The leaders claimed that the bill would strengthen deprived communities in the country.
"My party is strongly against injustice to anyone," Agrawal said.
"The amendment will strengthen the legislative provisions to protect the people from SC/ST communities," he said.
The BSP holds sway over Dalit pockets in some parts of the central state which has been under the BJP rule since 2003.
RSS Madhya Kshetra Prachar Pramukh Narendra Jain refused to comment on the issue.
Hiralal Trivedi, the convener of the Madhya Pradesh Samanya Pichhada Evam Alpsankhyak Varg Samaj (SAPAKS), said the amendment will create a "social unrest".
He said the government's move should be challenged in the supreme court.
The Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Amendment Bill 2018 rules out any provision for anticipatory bail for a person accused of atrocities against SC/STs, notwithstanding any court order.
It also provides that no preliminary enquiry will be required for registering a criminal case and an arrest under this law would not be subject to any approval.
The move to amend the Bill is being seen by the Opposition as a reach-out by the BJP-led NDA government to Dalits, ahead of their proposed nationwide protest later this month to demand restoration of the provisions of the law which, the Dalit groups allege, were diluted by a Supreme Court ruling of March 20.
