procedure to revoke the irrevocable power of attorney.

attach the POA for my examination or look on your own in it if there is breach of any cindition???????????/

We need to see whether it is for valid considration or how, if there is any breach of any condition or if power is given in concurrent of any other doucment or given only for mere faith. If for consideration cancellation is not so easy but if given only based on fatih then it can be revoked by giving necessary notice and/or newspaper declaration, if donee is not will to come and sign deed of cancellation of power of attorney.

If power is for valid consideration one cannot revovke it unilaterally. In such case detailed study of facts and circumstances is required.  

Safe way is to file a civil suit for cancellation.
