Saraki has been battling various legal cases since becoming Senate President, chief among which were charges of false assets declaration at the Code of Conduct Tribunal (CCT).
He was eventually acquitted by the CCT but the Federal Government filed an appeal, in what came as a surprising move to many.
However, the Supreme Court, on Friday, finally decided the case by dismissing all charges brought against Saraki.
Buhari, in a series of tweet posted on his official twitter handle on Saturday, said:
“Senate President @bukolasaraki has persevered through what has no doubt been a tortuous judicial process. In the end, he has established his innocence; the highest court of the land, the Supreme Court, says he is not guilty as charged.
“This is exactly what I did in the three elections in which I contested, before 2015. I was cheated, and I went to court each time, a firm believer in the primacy of the rule of law. The fourth time, God made it possible for me to be victorious and emerge as President of Nigeria.
“Regardless of the challenges the Nigerian judiciary is currently facing, it is one of the cornerstones of our democracy, and no one should be allowed to undermine it. The Supreme Court has spoken, and our democracy is stronger for it.”
