The apex court ruled that the Bihar government has no authority to appeal against Lalu's acquittal in the disproportionate assets case probed by the CBI.
A bench comprising Chief Justice K G Balakrishnan and Justices R M Lodha and B S Chauhan said, "Bihar Government is not a competent authority to file an appeal in the case."
Speaking to reporters, Lalu said, "Finally, I have received justice. We welcome the Supreme Court"s decision and have full faith in the judiciary. Whatever decision has been taken, I am sure it is in accordance to the law."
Earlier, Patna High Court admitted the appeal filed by the Bihar Government against their acquittal by a special CBI court.
Both Lalu and Rabri Devi have served as chief ministers of Bihar. They were accused of accumulating wealth beyond their declared sources of income.
The CBI investigated the case against them, but failed, in 2006, to prove them guilty. So a special CBI court acquitted Lalu and his wife.
