Article 1680

The lessee shall have no right to a reduction of the rent on account of the sterility of the land leased, or by reason of the loss of fruits due to ordinary fortuitous events; but he shall have such right in case of the loss of more than one-half of the fruits through extraordinary and unforeseen fortuitous events, save always when there is a specific stipulation to the contrary.

Extraordinary fortuitous events are understood to be: fire, war, pestilence, unusual flood, locusts, earthquake, or others which are uncommon, and which the contracting parties could not have reasonably foreseen. (1575)
