Applying the points you pointed can in some way help your attempts at seeking dismissal of the FIR/charge sheet under Section 482 of the CrPC. Here's how-
1. Vague Allegations: If the allegations are general and lack specific instances of harassment, it can be argued that the FIR is based on vague and unsubstantiated claims, which can be grounds for quashing.
2. Two Police Complaints on the Same Date: Highlighting that two complaints were filed on the same date with the same CSR number, and one was used to file the FIR after the dowry prohibition officer's report cleared you, can indicate a possible fabrication or misuse of legal provisions. This discrepancy can be critical in showing inconsistencies and mala fide intentions.
3. RCR Filing: The fact that your wife has filed a Restitution of Conjugal Rights (RCR) case asking you to live with her can be used to show that she has contradictory intentions. It is unusual for someone to seek reconciliation while simultaneously pursuing criminal charges under Section 498A, which can be portrayed as a strategy to pressurise you.
4. Detention without 41A Notice: Being detained without prior notice under Section 41A CrPC and then being asked to sign it retrospectively can be a significant procedural violation. This point can highlight police misconduct and procedural lapses, strengthening your case for quashing the FIR.
