Dear Neha,
The solution to the problem given by me was based on the idea that the Appointmet is against the provision of law. you cannot induct the person as Director in Board meeting.He must necessarily be appointed as a Additional Director as Section 260 applies to all Companies. In order to comply with the law, i recommended resignation followed by appointment as Additional Director in Board Meeting or as Director IN EOGM.
There are chances the resolution for the appointment may be given to any authorities for any purpos.
