Questão jurídica principal
Whether the cantonal decision had to include a legal-remedy warning and whether the Federal Court could review the prison director's internal letter.
Decisão extraída
The omission of a legal-remedy warning did not matter for a constitutional complaint, and only the Justice Directorate's decision was before the Court.
Fundamentação extraída
A constitutional complaint is an extraordinary remedy, not an ordinary appeal; the internal letter was not the object of review.
