The soap opera surrounding Craig Bellamy's scathing attack on the NRL judiciary looks headed for the courts after the Melbourne coach refused to back down on his arrival in Sydney.

Bellamy knocked back the opportunity to apologise for his remarks, in which he questioned the integrity of the judiciary over the two-match suspension imposed on Storm skipper Cameron Smith.

The premiership-winning mentor said he had no regrets as he turned his attention to Sunday's grand final clash with Manly, a match Smith will miss due to the ban.

Judiciary panel member Darrell Williams threatened legal action if no apology was forthcoming - the former Manly centre claiming his reputation had been tarnished by Bellamy's comments.

But Bellamy was in no mood for apologies on Wednesday.

"I had my say last week and it has been pretty smooth sailing as far as we go," Bellamy said as the Storm arrived in Sydney to set up camp ahead of Sunday's decider.

"I said what I needed to say ... I probably didn't express it as well as I'd like to but it was a bit of frustration building up.

"It's over as far as I'm concerned now and we're worrying about Sunday."

Asked if he had any regrets over the situation, Bellamy simply said: "No."

NRL chief executive David Gallop has set up a meeting with Williams and fellow panel members Royce Ayliffe and Darren Britt for Thursday, but it remains unclear whether he will recommend the trio take legal action.

Gallop did, however, make it abundantly clear that an immediate resolution to the matter lay in the hands of the Storm.

"I'm due to meet with the judiciary panel tomorrow, certainly if a full apology was forthcoming that would be entirely appropriate - and the sooner the better," Gallop said.

Asked if legal proceedings were inevitable, he said: "Not necessarily, we're waiting to get some further advice from Melbourne about their next step but of course we all would like to avoid litigation."

Match review commissioner Greg McCallum said the integrity of the game's judicial process had to be upheld.

The former grand final referee did not escape unscathed from Bellamy's spray with the Storm boss and Smith both questioning why players from other NRL teams had not been charged over similar grapple tackles to the one which led to the Test rake being rubbed out.

"There are people within the system at the moment that are hurting from those accusations," McCallum told reporters.

"Reputation is everything in this game and when people attack your credibility and integrity, that's when there is a problem."

The furore over Smith's ban has taken much of the focus off the players involved in grand final week, with their last public appearance to be at Thursday morning's traditional grand final breakfast.

The players attended a fan day at Sydney's Luna Park on Wednesday afternoon with Melbourne star Greg Inglis showing no ill-effects from the knee injury which supposedly had him in doubt for the decider.

Bellamy was left stunned by reports earlier this week with claims that Inglis was only an 80 per cent chance of taking on the Sea Eagles. The Storm coach was adamant the reigning Clive Churchill medallist was in no doubt to take his place.

"Someone told me that on Tuesday and I nearly fell off my chair ... I thought I'd missed something," Bellamy said of the reports.

"Obviously he's got a bit of a problem with his knees but I think he's pretty much 100 per cent sure of playing."
