Summary of "Obligations 15: Loss of the Thing Due (Extinguishment)"

Main ideas / concepts

Topic: “Loss of the thing” as a ground for the extinguishment of obligations (legal doctrine).
When a thing is considered “lost”: if it
- perishes,
- goes out of commerce, or
- disappears such that its existence is unknown or it cannot be recovered.
General rule: If a specific thing is lost without the debtor’s fault and the debtor is not liable, the obligation is extinguished.
Key limitation: Loss does not extinguish the obligation—and the debtor remains liable—in several specified situations.
Partial loss: Courts decide whether the partial loss is:
- substantial enough that the “substance” of the obligation is not met (extinguishment), or
- negligible enough that the obligation remains (obligation still due).
Presumption of fault: If the thing was in the debtor’s possession and gets lost, the debtor is presumed at fault, except in certain situations (e.g., calamity/fortuitous events).
Obligations to do (services): “Loss of the thing” also relates to doing/services—extinguishment occurs when performance becomes legally or physically impossible without debtor fault.
Article 1267 (difficulty of performance): If performance becomes manifestly beyond the contemplation of the parties, the debtor may be released in whole or in part (analogized to an “impracticability/changed circumstances” doctrine, as referenced in subtitles).

Rules and exceptions (detailed)

A) Loss extinguishes an obligation when all apply

The obligation is extinguished when:

The obligation involves a specific thing (specific in nature).
The thing is lost (perishes / goes out of commerce / disappears such that it can’t be recovered or its existence is unknown).
The loss is without the fault of the debtor.
The debtor is therefore not in a position of liability for the loss.

B) Loss does not extinguish the obligation if any apply

If the law provides debtor liability
- Article 1170: debtor is liable for loss when the debtor is guilty of fraud, negligence, delay, or contravenes the tenor of the obligation.
- Article 1165 (as described): if the debtor promised to deliver the same thing to two or more persons with different interests, the debtor is liable—even if the thing is lost—for:
  - the value of the thing, and
  - damages if warranted.
There is an express stipulation
- If the parties agreed the debtor will be liable for loss, then loss does not extinguish the obligation.
Assumption of risk is part of the obligation’s nature
- If the nature of the obligation requires the debtor to assume the risk, loss does not extinguish it.
The obligation arises from a crime
- If delivery arises from a crime, loss does not extinguish; the debtor remains liable.
The thing is generic
- Generic thing principle (Latin maxim mentioned):
  - “Gener… net never perishes” (exact wording unclear due to subtitle errors).
- Meaning: If the object is generic (e.g., a sack of rice with no unique identifying characteristics), loss of one unit does not extinguish the obligation because the debtor can still supply another of the same kind and quality.

C) Partial loss

Courts evaluate whether partial loss is:
- Negligible/small → obligation subsists (still due as substantially met), or
- So significant that it affects the substance of the obligation → the court may declare the obligation extinguished.

D) Presumption when the thing is lost while in the debtor’s possession

General presumption: the debtor is at fault, so the debtor will be liable.
Exception: the debtor is not liable if loss is due to calamity or fortuitous events.
Subtitles also reference exceptions connected to earlier topics, including cases involving:
- generic things, and
- delay scenarios.

Obligations to do (performance/service)

“Loss” and extinguishment principles can apply when performance becomes:

legally impossible, or
physically impossible,
without the debtor’s fault.

Example concept (as given): If performance is prevented because it would require the debtor to violate law (or otherwise commit a wrong), performance becomes effectively impossible and the obligation may be extinguished.

Article 1267 / difficulty beyond contemplation (release in whole or in part)

Article 1267 (as stated)

If performance becomes so difficult that it is manifestly beyond the contemplation of the parties, the debtor may be released in whole or in part.

Analogy / example (changed circumstances)

The subtitles describe a “changed circumstances / conditions cease to exist” type principle.
Example used: Black Plague / bubonic plague
- Parties contract assuming normal conditions.
- An unforeseen event later makes performance extremely difficult (e.g., transport/commerce disrupted).
- The parties may be released because they did not contemplate performing under those new conditions.

General condition described

Parties stipulate based on existing norms/conditions.
When additional conditions arise or conditions cease, release may occur in whole or in part.
