general rule is that a void law or administrative act cannot be the source of legal rights or duties., exception to this is the doctrine of operative fact

The general rule is that a void law or administrative act cannot be the source of legal rights or duties. Article 7 of the Civil Code enunciates this general rule, as well as its exception: "Laws are repealed only by subsequent ones, and their violation or non-observance shall not be excused by disuse, or custom or practice to the contrary. When the courts declared a law to be inconsistent with the Constitution, the former shall be void and the latter shall govern. Administrative or executive acts, orders and regulations shall be valid only when they are not contrary to the laws or the Constitution."

The doctrine of operative fact is an exception to the general rule, such that a judicial declaration of invalidity may not necessarily obliterate all the effects and consequences of a void act prior to such declaration.² In Serrano de Agbayani v. Philippine National Bank,³ the application of the doctrine of operative fact was discussed as follows:

The decision now on appeal reflects the orthodox view that an unconstitutional act, for that matter an executive order or a municipal ordinance likewise suffering from that infirmity, cannot be the source of any legal rights or duties. Nor can it justify any official act taken under it. Its repugnancy to the fundamental law once judicially declared results in its being to all intents and purposes a mere scrap of paper. As the new Civil Code puts it: "When the courts declare a law to be inconsistent with the Constitution, the former shall be void and the latter shall govern. Administrative or executive acts, orders and regulations shall be valid only when they are not contrary to the laws of the Constitution." It is understandable why it should be so, the Constitution being supreme and paramount. Any legislative or executive act contrary to its terms cannot survive.

Such a view has support in logic and possesses the merit of simplicity. It may not however be sufficiently realistic. It does not admit of doubt that prior to the declaration of nullity such challenged legislative or executive act must have been in force and had to be complied with. This is so as until after the judiciary, in an appropriate case, declares its invalidity, it is entitled to obedience and respect. Parties may have acted under it and may have changed their positions. What could be more fitting than that in a subsequent litigation regard be had to what has been done while such legislative or executive act was in operation and presumed to be valid in all respects. It is now accepted as a doctrine that prior to its being nullified, its existence as a fact must be reckoned with. This is merely to reflect awareness that precisely because the judiciary is the governmental organ which has the final say on whether or not a legislative or executive measure is valid, a period of time may have elapsed before it can exercise the power of judicial review that may lead to a declaration of nullity. It would be to deprive the law of its quality of fairness and justice then, if there be no recognition of what had transpired prior to such adjudication.

In the language of an American Supreme Court decision: "The actual existence of a statute, prior to such a determination of unconstitutionality, is an operative fact and may have consequences which cannot justly be ignored. The past cannot always be erased by a new judicial declaration. The effect of the subsequent ruling as to invalidity may have to be considered in various aspects, with respect to particular relations, individual and corporate, and particular conduct, private and official." This language has been quoted with approval in a resolution in Araneta v. Hill and the decision in Manila Motor Co., Inc. v. Flores. An even more recent instance is the opinion of Justice Zaldivar speaking for the Court in Fernandez v. Cuerva and Co. (Boldfacing and italicization supplied)

Clearly, for the operative fact doctrine to apply, there must be a "legislative or executive measure," meaning a law or executive issuance, that is invalidated by the court. From the passage of such law or promulgation of such executive issuance until its invalidation by the court, the effects of the law or executive issuance, when relied upon by the public in good faith, may have to be recognized as valid. In the present case, however, there is no such law or executive issuance that has been invalidated by the Court except BIR Ruling No. DA-489-03.

To justify the application of the doctrine of operative fact as an exemption, San Roque asserts that "the BIR and the CTA in actual practice did not observe and did not require refund seekers to comply with the120+30 day periods."⁴This is glaring error because an administrative practice is neither a law nor an executive issuance. Moreover, in the present case, there is even no such administrative practice by the BIR as claimed by San Roque.
