Legal notice limitation

Respected Experts,
My consumer case filed in state forum is still pending. I have sent a legal notice in 2018 to the same opponent, asking them to furnish
the copies of the sanctioned plan, planning permission, building permit, affidavit, indemnity and the documents enclosed for the purpose of obtaining the planning permission. Is the legal notice valid to file a case in magistrate court or writ? If not, can I send the same notice again with current date? If Yes, whether any time validity for legal notice. The opponent firm / Director have not replied to the notice instead the filed three police complaint and one of the complaint had been registered as FIR and ultimately the FIR was closed with remarks "Mistake of Facts" removed from online list. Thank You
