Sydney Flames barrister Paul Moorhouse argued the emails fell under legal professional privilege, meaning that they were confidential discussions between lawyers and clients and should not be viewed by third parties.

However, Heal's barrister Glenn Fredericks said the emails did not relate to legal advice but instead concerned the factual findings of the investigation.

Mr Fredericks said that even if the documents were privileged initially, they were not now because prior affidavit evidence given by Mr Smith to the court had revealed previously hidden details about the documents and their contents.

Justice John Halley found some of the emails were indeed confidential, but rejected the team's claims over others, ordering that they be handed over to Heal ahead of a five-day hearing due to commence Friday.

The 52-year-old was suspended as head coach in the Women's National Basketball League in January while an internal investigation into multiple bullying complaints was conducted.

Findings of misconduct were made on February 3, with a show cause notice issued to Heal before his possible dismissal. He denies any wrongdoing.

On February 15, the Flames promised to the Federal Court that they would not terminate Heal's employment until, at soonest, the final day of the hearing.

In return, Heal has promised to pay the Flames compensation for damages which result from this undertaking.

In the Federal Court lawsuit, Heal has accused the Flames of breaches of employment law, and is seeking penalties and employee entitlements such as accrued leave.

Mr Smith and president Victoria Denholm are also alleged to have been involved in the breaches.
