Question juridique clé
Whether the cantonal authority could refuse to enter the appeal for lack of current legal interest in the Easter-service matter
Solution extraite
The authority should exceptionally have dispensed with the requirement of a current practical interest because the issue could recur yet usually evade timely judicial review.
Motifs extraits
The refusal to attend a service concerns a short-lived prison situation that can repeatedly arise; requiring a current interest would in practice amount to denial of justice.
