All the 32 accused in the 1992 Babri Masjid demolition case were acquitted by CBI judge Surendra Kumar Yadav as he read out the 2,000-page order on Wednesday.
Among those acquitted includes former home minister Lal Krishna Advani.
The court observed that the demolition was not pre-planned and evidence against the accused were not strong.
While Sadhvi Ritambhara, Sakshi Maharaj, Vinay Katiyar and Champat Rai Bansal were present in court, three key accused BJP leaders skipped physical hearing and attended through video-conferencing.
Uma Bharti was absent as she had tested positive for COVID-19, while LK Advani and Murli Manohar Joshi had excused themselves on grounds of health and age.
Had they were convicted then they would have faced maximum imprisonment up to five years.
A high alert was sounded in Uttar Pradesh and policemen in civil clothes were on guard in Ayodhya.
2,000 cops were deployed at the building that houses the “Ayodhya Prakaran Court” in the Old High Court building in Lucknow’s Kaiserbagh.
