“Para-11. Sub-rule (3) of Rule 1A of Order VIII permits the documents to be received only on leave being granted by the Court. Grant of leave is not for the mere asking, nor is the Court a mere Post-Office to receive documents even in the absence of any reasons being furnished for failure to file the said documents along with the written statement. Admittedly, in the case on hand, no reasons whatsoever have been furnished by the petitioner, let alone adequate cause been shown as to why the documents, which were the subject matter of the application, could not be filed earlier along with the written statement. Having chosen not to give any reasons, it is not open to the petitioner to contend that the Court below should have received the documents, since the petitioner's right could be adversely affected for failure on its part to receive the documents. While it is no doubt true that admissibility and proof of documents are matters which ought not to be gone into at the time of receipt of documents, the fact, however, remains that the leave sought for can only be granted on adequate reasons being furnished justifying failure on the part of the applicant in not filing the documents along with the written statement earlier.”
