'Public in the dark over National Key Points'
R2K says it's in the interest of the public to know where all National Key Points are.
On Thursday, the High Court in Johannesburg reserved judgment in a case between the state and the campaign.
They were arguing whether a list of 200 names under the National Key Points Act must be disclosed.
The state says if the list is made public, it will compromise the country's security.
But the R2K's Murray Hunter says it's in the interest of the public to know where these areas are.
"The Constitution will always look at the balance between secrecy and access to information and almost always rules in the favour of access to information. Many of the National Key Points are actually publicly known."
In 2012, police refused to release a list of sites protected by the Act, citing security concerns.
But R2K says government has recently used the Act to shield state entities like the South African Broadcasting Corporation (SABC) and Eskom from protest and criticism.
