Former attorney-general Christian Porter has lost a bid to reduce his costs in a Federal Court action linked to his defamation battle with the ABC.
Mr Porter has settled with the ABC over his claim he was defamed in a story about an unnamed cabinet minister accused of an historical alleged rape.
He strenuously denies the allegation.
In court action that saw Mr Porter’s barrister removed from the case over a conflict of interest, his lawyers argued they should only have to pay 70 per cent of costs because of a late affidavit from the other side.
But the Federal Court has ruled it was not late and he will have to pay the full costs.
More to come.
