The girls, aged two, four and eight, were brought to a hospital by their mother and a friend on Tuesday and the hospital authorities informed police about their deaths.
The DCW in the report has sought details of the circumstances that led to the deaths and the health status of the parents.
In its notice to the police, the women's panel has asked for a copy of the initial post-mortem report and has sought to know the status of the probe.
"The incident is extremely shocking and tragic. The commission has instituted an inquiry into the matter," the DCW said in its notice.
The girls died due to "malnourishment/starvation and its complications", according to the initial post-mortem report,.
Police had said a forensic team inspected the place where the family was staying and found some medicine bottles and pills for treating loose motion.
The girls' father, a casual labourer, is missing since yesterday, though locals had said he had gone in search of work and would return in a couple of days.
No injury marks were found on the bodies, they said.
Initially, it seemed to be a case of natural death but with the medicine bottles being recovered, police want to ensure that there was no foul play in the death of the girls.
Locals had said the family had moved ito the area on Saturday
Two of the sisters, aged two and four, had been unwell for a few days. They suffered bouts of vomiting and loose motion, they had said.
The girls' mother is not "mentally sound" and told police that she did not know what happened to her daughters and how they died.
