(b)….” [9] Insofar as the impugned notices in items 2, 3 and 4 are concerned, the address stated is the address for the defendant’s place of business (see SSM search dated 14.1.2021, Exhibit “NSML-1” affirmed by Nani Suhana Binti Mohd Lazim dated 25.8.2021, Enclosure 9) which was the Page 7 of 14 last known address of the defendant during the period in 2017 to early 2019. [10] As for the impugned notice item 1, the address stated therein was the last known address of the defendant based on a form CP204 filled by the defendant’s tax agent (Peter Chong Tax Services (KL) Sdn Bhd) to the IRB which IRB had received on 29.11.2007 (see Exhibit “AZ-1” the Afidavit Sokongan Azraf Bin Azmi affirmed on 11.5.2022, Enclosure 24). [11] With regard to the impugned notices items 5, 6 and 7, the plaintiff has explained that in late 2018, the defendant’s tax agent (TC Commercial Tax Services Sdn Bhd) had been in communication with the IRB and the tax agent’s address was provided as the correspondence address for the defendant which was the last known address of the defendant (see Exhibit “AZ-2” the Afidavit Sokongan Azraf Bin Azmi affirmed on 11.5.2022, Enclosure 24). [12] Based on the documents/exhibits adduced in the supporting affidavits (Enclosures 9, 11 and 24) of the plaintiff, this Court is satisfied that the plaintiff had by way of ordinary post sent all the impugned notices to the defendant’s respective last known addresses during the material Page 8 of 14 time. Hence, according to s. 145 (2) of the Act, those impugned notices were deemed to have been served to the defendant. [13] In Kerajaan Malaysia v Neraca Untung Sdn Bhd [2009] 1 LNS 575, para 17, the Court of Appeal held: “The notice must be deemed or presumed to have been served on the Respondent. The Respondent has failed to rebut the presumption. It is nor [sic] disputed that the last known address of the Respondent was provided by the Respondent's tax agent personally. Hence, the Respondent's claim that the 1997 (Additional) notice was not received cannot hold water.” [14] Likewise, in the present case, the defendant did not adduce any evidence to satisfy this Court to make a finding that the deeming provision has been rebutted. The defendant merely denied having received the impugned notices (see paragraphs 5(a), 9(a), 13, 15 of Afidavit Jawapan Defendan affirmed by one Muhammad Hafiz Bin Johari dated 8.9.2021, Enclosure 10). The defendant did not justify why the last known addresses on the record of the IRB were incorrect or that the defendant had notified the IRB of the latest correspondence address at the material times and years the impugned notices were sent to the defendant. Page 9 of 14 [15] Based on the above findings, this Court finds the first issue raised by the defendant’s counsel is untenable. Second Issue: Validity of the Certificate of Indebtedness [16] With regard to this second issue, the defendant’s counsel avers that the Certificate of Indebtedness dated 25.8.2021 was signed by one Rohaizan Binti Jumat for and on behalf of the Director General of the IRB. The “Surat Kuasa” issued under s. 136(5) of the Act to Rohaizan Binti Jumat was dated 23.5.2008 which was signed by the then Director General of IRB Dato’ Hasmah Bt. Abdullah. [17] The defendant’s counsel further avers that as at 25.8.2021, when the Certificate of Indebtedness was issued, the Director General of IRB at that material time was Datuk Seri Sabin Bin Samitah. Hence, the Certificate of Indebtedness issued on 25.8.2021 could not be valid because “the written authorisation to exercise the function of the Director General in issuing the Certificate of Indebtedness ought to be issued by Datuk Seri Sabin Bin Samitah, he being the sitting Director General at that material time.” Page 10 of 14 [18] Section 136(5) of the Act states: “(6) Where a public officer or an employee of the Inland Revenue Board of Malaysia exercises any of the Director General's functions by virtue of any provision of subsections
