Questione giuridica chiave
Whether the complaint could rely on new factual and legal allegations not properly raised below.
Decisione estratta
Such allegations are generally inadmissible; the complainants failed to show they had been raised in a procedurally proper way before the appellate court.
Motivazione estratta
In constitutional complaint proceedings, new matter is excluded unless properly preserved; mere references to first-instance filings do not satisfy the duty of substantiation.
