Citizenship?

The reasoned explanation requirement of administrative law, after all, is meant to ensure that agencies offer genuine justifications for important decisions, reasons that can be scrutinized by courts and the interested public.  Accepting contrived reasons would defeat the purpose of the enterprise.  If judicial review is to be more than an empty ritual, it must demand something better than the explanation offered for the action taken in this case.
