If you have obtained a stay order from the High Court in a criminal case, it generally implies your personal appearance in the trial court is dispensed with. However, you must formally submit a certified copy of this stay order to the trial magistrate. It's also advisable to file a petition under section 205 of the Cr.P.C. to ensure your personal appearance is excused until the quash petition is resolved, preventing any potential Non-Bailable Warrants (NBW).
