A cause of action is the act or omission by which a party violates a right of another.[24] A complaint states a cause of action when it contains three essential elements: (1) a right in favor of the plaintiff by whatever means and whatever law it arises; (2) the correlative obligation of the defendant to respect such right; and (3) the act or omission of the defendant violates the right of the plaintiff. If any of these elements is absent, the complaint becomes vulnerable to a motion to dismiss on the ground of failure to state a cause of action.[25]
Evidently, all the above elements of a cause of action are alleged in the complaint: (1) the legal right of the respondent over the subject property foreclosed premised on the fact that she is the sole heir of one of the owners who is entitled to the right of redemption; (2) the correlative obligation of defendant DBP, as the foreclosing entity, to respect such right of redemption; and (3) the act or omission of the defendant in violation of the legal right, i.e., the act of DBP and its co-defendant Zarate to cause the ostensible foreclosure of the subject property and the subsequent execution of a deed of conditional sale between the defendants even prior to the lapse of redemption period to deprive respondent’s mother of her right over the property.
