Christian Porter's barrister should not have had to step down from acting for him in a defamation lawsuit against the ABC because of ill will felt by the friend of his accuser, a court has been told.
The former attorney-general is appealing the disqualification of barrister Sue Chrysanthou SC and around $500,000 in potential costs after losing a legal battle against a friend of the woman who alleged she was raped by Mr Porter in 1988.
