Questione giuridica chiave
Whether the respondent could introduce a new factual allegation about the tenant's domicile in the federal public-law appeal
Decisione estratta
New facts and evidence were inadmissible; in any event, the alleged change of address was not decisive.
Motivazione estratta
A public-law appeal cannot, save exceptional circumstances not met here, be used to introduce new facts or documents. The alleged fact did not affect the outcome, so no questioning of the appellants was necessary.
