When judges make judicial errors of law (those later identified by higher courts on appeal; not to be confused with judicial misconduct), they are not affected beyond possible damage to their public image, personal pride and further career development.
That is, for a judge who is happy where they sit and who doesn't care what people say, none of the consequences of making an error would be anything to worry about. Essentially, such judges will have little or no motivation to avoid making errors.
It is certainly understandable that judges cannot be made responsible for their decisions (otherwise no one would want to be a judge). However, shortage of accountability and motivation as to quality of work creates leeway for abuse of judicial power e.g. making "errors" which are not in fact made by mistake but rather consciously to covertly pursue certain interests that have nothing to do with interests of justice.
Have there been any attempts anywhere to address this particular issue by reforming the Judicature? For example, has any government attempted to enact a system of tracking and analyzing judicial errors to get judges who made them work on them and make conclusions as to how to mitigate making errors in future? Or a system that officially raises question of fitness to the job where more than certain amount of errors has been made?
