business and will be prosecuted as principal if, with knowledge of the business, its purpose and effect, he consciously contributes his efforts to its conduct and promotion, however slight his contribution may be. … [28] By its rulings, the Court thereby affirmed the validity of the assailed penal and procedural provisions of Rep. Act No. 8042, including the imposable penalties therefor. Until the Court, by final judgment, declares that the said provisions are unconstitutional, the enforcement of the said provisions cannot be enjoined. The RTC Committed Grave Abuse of Its Discretion Amounting to Excess or Lack of Jurisdiction in Issuing the Assailed Order and the Writ of Preliminary Injunction The matter of whether to issue a writ of preliminary injunction or not is addressed to the sound discretion of the trial court. However, if the court commits grave abuse of its discretion in issuing the said writ amounting to excess or lack of jurisdiction, the same may be nullified via a writ of certiorari and prohibition. In Social Security Commission v. Judge Bayona,[29] we ruled that a law is presumed constitutional until otherwise declared by judicial interpretation. The suspension of the operation of the law is a matter of extreme delicacy because it is an interference with the official acts not only of the duly elected representatives of the people but also of the highest magistrate of the land. In Younger v. Harris, Jr.,[30] the Supreme Court of the United States emphasized, thus: Federal injunctions against state criminal statutes, either in their entirety or with respect to their separate and distinct prohibitions, are not to be granted as a matter of course, even if such statutes are unconstitutional. No citizen or member of the community is immune from prosecution, in good faith, for his alleged criminal acts. The imminence of such a prosecution even though alleged to be unauthorized and, hence, unlawful is not alone ground for relief in equity which exerts its extraordinary powers only to prevent irreparable injury to the plaintiff who seeks its aid. 752 Beal v. Missouri Pacific Railroad Corp., 312 U.S. 45, 49, 61 S.Ct. 418, 420, 85 L.Ed. 577. And similarly, in Douglas, supra, we made clear, after reaffirming this rule, that: “It does not appear from the record that petitioners have been threatened with any injury other than that incidental to every criminal proceeding brought lawfully and in good faith …” 319 U.S., at 164, 63 S.Ct., at 881.
