Decision I 16 G.R. Nos. 271059, 271347, E-02472 and
E-04036
In Araullo v. Aquino,483 the Court explained the doctrine of operative·
fact as one rooted in justice and equity. It provides for the prospective
application of the Court's decision when the consequences are too significant
to undo:
The doctrine of operative fact recognizes the existence of the law or
executive act prior to the determination of its unconstitutionality as an
operative fact that produced consequences that cannot always be erased,
ignored or disregarded. In short, it nullifies the void law or executive act
but sustains its effects. It provides an exception to the general rule that a
void or unconstitutional law produces no effect. But its use must be
subjected to great scrutiny and circumspection, and it cannot be invoked to
validate an unconstitutional law or executive act, but is resorted to only as
a matter of equity and fair play. It applies only to cases where extraordinary
, .circumstances exist, and only when the extraordinerry circumstances have
• met the stringent conditions that will permit its application 484 (Citations

The Court in Araullo485 found the doctrine of operative fact applicable
to the adoption and implementation of the Executive Department's DAP. The
Comiheld:
As already mentioned, the implementation of the DAP resulted into
the use of savings pooled by the Executive to finance the P APs that were
not covered in the GAA, or that did not have proper appropriation covers,
as well as to augment items pertaining to other departments of the
Government in clear violation of the Constitution. To declare the
implementation of the DAP unconstitutional without recognizing that its
prior implementation constituted an operative fact that produced
consequences in the real as well as juristic worlds of the Governmentpnd
the Nation is to be impractical and unfair. Unless the doctrine is held to
apply, the Executive as the disburser and the offices under it and elsewhere
•as the recipients could be required to undo everything that they had
implemented in good faith under the DAP. That scenario would be
enormously burdensome for the Government. Equity alleviates such
burden.
The other side of the coin is that it has been adequately shown as to
be beyond debate that the implementation of the DAP yielded undeniably
positive results that enhanced the economic welfare of the country. To
count the positive results may be impossible, but the visible ones, like public
infi-astructure, could easily include roads, bridges, homes.for the homeless,
h~spitals, classrooms and the like. Not to apply the doctrine ol operative
fact to the DAP could literally cause the physical undoing of such worthy
·results by destruction, and would result in most undesirable wastefulness. 486
