False POSH & Negative BGV

Respected Learned Counsels

My Cousin who was working in a Private Bank was accused of POSH Allegation ( Inappropriate touch ) while they were on a visit to client on same bike.

The Complainant lodged false POSH Complaint with Branch Manager against my Cousin two days after the alleged Incident.

ICC was setup to inquire into the matter , Checked the phones too of my cousin & after Investigation they found nothing & no evidence that could have held him guilty.

But the Girl was threatening to lodge false SC/ST case & Criminal Case against my Cousin & threatened the members of ICC too about it.

So despite of lacking any evidence against my Cousin ,ICC asked my cousin to resign & assured that they will leave him with a good feedback & one month pay.

My Cousin resigned in fear & got a job in another bank on his experience.

Now his previous employer wrote negative BGV & is refusing to provide any Reason for citing so remarks in the BGV report.

Now his New Employer is asking repeatedly from his Previous employer about the reasons for the same to which they are repeatedly denying.

His New Job is also in Danger,
He is treated like a Guilty person even after being Innocent.

Please Suggest Some Legal remedies which he can take.

I shall be highly obliged to you all.

Thankyou.
