The ABC's defence from the now-settled case brought by the former federal attorney-general Christian Porter will not be made public after a Federal Court ruling today.
Mr Porter took action against the ABC over a story about an unnamed cabinet minister accused of an alleged historical sexual assault.
Mr Porter later revealed himself to be the subject of the allegations but denied any wrongdoing. The case was discontinued in May but details of the ABC's defence have remained suppressed.
Mr Porter asked the Federal Court to secure the material from public access, but media organisations include Nine Entertainment and News Corp asked the court to lift the suppressions.
