5/28/2020 E-Library - Information At Your Fingertips: Printer Friendly law, judgment or order shall not be applied. Additionally, prohibitive laws concerning persons, their acts or property, and those which have for their object public order, public policy and good customs shall not be rendered ineffective by laws or judgments promulgated, or by determinations or conventions agreed upon in a foreign country. The public policy sought to be protected in the instant case is the principle imbedded in our jurisdiction proscribing the splitting up of a single cause of action. Section 4, Rule 2 of the 1997 Rules of Civil Procedure is pertinent — If two or more suits are instituted on the basis of the same cause of action, the filing of one or a judgment upon the merits in any one is available as a ground for the dismissal of the others. Moreover, foreign law should not be applied when its application would work undeniable injustice to the citizens or residents of the forum. To give justice is the most important function of law; hence, a law, or judgment or contract that is obviously unjust negates the fundamental principles of Conflict of Laws.[48] Applying the foregoing, even if the laws of the Netherlands neither enforce a parent’s obligation to support his child nor penalize the non-compliance therewith, such obligation is still duly enforceable in the Philippines because it would be of great injustice to the child to be denied of financial support when the latter is entitled thereto. We emphasize, however, that as to petitioner herself, respondent is no longer liable to support his former wife, in consonance with the ruling in San Luis v. San Luis,[49] to wit: As to the effect of the divorce on the Filipino wife, the Court ruled that she should no longer be considered married to the alien spouse. Further, she should not be required to perform her marital duties and obligations. It held: To maintain, as private respondent does, that, under our laws, petitioner has to be considered still married to private respondent and still subject to a wife's obligations under Article 109, et. seq. of the Civil Code cannot be just. Petitioner should not be obliged to live together with, observe respect and fidelity, and render support to private respondent. The latter should not continue to be one of her heirs with possible rights to conjugal property. She should not be discriminated against in her own country if the ends of justice are to be served.
