Former Defence Minister Dominic Nitiwul has questioned John Dramani Mahama's government's moral right to arrest their political opponents after discontinuing corruption-related cases.

The Attorney General and Minister of Justice have discontinued several cases since the National Democratic Congress (NDC) took over power.

These cases involved former appointees of John Dramani Mahama during his first term as President of Ghana.

Although there are calls from analysts and corruption fighters for reasons to be provided to justify the decision to discontinue the cases, none have been provided by the government.
