The ABC has doubled down on its defence of the Four Corners article at the centre of a now-defunct defamation case brought by Christian Porter, with the public broadcaster stating it does not regret its reporting and stands by the story. The former attorney general on Monday dropped his high-stakes defamation bid against the ABC, holding a press conference in which he sought to claim he had forced the broadcaster to back down, despite not securing an apology or retraction. Far from ending hostilities between the parties, the deal to drop the case has sparked a fierce war of words between Porter, the ABC and the Four Corners journalist Louise Milligan, who broke the original story. After the ABC agreed to add an editor’s note on its story saying it “regretted” that some readers had “misinterpreted” the article “as an accusation of guilt against Mr Porter”, the former attorney general insisted the public broadcaster had been forced into a “humiliating backdown” and had admitted to regretting the “sensationalist” article. But the ABC hit back, saying it “has not said that it regrets the article” and “stands by the importance of the article”.
