UN employees do not pay ANY taxes. In addition, the dear Judge gets some serious amounts of 'expenses' paid for him by the UN.
As a rule, people who sign up for the UNMIK gig have take home pay much greater than back home. Jeez, even Albanians complain about how overpaid & underqualified UNMIK staff is.
...and one can also earn some xtra money turning a blind eye to Albanian "mischiefs". Ask any former UN administrator.
