Amber Harrison has abandoned her court battle with with Seven West Media just days before the sensational case was scheduled to go to court.

The case was slated for a three-day hearing that would have started on Monday.

Seven had been seeking a permanent order restraining her from speaking publicly about the company.

But in a surprise move the former mistress of Seven boss Tim Worner agreed to a permanent gag order preventing her from speaking about the affair.

The former Network Seven employee took to social media on Friday afternoon to announce she’d chosen not to continue the court battle.

Earlier in the day Ms Harrison tweeted an apology to other women whose names were mentioned in the long-running and acrimonious dispute.

In an apparent reference to other employees she alleged had affairs with Mr Worner, Ms Harrison tweeted: “I publicly apologise to the women for their names being made public. This was an apology I was always willing to make.”

Ms Harrison told Fairfax Media that the “hard battle” had left her “financially, physically and emotionally exhausted”.

The decision to concede the demand for a gag order disappointed court-watchers who had been anticipating what a lawyer for Seven described in March as “scurrilous and scandalous material”.

Counsel for Seven, Sandy Dawson SC, told Justice John Sackar a court filing from Ms Harrison was a risk to his client.

“We have had some bitter experience,” Mr Dawson told the court.

Ms Harrison reportedly has also dropped a claim against Seven in the Federal Court in Melbourne in which she alleged the company had breached the Fair Work Act by prejudicing her workplace rights and engaging in adverse action.
