"A good decision has come today," BJP's National Secretary Shrikant Sharma said.
Party's Rajya Sabha member Subramanian Swamy said the court's order has vindicated Yeddyurappa's stand.
Yeddyurappa had always held he was framed to tarnish his reputation, he said.
A special CBI court in Bengaluru today acquitted Yeddyurappa, his two sons, son-in-law and nine others in a corruption case, giving a boost to the political fortunes of the BJP leader ahead of 2018 Assembly polls.
