She said it was worrying that where the abuse of power “seems absolutely rampant” and the country had been “devastated over eight weeks”, parliament had not taken action to assert its oversight role.
She stressed that her concerns related to the conduct of all political parties, not only of the government.
Richards said she hoped that lawyers would write more in the public domain on “pressing questions”.
She said she and lawyer Nazeer Cassim chose to write to the presidency in April after attempting to prompt political parties and civil society organisations to take a public stand on the constitutionality of the command council and its lockdown decision-making.
“Only when that failed and we became concerned that that debate was dead did we decide to write the letter. We wanted to reinvigorate the debate,” she said.
The IRR said it was imperative for President Cyril Ramaphosa to end his government’s abuse of power and of the constitution.
"If President Ramaphosa does not do this, the people of South Africa will do it for him,” said Pretorius.
