Musician Mzbel has condemned the Supreme Cout for sentencing a radio presenter and two panellists to four months in jail.
They had reportedly threatened to kill judges after the court ruled that the Electoral Commission should delete the names of 53,000 NHIS cards registrants from the voters register.
In a reaction on Facebook, Mzbel said the court had used "a strong hammer to kill three harmless ants".
She said the judgement will rather cause serious injury to the judiciary, especially the apex court.
"...it will heighten tension and will rather harden miscreants who may have calmed down because of the general atmosphere.The situation at the time the three judges cannot in any way be compared to this vastly improved system with our human right record surging up.
"We now have a well constituted political structure with effective institutions operating without suppression,the authority of the Supreme Court remains intact so why taking our minds back psychologically," she said.
In a letter sent to the president on their behalf by their lawyers, they called on him to exercise his prerogative of mercy on them, according to a report by classfmonline.com.
