Need your advice on the below issue.
In one of the civil litigation where the defendant, who is a Promoter/Developer of buildings has claimed legal aid from District Legal Service Authority by showing that his family income is not more than Rs.2000 per month and unfortunately his request has been accorded/granted by the Authority.
The plaintiff has asked the Legal Aid Dept through RTI, to disclose the documents submitted by the Developer/Promotor, based on which, he got the relief. The Legal Aid Dept, provided the information, that the Promoter has submitted a family income certificate which was signed by the local councellor.
The plaintiff wants to file another suit against the Promoter/Developer for this unlawful and malafide act, since the Promoter/Developer has defrauded the government and usurped public money on false pretexts.
Please advise, how should the plaintiff proceed in this context.
