leaving the entire collection to the Swiss museum - but nearly 600 works from the collection are suspected to be of questionable provenance, possibly Nazi loot.
