Wests Tigers halfback Robert Lui has had assault charges dismissed in a Sydney court.

Lui appeared in Burwood Local Court on Wednesday after he had been charged with nine offences in September last year.

They related to his then pregnant partner Taleah Rae Backo, who he has since reunited with.

Magistrate Caleb Franklin dismissed all of the charges.

Lui was stood down by the Tigers late last year before returning to pre-season training and is currently sidelined with an ankle injury.

"Today's court decision brings a welcome end to a difficult period for Robert and his partner Taleah," Tigers chief executive Stephen Humphreys said in a statement.

"They can now continue to build their life together along with their recently born son, Matthias.

"They would also like to thank all of their family and friends for the support they've received."
