Pat, March 19: Former Bihar Chief Minister Rabri Devi and her elder son Tej Pratap Yadav on Monday expressed disappointment over the conviction of RJD leader Lalu Prasad in the fodder scam, saying they had thought he will be acquitted. “I was expecting acquittal. It disappointed us. But we respect the verdict and have faith in judiciary,” Rabri Devi told the media here. Tej Pratap said he expected “relief” for his father. Nonetheless, “we respect the court verdict”. A special CBI court in Ranchi on Monday convicted former Bihar Chief Minister Lalu Prasad in the fourth fodder scam case but acquitted another former Chief Minister Jaganth Mishra. Rashtriya Jata Dal (RJD) spokesperson Shakti Yadav said the party would challenge the verdict in the High Court.
