State Human Rights member Mandhata Singh while hearing the complaint of Aranya Devi, directed the minister to submit his reply by August 7 when the matter would be heard next.
The complaint, wife of Ram's domestic help Anandu Paswan, had alleged that her husband was injured by cattle reared by the minister at his official bungalow two years back and was not provided proper treatment.
Sanjay Kumar Bharti, lawyer of Ram, contested the allegation and said treatment was provided to Anandu Paswan and proper care was also taken.
67-year-old Ramai Ram is a veteran politician, eight time MLA from Bochahan (SC) Assembly seat in Muzaffarpur district and is currently the transport minister in the Jitan Ram Manjhi government.
