Dalam memberi tafsiran kepada makna bankers’ book dan menjawab sama ada dokumen-dokumen yang dipohon oleh plaintif terangkum dalam maksud di bawah Akta Jurubank (Keterangan) 1949, Mahkamah ini sekali lagi merujuk tafsiran oleh Mahkamah Persekutuan dalam Protasco Berhad v Tey Por Yee & Anor and other appeals (supra) – [133] Having given the submission and authorities cited by learned counsel for both parties my deepest consideration, I am persuaded that the definition of ‘banker’s book’ under the Act must be given a purposive interpretation and that it is to be done with an updating approach as outlined earlier but in so doing I would still and must confine the meaning of ‘other books’ with ‘ledger, day book, cash book and account book’. So it cannot be just any documents in the bank’s possession which comes within that definition although, as I had said earlier, those very same documents produced or kept by the bank in accordance with advancement in technology such as computers and other forms of information technology should qualify. In other words, as rightly submitted by learned counsel for the respondents, ‘other books’ should be considered ejusdem generis.
