Both Rabri and Tejashwi reached the court on Thursday morning.
The court had summoned 12 others in the case; including Lalu Yadav; who is currently in jail. The summoned were issued after the charge sheet prepared by the Central Bureau of Investigation.
Lalu and his family have been accused of illegally giving away the railway hotels on lease while he was in power as a Railway Minister.
CBI also got a permission to initiate a case against former IRCTC group manager BK Aggarwal last week.
