G.R. No. 155622 - Dotmatrix Trading vs. Legaspi

Petitioners: Dotmatrix Trading, represented by its proprietors Romy Yap Chua, Renato Rollan, and Rolando D. Cadiz, engaged in the buying and selling of commodities including day-old chicks.
Respondent: Rommel B. Legaspi, under the trade names Big J Farms and RBL Farm, acted as supplier of day-old chicks from September to December 2001.

During the supply period, a controversy arose over the alleged overpayment and underdelivery of day-old chicks.
In May 2002, the respondent sent a demand letter seeking payment for delivered chicks.
Petitioner Cadiz replied, asserting that although a payment of ₱1,360,000.00 had been made, only ₱1,136,150.00 worth of chicks had been delivered, leaving a deficiency of ₱223,850.00.
The petitioners demanded either the delivery of the deficient quantity or the refund of the overpayment.

On June 11, 2002, petitioners filed Civil Case No. 9354 before RTC-Tarlac for the recovery of the alleged overpayment, along with claims for moral and exemplary damages and attorney’s fees.
On June 19, 2002, the respondent initiated a separate suit, Civil Case No. 489-M-2002 before RTC-Malolos, demanding the balance of ₱218,100.00 on the ground that the petitioners had underpaid for the delivered chicks.

Shortly after being served with the summons and complaint in Civil Case No. 9354 (on August 21, 2002), the respondent filed a motion to dismiss the case on the basis of litis pendentia.
RTC-Tarlac, on September 2, 2002, granted the motion to dismiss, holding that the complaint in Civil Case No. 9354 was merely anticipatory and defensive – designed to preempt the respondent’s later collection action in Civil Case No. 489-M-2002.

Petitioners contended that their action was not aimed at preemption but at vindicating the wrong allegedly committed by the respondent through overpayment.
The respondent maintained that the established jurisprudence on litis pendentia clearly holds that when two actions involve the same parties and arise from the same transaction, the later or defensive action should yield, regardless of the order of filing.

Whether Civil Case No. 9354, the action for the alleged overpayment filed by the petitioners, should be dismissed on the ground of litis pendentia in view of the parallel pending action (Civil Case No. 489-M-2002) initiated by the respondent.

Whether the two suits involve identical parties, causes of action, and reliefs, such that the decision in one would have res judicata effect in the other.
Whether the filing of the petitioners’ complaint was a preemptive and anticipatory maneuver to forestall the respondent’s collection suit.
The appropriateness of maintaining the collection case as the proper vehicle for resolving the substantive dispute.
