Questione giuridica chiave
Whether the federal appeal against the cantonal order on a cost advance was admissible after the order had been replaced by a later decision.
Decisione estratta
The appeal was no longer admissible because the challenged order had been superseded by the later order of 5 November 2012, rendering the appeal moot.
Motivazione estratta
The impugned order of 10 September 2012 was replaced by the later order, so there was no longer a live object of review.
