Questione giuridica chiave
Whether the contractual farm rent was void under Art. 45 LBFA for exceeding the lawful amount
Decisione estratta
The rent clause was not void in civil law because no timely authority opposition under Arts. 43 et seq. LBFA was still possible when the unlawfulness became known.
Motivazione estratta
Art. 45 LBFA presupposes an authority decision fixing the lawful rent; for an agricultural immovable, only the authority may initiate opposition within the statutory deadlines. A later declaratory decision under Art. 49 LBFA cannot retroactively invalidate the lease.
