Gillham argues that the MSO’s actions constitute direct discrimination based on political belief or activity, violating his human and workplace rights protected by the Equal Opportunity Act 2010 (Victoria) and Fair Work Act 2009 (Commonwealth). He is represented by Michael Bradley of Marque Lawyers and Sheryn Omeri KC.

The Melbourne Symphony Orchestra released a statement confirming it had been served with a statement of claim by Gillham commencing proceedings in the Federal Court.

“The Melbourne Symphony Orchestra is reviewing the court documents and will respond at the appropriate time,” it said.

Days after the Gillham incident, the musicians in the Melbourne Symphony Orchestra sent a vote of no confidence to the board, requesting the removal of managing director Sophie Galaise and chief operating officer Guy Ross, and asking for an independent review into what had happened.

Within weeks, Galaise was sacked. She has told The Australian she is also considering legal action against the orchestra. Richard Wigley, a musician originally from New Zealand, has been made interim chief executive.

Former federal arts minister and lead singer of Midnight Oil Peter Garrett has been appointed to lead the review, which the orchestra says will “evaluate MSO’s policies, procedures and processes, and cover protocols around freedom of speech and artistic expression on stage”.

More to come.
