Zuma's Nkandla bill

The amount that President Jacob Zuma must pay back for non-security upgrades to his private homestead in Nkandla will be made known to the Constitutional Court on Tuesday.

Treasury confirmed today that it would meet the deadline of June 28 as set by the Constitutional Court.

In its ruling on 31 March confirming that the Public Protector's findings were binding and could not be second-guessed and could only be challenged on legal review, the Constitutional Court tasked Treasury to calculate the "reasonable costs" of non-security upgrades that were implemented by the Department of Public Works.

The upgrades that were identified from the R246 million upgrades were the visitors' centre, amphitheatre, cattle kraal, chicken run and swimming pool.

This was in line with the findings of Public Protector Thuli Madonsela in her report - Secure in Comfort - which was released more than two years ago and which has been the subject of a protracted dispute and controversy.

The court gave Treasury 60 days to determine the calculation and ordered that the "president must personally pay the amount … within 45 days".

The director-general Lungisa Fuzile was reported to be leading the calculation process.

Responding to a query tonight, Treasury spokesperson Phumza Macanda said: "The National Treasury will submit the report to the Constitutional Court on Tuesday, 28 June 2016, in accordance with the requirements of the Court."

A detailed account of the work that had been undertaken, including the methodology followed, would be made public at an appropriate time, said Treasury in an earlier statement.
