According to this BBC article, the European Union translation backlog is becoming a serious problem. EU beaurocrats have been told to keep documents to fewer than 15 pages to help translators get caught up. According to the article:

Prior to EU enlargement on 1 May, there was a backlog of 6,000 pages still awaiting translation -- but with enlargement this problem has increased tenfold.

With Estonian, Czech, Hungarian, Latvian, Maltese, Lithuanian, Polish, Slovak and Slovene now on the list of official EU languages there are an estimated 60,000 pages to plough through
