G.R. No. 160067/G.R. No. 170410/G.R. No. 171622. November 17, 2010.
NELSON IMPERIAL, ET AL., Petitioners, vs. MARICEL M. JOSON, ET AL., Respondents. (Consolidated Cases)

FACTS

A tragic vehicular accident occurred on May 11, 2001, in Sariaya, Quezon, involving an Isuzu truck driven by Santos Francisco (owned by Nelson Imperial), a Fuso truck driven by Santiago Giganto, Jr., and a Kia Besta van driven by Arnel Lazo. The collision resulted in multiple fatalities, serious injuries, and property damage. Consequently, a criminal case for Reckless Imprudence was filed against Francisco and Imperial.
Multiple civil actions for damages ensued. Petitioners Francisco and Imperial filed a complaint against Giganto and the Fuso truck owners before the Regional Trial Court (RTC) of Naga City (Civil Case No. 2001-0296). In retaliation, respondents Giganto and the Josons filed a damages complaint against the petitioners before the Metropolitan Trial Court (MeTC) of Valenzuela City (Civil Case No. 8314). Separately, the injured passengers and heirs of the deceased van passengers filed their own complaint for damages against petitioners before the RTC of Parañaque City (Civil Case No. 01-0325). Each set of parties moved to dismiss the others’ complaints primarily on the ground of litis pendentia, arguing that the multiplicity of suits over the same incident was improper.

ISSUE

The principal issue is whether the doctrine of litis pendentia warrants the dismissal of the subsequently filed civil cases to avoid multiplicity of suits.

RULING

The Supreme Court denied the petitions, ruling that litis pendentia was not present to justify dismissal. The legal logic is anchored on the requirements for litis pendentia: identity of parties, identity of rights asserted and relief prayed for, and identity with respect to the two preceding particulars such that any judgment rendered in the other action will amount to res judicata. The Court found these elements lacking.
Critically, there was no identity of parties. The three civil cases involved different constellations of plaintiffs and defendants asserting distinct rights and liabilities arising from their respective roles in the accident. The Naga case was filed by the Isuzu truck interests against the Fuso truck interests. The Valenzuela case was the Fuso truck interests’ counter-action against the Isuzu truck interests. The Parañaque case was filed by the van victims solely against the Isuzu truck interests. Each suit sought relief based on different legal obligations and relationships (e.g., owner-driver liability, quasi-delict). A judgment in one case would not constitute res judicata for the others, as the parties and causes of action were not identical.
The Court emphasized that the consolidation of these related cases before a single court was the proper procedural recourse to achieve efficiency and avoid conflicting decisions, not dismissal via litis pendentia. The RTC of Parañaque, having acquired jurisdiction over the case filed by the numerous victims, was in the best position to consolidate all related civil actions for a unified resolution of all liabilities arising from the singular accident.
