Cowan's barrister, Peter Davis, said Mr Carmody had met with Bravehearts founder Hetty Johnson shared an email, in which she referred to him as 'Tim' and included a smiley face. Mr Davis said Bravehearts' interests were contrary to Cowan's, which created the conflict. 'It's not suggested for a moment that Bravehearts is a dubious organisation, however it's a lobby group and Mr Cowan is someone who has been directly targeted by that very lobby group,' Mr Davis said. Mr Carmody denied he had any sort of relationship with Ms Johnson, and said the meeting was standard practice. 'None of these meetings impede my neutrality or impartial discharge of my judicial function,' he said. 'Ms Johnston and I do not have a relevant, close and continuing relationship that would impact on the impartiality of my decisions or processes.' Director of Public Prosecutions Tony Moynihan said the situation was unprecedented and there should be no "next step" until the application is actually filed.
