Inasmuch as the filing of a motion for reconsideration interrupts the 30-day period within which to file a petition for certiorari with this Court, petitioner has effectively consumed seven days of the abovestated 30-day period when he filed his motion for reconsideration. Thus, as correctly pointed out by private respondent, when petitioner received a copy of the assailed COMELEC En Banc Resolution, he only had 23 days from December 4, 1998, the date when he received the COMELEC En Banc Resolution, or until December 27, 1998[16], to file the instant petition for certiorari. This petition was filed on January 4, 1999. In any event, whether the petition was filed on time or not, an examination of the records leaves us satisfied that public respondent COMELEC did not commit grave abuse of discretion in dismissing the petition for disqualification. First, on the issue of due process, we find no violation thereof when public respondent COMELEC decided to dismiss the petition for disqualification without hearing. Well-established is the rule that the essence of due process is simply an opportunity to be heard. [17] In Zaldivar vs. Sandiganbayan[18], cited in the recent case of Bautista vs. COMELEC[19], we held that the right to be heard does not only refer to the right to present verbal arguments in court. A party may also be heard through his pleadings. Where opportunity to be heard is accorded, either through oral arguments or pleadings, there is no denial of procedural due process. Furthermore, the filing by petitioner of a motion for reconsideration accorded him ample opportunity to dispute the findings of the COMELEC First Division, so that he was as fully heard as he might have been had oral arguments actually taken place. Deprivation of due process cannot be successfully invoked where a party was given the chance to be heard in his motion for reconsideration. [20] Next, petitioner re-asserts before us the sufficiency of his evidence to prove that private respondent influenced the Mandaluyong City public school teachers, through his father, Abalos, Sr., in the performance of their functions as members of the BEIs.
