4/1/2020 E-Library - Information At Your Fingertips: Printer Friendly clause singles out one classification of OFWs and burdens it with a peculiar disadvantage.[27] Moreover, this Court held therein that the subject clause does not state or imply any definitive governmental purpose; hence, the same violates not just therein petitioner's right to equal protection, but also his right to substantive due process under Section 1, Article III of the Constitution.[28] Consequently, petitioner therein was accorded his salaries for the entire unexpired period of nine months and 23 days of his employment contract, pursuant to law and jurisprudence prior to the enactment of R.A. No. 8042. We have already spoken. Thus, this case should not be different from Serrano. As a general rule, an unconstitutional act is not a law; it confers no rights; it imposes no duties; it affords no protection; it creates no office; it is inoperative as if it has not been passed at all. The general rule is supported by Article 7 of the Civil Code, which provides: Art. 7. Laws are repealed only by subsequent ones, and their violation or non-observance shall not be excused by disuse or custom or practice to the contrary. The doctrine of operative fact serves as an exception to the aforementioned general rule. In Planters Products, Inc. v. Fertiphil Corporation,[29] we held: The doctrine of operative fact, as an exception to the general rule, only applies as a matter of equity and fair play. It nullifies the effects of an unconstitutional law by recognizing that the existence of a statute prior to a determination of unconstitutionality is an operative fact and may have consequences which cannot always be ignored. The past cannot always be erased by a new judicial declaration. The doctrine is applicable when a declaration of unconstitutionality will impose an undue burden on those who have relied on the invalid law. Thus, it was applied to a criminal case when a declaration of unconstitutionality would put the accused in double jeopardy or would put in limbo the acts done by a municipality in reliance upon a law creating it.[30] Following Serrano, we hold that this case should not be included in the aforementioned exception. After all, it was not the fault of petitioner that he lost his job due to an act of illegal dismissal committed by respondents. To rule otherwise would be iniquitous to petitioner and other OFWs, and would, in effect, send a wrong signal that principals/employers and recruitment/manning agencies may violate an OFW's security of tenure which an employment contract embodies and actually profit from such violation based on an unconstitutional provision of law. elibrary.judiciary.gov.ph/thebookshelf/showdocsfriendly/1/36914 7/11
