The angry Newcastle Knights will hold talks with the National Rugby League over "ambiguities" and "anomalies" in the judicial system to ensure there is no repeat of the incident which led to the suspension of Josh Perry.

The Knights had their application for leave to appeal Perry's one week ban for "raking and clawing" Wests Tigers centre Terry Hill rejected by judiciary chairman Greg Woods on Friday morning.

Woods, who heard submissions from Perry's counsel Alan Sullivan QC and judiciary commissioner Jim Hall, said there was "no aspect arising from (Newcastle's application) which gives rise to a possible appeal".

The NRL club reacted by issuing a press release in which football manager Mark Sargent said the Knights held concerns with some aspects of the case and would be taking them up with the NRL.

"Josh's case is certainly an unusual one, but we are satisfied that we have received a fair hearing by the NRL over the last 48 hours" he said.

"Our barrister Alan Sullivan QC has raised, what we consider to be, a number of anomalies in the rules and procedures of the judiciary system," Sargent said.

"We intend to raise a number of those concerns privately with the NRL.

"We will attempt to ensure that some of those ambiguities are addressed, so that the situation which we have seen this week is not repeated".

Perry's suspension drew warnings from high-profile players and officials that the judiciary had opened up a Pandora's box by finding him guilty of raking the face of Hill.

Newcastle coach Michael Hagan conceded the club wasn't happy with Woods' decision, but had to focus on Saturday's game against Melbourne.
