Please find my questions as below:
1) Can the quash order issued by High Court protect me from arrest?
Since the high court has already disposed the quash petition in the manner as described in your query, there is no protection to you from being arrested even if the procedures under the said provisions of law is followed by the police.
2) Can I join back my job as I am on vacation now(loss of pay) and since, the police has served CrPC 41a notice to my manager, will it enforce me to respond back to police notice once I rejoin my job?
The employment has nothing to do with this police complaint. Your manager cannot refuse you to join the office after vacation for this matrimonial dispute.
3) Police haven't got any written signed copy of their notice neither from me nor from anyone else.Can they still claim that they have served me the notice?
If police are not able to serve you the notice then they may procure a warrant from court to arrest you since you will be termed as absconding or gone underground.
4) What are the chances of getting the AB, if they claim that they have served me the notice? They have post-poned "the hearing on AB", a couple of times by not submitting the official FIR copy to the session court and court has warned them to submit the copy without any delay and finally they have submitted the copy on last Thursday. But, they are claiming that they have served me the notice and my advocate argued that it hasn't been served. Hearing is post-poned to some other date.
It depends on the proofs and merits, however since there is a legal action pending, your anticipatory bail application deserves merit.
5) Can I withdraw my bail petition in sessions court as there seems to be no time limit in disposing the petition and can file a new AB petition in High Court?
There is no legal impediment in it but ensure that you dont fall into the fire directly while jumping out of frying pan.
6) Any advice in this regards would be really helpful.
