Dear Subodh,
So far I have not come
across any statutory provisions directly related to this. I hope you might have
already checked the provisions related to mergers, acquisitions, takeovers etc.
I request our eParivariyans to help, if any one is
having any idea regarding this.
For the sake of arguments, you make take a stand that,
it is just a practice and not mandatory. However, unless you beat the
logic by your counter logic, the argument may not stand. Please take
care.
Regards,
Dattatri
