Bar Q & A: Delay
ART. 1174. Except in cases expressly specified by the law, or when it is otherwise declared by stipulation, or when the nature of the obligation requires the assumption of risk, no person shall be responsible for those events which could not be foreseen, or which, though foreseen, were inevitable.
Article 1165. When what is to be delivered is a determinate thing, the creditor, in addition to the right granted him by article 1170, may compel the debtor to make the delivery. If the thing is indeterminate or generic, he may ask that the obligation be complied with at the expense of the debtor.
