Article 236 of Civil Code

A person who, in order to avert a grave and imminent danger threatening himself or another in person, honor, or property, and in whose creation he had no part, is compelled to cause damage to another person's property that is less serious than that which he sought to avert, shall not be liable to compensate for that damage unless recovery is impossible on the basis of unjust enrichment at another's expense. In that event, the person causing the damage shall be obliged only to pay appropriate compensation assessed by the judge having regard to the circumstances and the requirements of justice.
