“We are quite clear that sub-section (2) of Section 83 has reference not to a document which is produced as evidence of the averments of the election petition but to averments of the election petition which are put, not in the election petition but in the accompanying schedules or annexures. We can give quite a number of examples from which it would be apparent that many of the averments of the election petition are capable of being put as schedules or annexures. For example, the details of the corrupt practice there in the former days used to be set out separately in the schedules and which may, in some cases, be so done even after the amendment of the present law. Similarly, details of the averments too compendious for being included in the election petition may be set out in the schedules or annexures to the election petition. The law then requires that even though they are outside the election petition, they must be signed and verified, but such annexures or schedules are then treated as integrated with the election petition and copies of them must be served on the respondent if the requirement regarding service of the election petition is to be wholly complied with. But what we have said here does not apply to documents which are merely evidence in the case but which for reasons of clarity and to lend force to the petition are not kept back but produced or filed with the election petitions. They are in no sense an integral part of the averments of the petition but are only evidence of those averments and in proof thereof.”
