A federal court judge has backed an employer's right to sack outspoken workers as long as it's done to protect an organisation's reputation or business interests, an expert says.
Judge Graeme Hill on Friday threw out concert pianist Jayson Lloyd Gillham's case against the Melbourne Symphony Orchestra, finding he was not unfairly dismissed.
The case centred on Gillham's termination in August 2024 after he told a recital audience that Israel had deliberately targeted some journalists to prevent the reporting of war crimes.
Gillham claimed he was sacked because of his political beliefs but Judge Hill determined that was not the case, rather the MSO was protecting its own business interests and reputation.
Giuseppe Carabetta, an associate professor of workplace and business law at the University of Technology Sydney, said employers would welcome the judge's ruling.
"The key lesson from the Gillham decision is that Australian employers are not being given a licence to punish workers for their political opinions," Dr Carabetta told AAP.
"But what the court has reinforced is that organisations may regulate the use of their platforms, stages, brands and reputations."
Judge Hill noted the orchestra had a policy of not supporting either side of the Gaza conflict and there was a custom of performers not making statements about sensitive political issues.
That finding also provided support for employers who wanted to avoid taking a stance on highly contentious issues, Dr Carabetta said.
"The judgment gives some comfort to organisations seeking to maintain political neutrality, provided they can demonstrate that their actions are genuinely directed to institutional interests rather than suppressing a particular viewpoint," he said.
The judge also supported the MSO's contention that they controlled the stage, rather than the performer, the associate professor said.
"The court seems to accept that performers do not automatically acquire a right to use an employer's or host's platform to make political statements on matters unrelated to the engagement," Dr Carabetta said.
Gillham on Friday said he was disappointed with the judge's decision and he would take some time to consider the ruling before commenting further.
MSO chair Edgar Myer welcomed the findings and said he hoped the orchestra could now focus on the music.
The question of costs will be decided at a later date.
