Hi Sneha, I am attaching the annual reports
1. Arvind Chemical - See page No 6 of the report where the Directors have recommended an auditor instead of the retiring auditor due to the fact that the Existing auditor has expressed his unwillingness.
2. Ranbaxy's Annual Report is quite large for upload here, so i am giving you the link
In the Directors Report a similar recommendation have been made
https://www.ranbaxy.com/investorinformation/annual_pr2008.aspx
Based on my intrepretation and these annual reports you can safely conclude that no 225, no special notice. The Board can recommend a name of the auditor. If the Shareholders are not happy with the name, then they can go via special notice.
That is, the initative lies with the Board and not with the shareholder as in the case of not wanting a willing retiring auditor.
Good Luck
Shiva
