Justices P K Jaiswal and J K Jain of the HC's Indore bench, however, acquitted another accused in the judgement passed yesterday.
The trial court had on September 13, 2013, sentenced Tarun Soni, Dilip Sharma and Rajkumar Kushwaha to death. All three worked for a private bus operator. Soni was a driver, Sharma a conductor and Kushwaha a cleaner.
The trial court had also sentenced bus owner Naresh Kumar Doshi to life sentence but the High Court acquitted him.
The convicts poured petrol on the other bus, which had passengers onboard, and set it on fire. Fifteen people were killed and 19 people suffered injuries in the incident.
