Amber Harrison's planned counter claim against the Seven West Media could contain "scurrilous and scandalous material", the NSW Supreme Court has been told.
Counsel for Seven Sandy Dawson SC told Justice John Sackar that a court filing from Ms Harrison the night before the next hearing in two weeks time was a risk to his client.
"We have had some bitter experience," Mr Dawson told Justice Sackar.
Amber Harrison - one time mistress of Seven West chief executive Tim Worner - has been silenced with an interim injunction won by Seven which prevents her from leaking more confidential documents.
While agreeing to expedite the case to a hearing, Justice Sackar said he was reluctant to suppress the details of Ms Harrison's counter claim against Seven.
"This is not a censorship issue. I am not going to sit here as a censor," Justice Sackar told Mr Dawson.
However, Justice Sackar reminded counsel for both Seven and Ms Harrison not to breach privilege or the terms of the interim injunction in place against Ms Harrison.
Amber Harrison's cross claim will be heard on March 17 with a four day hearing set down from July 10.
Justice Sackar said he hoped Seven and Ms Harrison would use the time to explore mediation while saying he would not impose it until all efforts had been exhausted.
