Regarding Process group ID

Hi folks,

I am a learner in Unix. While going through Process group ID, found
that A process can set the process group ID of only itself or any of
its children. Furthermore, it can't change the process group ID of one
of its children after that child has called one of the exec functions.
Not able to understand why?. Can some one explain why this behaviour
is like this?.

Appreciate your help in this regard.

Thanks,
Vikas.
