Short answer. It falls with it. Article 1230 provides that the nullity of the principal obligation carries with it that of the penal clause. A penalty provision cannot survive on its own once the underlying obligation it was meant to secure is void, since the penalty has nothing left to attach to.

The penal clause cannot outlive what it secures
Article 1230 is explicit: the nullity of the principal obligation carries with it that of the penal clause. A penal clause exists only as an accessory to a principal obligation, imposing a penalty if that obligation is breached or performed late. If the principal obligation itself is void, whether for lack of a lawful object, absence of consent, or any other ground that makes a contract void from the start, there is no valid obligation left for the penalty to reinforce. The penal clause does not somehow become an independent obligation capable of standing on its own once the thing it was attached to disappears.
Why this runs the opposite direction from a void penalty
Article 1230 states this rule alongside its opposite: a void penal clause does not drag the principal obligation down with it, but a void principal obligation does drag the penal clause down. The asymmetry makes sense once you see what each provision depends on. The principal obligation defines what the parties actually owe each other and can exist without any penalty attached at all. The penal clause, by contrast, has no independent purpose; it only reinforces an obligation that must already be valid for the penalty to have anything meaningful to secure.
What it means for you in practice
If the obligation you were relying on turns out to be void, you cannot fall back on the penalty clause as an alternative source of recovery, since a void principal obligation takes the penalty down with it automatically. Any demand for the penalty amount would have no legal foundation left to stand on once the underlying obligation is void. Whoever is defending against enforcement of a penalty should therefore look closely at whether the principal obligation itself was validly formed in the first place, because a successful challenge to the principal obligation resolves the penalty question as well, without needing a separate fight over the penalty clause's own validity or drafting.
