U/s 151 cpc 8 rule 1a in dvc allowed to submit docs?

Hi Experts,

This is in my DVC, my advocate now filed two petitions under order 8 rule 1A and section 151 of cpc

1. To receive additional counter

2. To receive documents which are very to decide the interim mantance/final maintance

The OP filed counter in both the petitions saying

1. Not a correct provision

2. Why didn't we file it at the time of counter

3. No reasooning of delay in submission (the advocate mentioned the reason for only one document)

So is it a correct provision? if not, can we "NOT PRESS" and file a fresh petition? I have changed my advocate so, currently i am about to engage a new lawyer.
