Dear Mr Sharma,
A second petition for quashing of proceedings under section 482 CrPC is not maintainable. Unless a liberty was given by the High Court to approach again at the time of withdrawal of the first 482 petition.
Even otherwise, the High Court is a hesitant in invoking its inherent jurisdiction and quash the proceedings after the trial has begun. You mentioned that you have obtained certain key documents which is relevant for your case now. You may use those documents at the stage of defence witnesses and then argue for acquittal.
Regards,
