Hi, My friend has completed 2 years 8 months of his article ship period and due to some dispute with his principle, he got transfer from his principle and the 109 form is send to institute by the principle without any reason & reason proof documents as per institute guidelines. but he didn't get his transfer letter yet, So he want to compromise with his principle and rejoin and continue his article ship. is this is possible? what is the procedure for this to happen?
