مسؤولية الوكيل

A POA can be cancelled/revoked by the executor at any time. Since you did not issue it, you have no authority to revoke it.

Your boss should cancel/revoke the POA. You will not face any issue unless you misuse it.

Misuse of the POA is a serious offence and a breach of trust or fraud case can be filed and tried both under criminal and civil procedures in court.

If you used the POA for any financial transaction based on which business was conducted, and if the POA is not valid for any reason whatsoever, you will still be accountable for the period you used.
