The grant of a TPO ex parte cannot, therefore, be challenged as violative of the right to due process. Just like a writ of preliminary attachment which is issued without notice and hearing because the time in which the hearing will take could be enough to enable the defendant to abscond or dispose of his property, in the same way, the victim of VAWC may already have suffered harrowing experiences in the hands of her tormentor, and possibly even death, if notice and hearing were required before such acts could be prevented. It is a constitutional commonplace that the ordinary requirements of procedural due process must yield to the necessities of protecting vital public interests, among which is protection of women and children from violence and threats to their personal safety and security. It should be pointed out that when the TPO is issued ex parte, the court shall likewise order that notice be immediately given to the respondent directing him to file an opposition within five (5) days from service. Moreover, the court shall order that notice, copies of the petition and TPO be served immediately on the respondent by the court sheriffs. The TPOs are initially effective for thirty (30) days from service on the respondent. Where no TPO is issued ex parte, the court will nonetheless order the immediate issuance and service of the notice upon the respondent requiring him to file an opposition to the petition within five (5) days from service. The date of the preliminary conference and hearing on the merits shall likewise be indicated on the notice. The opposition to the petition which the respondent himself shall verify, must be accompanied by the affidavits of witnesses and shall show cause why a temporary or permanent protection order should not be issued. It is clear from the foregoing rules that the respondent of a petition for protection order should be apprised of the charges imputed to him and afforded an opportunity to present his side. x x x. The essence of due process is to be found in the reasonable opportunity to be heard and submit any evidence one may have in support of one's defense. "To be heard" does not only mean verbal arguments in court; one may be heard also through pleadings. Where opportunity to be heard, either through oral arguments or pleadings, is accorded, there is no denial of procedural due process.14 Petitioner also assails that there is an invalid delegation of legislative power to the court and to barangay officials to issue protection orders. Section 2 of Article VIII of the 1987 Constitution provides that "the Congress shall have the power to define, prescribe, and apportion the jurisdiction of the various courts but may not deprive the Supreme Court of its jurisdiction over cases enumerated in Section 5 hereof." Hence, the primary judge of the necessity, adequacy, wisdom, reasonableness and expediency of any law is primarily the function of the legislature.15 The act of Congress entrusting us with the issuance of protection orders is in pursuance of our authority to settle justiciable controversies or disputes involving rights that are enforceable and demandable before the courts of justice or the redress of wrongs for violations of such rights.16 As to the issuance of protection order by the Punong Barangay, Section 14 pertinently provides: SEC. 14. Barangay Protection Orders (BPOs); Who May Issue and How. – Barangay Protection Orders (BPOs) refer to the protection order issued by the Punong Barangay ordering the perpetrator to desist from committing acts under Section 5 (a) and (b) of this Act. A Punong Barangay who receives applications for a BPO shall issue the protection order to the applicant on the date of filing after ex parte determination of the basis of the application. If the Punong Barangay is unavailable to act on the application for a BPO, the application shall be acted upon by any available Barangay
