The petition said that in 2009, Rana was convicted in another case relating to the animal husbandry department and was sentenced to undergo sentence of five years.
The RJD chief further contended that another convict - the then minister for animal husbandry - who was given a three year sentence was granted bail by the trial court itself.
"The petitioner (Lalu Prasad) has been treated differently in the matter of grant of bail in as much as some of the co-accused, who are similarly situated, have been granted bail," he said in his petition.
