Criminal cases cannot be withdrawn as such by the complainant.  There are two categories of cases - compoundable and non-compoundable. the former can be withdrawn at the instance of the complainant but not the latter.  In respect of non-compoundable offences, even trial court also cannot quash the case during trial stage and only High Court Under Section 482 cr.p.c. has got the right to quash the FIR and criminal proceedings during the pendency of the trial, only if substantial cause is shown to it.  If your case pertains to matrimonial dispute, i.e., Section 498-A, then both the husband and wife can approach the High Court for withdrawal of case and after satisfying itself about the genuineness of the statement of the wife, the court may permit her to do so and quash the criminal court proceedings lying in the trial court.
