Economic Freedom Fighters spokesperson Mbuyiseni Ndlozi said the EFF application that Parliament "Must institute" impeachment proceedings against Zuma came after the ruling by the Constitutional Court that Zuma broke his oath of office.

"After writing several times to the Speaker of the National Assembly that Zuma must be subjected to a disciplinary hearing to determine if his breach of the oath of office constitutes a "serious" violation of the Constitution, she refused," Ndlozi said on Monday.

"As a result, the EFF instituted an application to the Constitutional Court to determine that the Speaker of the National Assembly should have subjected Zuma to a disciplinary process for violating the Constitution as requested by the EFF."

In March last year, the Constitutional Court delivered a damning ruling in which it stated that Zuma had failed to "Uphold, defend & respect the Constitution" when he did not adhere to the remedial actions called for by former Public Protector Thuli Madonsela.

Madonsela found that Zuma had derived undue benefit from the security upgrade that spiraled to a cost of more than R200-million & eventually included the addition of a swimming pool, cattle kraal & amphitheatre to Zuma's home at taxpayers' cost.
