Kyle Sandilands has officially kicked off legal proceedings against former employer ARN Media after it ripped up his $100 million contract last week.

Court documents were served on Commonwealth Broadcasting Corporation (CBC), a subsidiary of ARN that holds the licence for KIIS 1065 Sydney and the contract with Sandilands, on Friday.

ARN announced the news in an ASX market update released this morning.

Sandilands’ legal team is arguing that ARN’s claim he committed “serious misconduct” during an on-air bust-up with co-host Jackie O Henderson is untrue.

They argue his termination on the grounds of serious misconduct is therefore invalid.

“They allege that there was no act of serious misconduct or breach of contract, and that the termination was unconscionable under the Australian Consumer Law,” the statement from ARN reads.

“The applicants seek an order for specific performance of two contracts, payment of whatever amounts are due and payable under the contracts at the time of judgment, and damages.”

ARN disputes Sandilands’ claims and said it intends to defend the proceedings.

It could be a costly legal battle, given that there was believed to be more than $80 million still on Sandilands’ 10-year contract.

“Given the early stage of the matter, ARN is unable to reliably estimate the outcome or any potential financial impact,” the statement said.

Sandilands announced his contract with ARN had been terminated last Wednesday.

He said in a statement at the time that he planned to take legal action and alleged that the network wanted a way out of the $100 million deal with him.

“They thought they saw a chance to get out of the contract they signed with me a year ago, and they ran with it,” Sandilands claimed.

Henderson is also reportedly considering legal action after she was taken off air in February.
