Questione giuridica chiave
Whether the constitutional complaint against the cantonal judgment was admissible despite the judgment being an interim decision.
Decisione estratta
The judgment was an interim decision, and no irreparable legal harm was shown because the challenged issues could still be reviewed after the final decision.
Motivazione estratta
A partial confirmation of the contribution plan did not end the proceeding; the allocation of contributions had to be recalculated. Under Art. 87 OG, a constitutional complaint against an interim decision is admissible only if it can cause irreparable legal harm, which was not the case here.
