Adani does not know if Queensland activist it is suing obtained confidential information, lawyers say

Guardian Australia understands Ben Pennings has rejected the company's offer to settle the multimillion-dollar lawsuit

Lawyers for mining giant Adani told a Queensland court they do not know what confidential information - if any" - about the Carmichael coalmine was obtained by the environmental activist Ben Pennings, who is being sued by the company for breach of confidence.

At the centre of Adani's multimillion-dollar damages claim against Pennings is an allegation that he solicited confidential information about the construction process and used it to harass contractors.
