Questão jurídica principal
Whether the appeal to the cantonal government was late because earlier letters were appealable decisions.
Decisão extraída
The earlier letters were not formal decisions; the only appealable decision was the 2 February 2007 letter, so the appeal was timely.
Fundamentação extraída
The July, August, and 5 October 2006 letters were preliminary or confirmatory communications without binding effects, without proper formalities, and without appeal instructions. Treating them as final decisions was arbitrary and contrary to the authority's own conduct and to good faith.
