The alliance will hold processions and rallies across the country on Tuesday and Wednesday, BNP Joint Secretary General Ruhul Kabir Rizvi announced on Monday.
It will also observe the UN's 'International Day of the Victims of Enforced Disappearance' on Aug 30 by forming human chains across the country.
The programmed announcement was made at press briefing at the BNP headquarters in Naya Paltan.
"The Constitution says that the state will ensure an independent judiciary, while the law empowering Parliament to impeach judges is meant to control it. This law will effectively ensure the prime minister's power to supervise the judges," the BNP leader told reporters.
