36 Printing of the construction certificate. Mr O'Brien agrees that the construction certificate was printed by administration staff on Mr Cohen's instructions. We are satisfied that on 12 September, the same day that Ms Everson sent the facsimile to Mr Finianos, she, or someone else in the office, printed out the construction certificate on Mr Cohen's instructions. In relation to the date on the construction certificate, 12 September 2000, Mr Cohen agreed that the accredited certifier handling the file would ask the clerical staff to print the construction certificate when it was ready to be issued. As we have said, the certificate named Mr Cohen as the accredited certifier and bore the date of "12/Sep/2000". That date was generated by the computer when the certificate was printed. The attachments to the construction certificate bore Mr Cohen's stamp which stated, "This is the plan/spec referred to in Essential Certifiers Certificate dated . . . . .Cert. No. . . . . Officer B Cohen Accreditation No 623." One of the administration staff would have stamped the attachments using Mr Cohen's stamp and filled in the remaining details. We accept that it was the company's practice for the date stamped on the annexures to be the same date as the date on the construction certificate. That was the situation for the construction certificate in dispute in these proceedings.
37 Issuing of the construction certificate. On 20 September 2000 the architect, Mr Drummond, informed the builders of the outstanding issues that were delaying the issuing of the construction certificate. On 22 September the builder, Ray Finianos, sent a facsimile to Ms Everson with 'all remaining documents required for the release of the construction certificate.' The construction certificate was issued (released to the builder) on 26 September 2000.
38 Practice in the office. Ms Everson's evidence was that it was the practice when a certifier was absent from the office, and the matter was urgent, for another certifier to sign a construction certificate on his behalf. She said that she would provide the available certifier with the file when advising them of the request. Mr Cohen denies giving Mr O'Brien any authority to sign a construction certificate on his behalf. He said there was no practice that another accredited certifier would sign a construction certificate if the person handling the file was not available and was not aware of that ever having happened. The practice when Mr Cohen worked at Council was that other builders would sign off, because Council was the issuing authority. However Mr Cohen denies that in 2000, he thought the company, rather than the individual certifier, was the certifying authority. That answer is not consistent with the fact that Accredited Certifiers was named on the certificate as the certifying authority. Mr Cohen says that the only reason he became the PCA was because his name was on the construction certificate. Mr Cohen denies that the matter became pressing while he was on leave. When asked why he sent the fax of 1 September, he said it may have been because the client was pressing for the construction certificate. He agreed that sometimes clients need the construction certificate urgently.
39 Mr O'Brien said it was not a common practice in the profession for one accredited certifier to sign for another, however, if the construction certificate was ready to be issued and the accredited certifier was not available, someone else could sign. He said he had signed for other accredited certifier's before, but he can't remember the details.
40 Finding. Despite Mr Cohen's denials, the fact that Accredited Certifiers was named on the certificate as the certifying authority satisfies us that both Mr Cohen and Mr O'Brien wrongly assumed that the company was, in substance, the certifier and that any of the three accredited certifiers who were directors of the company could sign the construction certificate. While the file in relation to the Northmead project was not in evidence, the documentation that was in evidence reveals that Mr O'Brien did not initiate any correspondence with the builder or architects, nor did he sign any correspondence prepared by Ms Everson. The only place his name appears in any of the documentation is on the certificate itself. This leads us to infer that Ms Everson was the person who attended to the necessary detail and it was she who asked Mr O'Brien to endorse the certificate. We are also satisfied, in accordance with the evidence of Ms Everson and Mr O'Brien, that the practice in the office was for another certifier to sign on behalf of the person whose name was on the certificate if the matter was urgent.
