TV presenter McIntyre lost his job over five tweets he posted about Australia’s involvement in numerous wars.

Law firm Maurice Blackburn has today filed discrimination claim on behalf of McIntyre.

SBS described the tweets about the Anzacs as “highly inappropriate and disrespectful comments”.

“The case is not about whether Mr McIntyre’s opinions are correct or not. It will focus on whether the views expressed by Mr McIntyre constituted political opinion and whether SBS terminated his employment for expressing these views,” the firm said in a statement.

McIntyre’s comments drew criticism from Communications Minister Malcolm Turnbull, who labelled his comments “despicable” on Twitter.

At the time of the scandal, SBS Managing Director Michael Ebeid and Director of Sport Ken Shipp said McIntyre had breached the station’s Code of Conduct and social media policy.

“Respect for Australian audiences is paramount at SBS,” Mr Ebeid and Mr Shipp said in a statement.

“Late on Anzac Day, sports presenter Scott McIntyre made highly inappropriate and disrespectful comments via his Twitter account which have caused his on-air position at SBS to become untenable.

“Mr McIntyre’s actions have breached the SBS Code of Conduct and social media policy and as a result, SBS has taken decisive action to terminate Mr McIntyre’s position at SBS, with immediate effect.

“At SBS, employees on and off air are encouraged to participate in social media, however maintaining the integrity of the network and audience trust is vital. It is unfortunate that on this very important occasion, Mr McIntyre’s comments have compromised both.

“SBS apologises for any offence or harm caused by Mr McIntyre’s comments which in no way reflect the views of the network. SBS supports our Anzacs and has devoted unprecedented resources to coverage of the 100th anniversary of the Gallipoli landings.”
