"BCCI rules clearly state that the Chairman has got the right (to vote), therefore I will take legal remedy," Mahendra told reporters here.
"As far as taking away my right is concerned, I disagree with him. For the last 76 years, this has never happened," the BCCI chief said.
Krishnamurthy's decision pertaining to the President being left only with the casting vote is being seen as a serious setback for the Jagmohan-Dalmiya faction. Dalmiya had last year used all his three votes to pip Union Agriculture Minister Sharad Pawar in a close contest.
"Whatever I understand from the Supreme Court order, he (the observer) will decide about the validity of the votes and eligibility within the framework of BCCI rules," Mahendra added.
