Questione giuridica chiave
Whether the constitutional complaint could challenge the lower cantonal decisions beyond the last cantonal judgment.
Decisione estratta
Only the last cantonal decision could be reviewed; the request to annul the lower decisions was inadmissible.
Motivazione estratta
A constitutional complaint generally lies only against final cantonal decisions. Departure from that rule was unnecessary for full protection because the last cantonal instance had the relevant issues before it.
