DES Hasler and the Bulldogs are headed for the Supreme Court.

The former coach is suing the club for a breach of contract, with documents filed by lawyers in the Supreme Court on Tuesday, according to Nine News reporter Danny Weidler.

The club’s decision to try to sack Hasler without a payout could end up costing them.

Hasler was punted as coach in September and, according to The Daily Telegraph , his claim is for the full $2.4 million his two-year extension at Canterbury would have been worth.

The two-time premiership winning coach signed a heads of agreement to stay on with the club earlier this year.

Hasler claims the agreement he’d reached with Canterbury, which tied him to the club until 2019 on a deal worth more than $2 million, is a legally binding contract.

However that claim will be fought by the club in court, with Bulldogs chairman Ray Dib confirming in a statement that the matter would be defended.

“This week the club received court documents filed by Des Hasler’s lawyers,” Dib said.

“The club intends to defend the matter. Given that the matter is now before the courts, it is not appropriate for any further comment to be made by the club regarding the dispute.”
