Three of the four men charged in relation to the murder of former bikie boss Mahmoud "Mick" Hawi have been committed to stand trial, with prosecutors hoping to try them together in the Supreme Court.

A day after being denied bail in a bid that saw him criticise the Crown case against him as "weak", Ahmad Doudar appeared via audio-visual link in Central Local Court on Thursday to enter a plea of not guilty to the charge of murder.

His co-accused, alleged gunman Yusuf Nazlioglu, also entered a not-guilty plea to murder via audio-visual link, and will face the Supreme Court along with Mr Doudar on June 17.

Moustafa Salami, who is charged with being an accessory after the fact to murder, attended court on bail to plead not guilty.
