The charged supporters gathered in front of the National Democratic Congress headquarters in Accra to pressure home their demand for the release of the trio who sentenced to four month imprisonment by the Supreme Court on Wednesday.
Article 72(1) of the 1992 constitution says that the President may in consultation with the Council of State grant a person convicted of an offence a pardon either free or subject to lawful conditions.
The charged supporters gathered in front of the National Democratic Congress headquarters in Accra to press home their demand for the release of the trio who were sentenced to four month imprisonment by the Supreme Court on Wednesday.
They were cited for contempt by the Supreme Court after they had threatened to harm the judges who sat on the case challenging the suitability of the voters' register by Abu Ramadan and Garry Nimako.
Lawyers for the jailed trio say their clients have instructed them to plead with president Mahama for a presidential pardon.
"Our clients have directed us in circumstances to petition His Excellency the President of the Republic to exercise his powers of prerogative of mercy under Article 72 of the Constitution of Ghana,” George Loh and Nana Ato Dadzie said in a statement.
"We do admit some of the statements uttered by some of our clients are unacceptable. We nevertheless consider custodial sentence of four months imposed by the Supreme Court as being excessive and harsh," the statement added.
