“ 8. Unfortunately, it is not possible for the purchaser respondent or the tenant-appellant to give direct testimony about the time of the construction or the nature of the construction vis-a-vis Explanation (b) or (c). The best testimony is the municipal records about the completion of the building and the verification by the municipal authorities as to whether a new construction has come into being or an old construction has been remodelled and, if so, when exactly the completion took effect. The municipal assessment record produced in the court merely state "increased assessment". It may suggest the existence of an assessment which has been increased or it may perhaps be argued that when the building was reconstructed a new assessment was made which was more than the previous assessment and, therefore, was described as increased assessment. The oral evidence in the case, apart from what we have set out, is inconsequential, being second hand testimony. Even the recital in the rent deed that there was a new construction is 1965-66 is by the appellant and the respondent, neither of whom has any direct knowledge about the construction. Of course, an admission by the appellant is evidence against him but an admission is not always conclusive especially in the light of the municipal records such as are available and the burden such as has been laid by the statute.”
