Former Wallabies captain George Gregan and a business partner have been accused of "cooking" and withholding documents relevant to their alleged takeover of a sportswear and equipment business.
Former PTP Fitness managing director Alexander Goldberg claims he was unlawfully dismissed while on carer's leave by fellow co-founder Matthew Dixon and Gregan, a minority shareholder.
"It's part of our case that this was a continuing campaign to get rid of Mr Goldberg," barrister Robert Stitt QC told the Federal Court on Wednesday.
Mr Goldberg, 41, says his June 2019 sacking from the $300,000-a-year job came a month after confronting Gregan about the former Wallabies captain's endorsement of a competitor's product.
Australia's most-capped rugby union international was at the time paid $20,000 per year to endorse PTP Fitness products.
He also owns a fifth of the company with his wife Erica, with Mr Dixon and Mr Goldberg each having 40-per-cent stakes.
Gregan and Mr Dixon deny operating unlawfully, claiming Mr Goldberg stole intellectual property, worked unjustly with rival and related firms and failed to attend board meetings.
The three men shared in dividends totalling $1.24 million between 2015 and 2018, court documents suggest.
The 11-year-old business has since posted operating profits totalling $4.4 million in the past three financial years, Mr Goldberg claims in court papers.
Gregan and Mr Dixon were on Wednesday accused of not properly providing copies of relevant communications ahead of a nine-day trial kicking off on June 15.
The version provided to Mr Goldberg's lawyers was "substantially amended and doctored" and didn't match with the version provided to the court, Mr Stitt said.
"These documents are being - to lapse into the vernacular - cooked," he said.
But Gregan and Mr Dixon's lawyer said several redactions were made on the basis it was considered irrelevant or subject to claims of legal privilege.
Mr Dixon, aged 52 and living on Sydney's northern beaches, had also produced multiple copies of his messages and hadn't cross-checked for consistency, Robert Newlinds SC said.
"Regarding Mr Gregan, I'm not sure and I'd like to get instructions," he said.
Justice John Halley noted an "enormous quantity of texts" peripheral to the case had been produced and the applicants' already had "an embarrassment of riches" before them.
Mr Stitt alleges the communications confirm Gregan and Mr Dixon's "concerted and orchestrated campaign" to remove the Bondi Beach man from the company at no cost to them.
He told an earlier hearing Gregan texted Mr Dixon "he's in for a rude shock" in November 2018.
Later messages to Mr Dixon read "it's ridiculous he's trying to delay the inevitable", referred to a "blitzkrieg" and included a suggestion that Gregan's mother's maiden name translated to "kill first, ask questions later", Mr Stitt said.
The reading of the "salacious extracts" drew a censure from Justice Halley for potential prejudice.
Mr Stitt has also openly accused a lawyer of conspiring in the takeover, alleging neither Gregan nor Mr Dixon was "commercially sophisticated".
"Neither ... had the commercial nous to run the sort of campaign that was run," Mr Stitt said in May.
But Mr Newlinds fired back, saying the claims of conspiracy weren't part of the pleaded case and were being floated under privilege.
"They keep saying things that aren't part of their case," he complained to the court in May.
Another court skirmish is tentatively set down for June 10, ahead of the trial.
It's a second business headache for the Gregans after the Mosman couple placed their coffee shop empire into voluntary administration in March.
