In a WhatsApp message to mediapersons, Bedi said officers who were invited for the 'Independence Day At Home' but did not turn up without due intimation or permission for exemption should send their explanation within three days to her Secretary.
"Unsatisfactory explanation will lead to placing a written displeasure in the concerned officers' personal file," she said.
The LG said attending a function for which invitation was extended to the officers "is not only part of your (officers) official duty but it is also an expression of respect to the occasion".
She hoped that "in future you (officers) will all respect the sanctity of the official invitations".
