Well, Wait at least till final CS.
Quashing with speedy trial is filed by a very few number of honest lawyers only (tense to zero ).
Rest of them simply confuses, extorts prolongates by granting a stay order and/or not entering the case in the cause list. Therefore, If you don't go in-person then you should strict with speedy trial with them.
Quashing is possible if there is strong legal grounds (Analyzing whether the prima-facies falls under the definition of crime of the said IPC or not) and strong circumstantial evidences that proves impossibility of committing crime (Using evidence act) only.
Otherwise, HC will not quash since despite of your submissions it can’t be a bar to adduce evidence to forfeit the allegation of complainant.
Therefore, it is always advisable to keep a 2nd prayer of speedy trial since lengthy trial deprives personal liberty as per Article 21 of Indian Constitution so as per section 21 (B) of Hindu Marriage Act pray for order/direction to the trial court to dispose of the trial within 6 months from the communication of the order.
The major advantage of quashing with speedy trial is - your submissions, grounds and evidences will be recorded in the HC order along with speedy trial order which will act as a strong set of evidence in the trial court. This will help because a lot of cheating happens in trial courts. Sometimes, I have seen people wrongly get convicted in trial court and then get acquittal from session courts and/or HC. These are nothing but money extorting plan.
Lastly, I would like to say that, argue properly and to-the-point with no redundancy and fear. Please also don’t expect any sympathy from the judge. Always keep in mind that you need to defeat that judge and the public prosecutor with your to-the-point arguments only.
