Application u/s 311 crpc

Thanks for your response Om Prakash Ji.

I will definitely object the application. However, I wanted to know if it is legally allowed to submit evidence of an incident which occured after registration of the FIR. Shouldn't it be brought to court after registering a new FIR and subsequent investigation?

Also, can someone submit application for new evidence (for an incident which occured after FIR) without first sbmitting evidence for allegations already made in the FIR? 

To me this is clearly a tactic to delay and prolong the case.

Thanks for the clarification Om Prakash Ji.

In my case, the evidence has not even started since the compalinant has not appeared in court for 6 months (2 hearings) after the charges were framed.

However, now instead of coming forward to submit evidence on his complaint, the complainant is asking court permission to accept evidence of an incident which happened after registration of FIR.

I will object to this as a delaying tactic. Let us see how the court responds.
