G.R. No. 126146 - People vs. Matignas y San Pascual

On August 7, 1990, Carmelita Panganiban (petitioner) entered into a Sublease and Dealer Agreement (SLDA) with Pilipinas Shell Petroleum Corporation (private respondent).
The agreement involved the sublease of a gasoline station located at 427 Samson Road, EDSA, Caloocan City.
The SLDA provided that Shell could terminate the agreement within the first six (6) months on grounds such as:

If the SLDA was not terminated within the six-month period, it would continue for another period (with a total period of five years or until an earlier termination as provided).

Pilipinas Shell was not the owner of the lot but merely a lessee from Serafin Vasquez under a separate Lease Agreement (February 27, 1987) effective from January 1, 1987 to December 31, 2002.
On June 14, 1995, Shell notified petitioner that the SLDA would expire on July 31, 1995, advising her to wind up her business.
Despite the notification, petitioner continued to pay rentals, wrongly believing that the agreement remained in effect until December 31, 2002, resulting in a dispute when Shell refused the collection of payments.

On July 10, 1995, petitioner filed a petition for declaratory relief with the Regional Trial Court (RTC) of Makati City (Case No. 95-1010) to clarify her right to occupy the premises.
On August 30, 1995, Shell filed an Answer in the RTC case.
On April 26, 1996, Shell filed an unlawful detainer (ejectment) case in the Metropolitan Trial Court of Caloocan City (Civil Case No. 22645), asserting the termination of the SLDA.
On April 30, 1996, Shell filed a Motion to Dismiss petitioner’s declaratory relief case on the ground that the issues of renewal and possession should be resolved in the pending unlawful detainer suit.
The Metropolitan Trial Court, on September 25, 1996, rendered a decision in favor of Shell, ordering petitioner to vacate the premises and awarding monetary relief against her.

Petitioner appealed the Metropolitan Trial Court decision, with the appeal pending in the RTC of Caloocan City (Civil Case No. C-17726).
On February 21, 1997, the RTC dismissed petitioner’s petition for declaratory relief, citing the breach of the SLDA and the pending ejectment case.
Petitioner’s motion for reconsideration was denied on April 11, 1997, after her failure to appear at the hearing.
On May 13, 1997, petitioner filed a petition for review with the Supreme Court, which was later referred to the Court of Appeals on June 25, 1997.
On November 12, 1997, the Court of Appeals denied the petition for certiorari, affirming the dismissal on the ground of litis pendentia.

The courts cited the doctrine established in Rosales v. Court of First Instance of Lanao del Norte and University Physicians Services, Inc. to dismiss the earlier declaratory relief action in favor of the illegal detainer suit.
The decision emphasized that when two suits involve the same parties, issues, and facts, the later filed suit in which the primary issue of possession is to be determined may be preferred in order to avoid multiplicity and to prevent vexatious litigation.

Whether the Court of Appeals erred in affirming the RTC’s dismissal of the declaratory relief action on the ground of litis pendentia.
Whether the fact that Shell filed its motion to dismiss (based on the same subject matter as the ejectment suit) long after filing its answer invalidates the dismissal.

The proper interpretation of the SLDA’s termination clause and its effect on petitioner’s right to remain in possession.
The appropriate forum for resolving the issues concerning possession and the expiration of the SLDA—whether it should have been the declaratory relief action or the unlawful detainer suit.
The applicability of the precedent that a motion to dismiss may be filed even after an answer has been filed when exceptional grounds exist.
