This is after the company sued its lawyers for defamation, claiming R500 000 in damages.
The Cape Town-based human rights law firm said on Friday that MRC, which planned to mine titanium in the rural community of Xolobeni on the Wild Coast, had sued two of its attorneys.
It said Tracey Davies and Christine Reddell, along with a local community activist from the West Coast, Davine Cloete, were sued allegedly for making defamatory statements about its subsidiary company, Mineral Sands Resources (MSR) and its director, Zamile Qunya.
MSR has claimed R250 000 in damages from each of the attorneys, and a further R750 000 from Cloete.
