This end of year report aims to present a picture of the provisional Eurojust Unit, its work and some important results during the first ten months of its existence. The Unit and its activity have been described in earlier reports of March to June, July, August to September and October, which were published under a restricted cover. These reports complement each other and together provide an analysis of the early months and the way in which the Unit operates. In this report the main focus will be on general conclusions about the operational work and the results during the period from March to December 2001. It will also describe the experience of the Unit so far. Finally the report will suggest some future expectations.
