Key legal question
Whether the federal appeal could challenge the cantonal letter of 4 November 2011 itself
Extracted holding
The letter was only a non-appealable confirmation of the prior final order and could not be attacked separately.
Extracted reasoning
The earlier order of 17 August 2011 already contained the substantive prohibition and substitute-enforcement warning. The later letter merely fixed a deadline and repeated the existing enforcement consequence, without independent legal effects.
