Furious Cronulla coach Chris Anderson has accused the National Rugby League judiciary of "double standards" after fullback David Peachey was suspended for two weeks on a grade three contrary conduct charge.

Anderson also predicted the verdict would give referees a licence to be "prima donnas".

Sharks chief executive Steve Rogers said it was unlikely the club would appeal the decision, which blemished the otherwise clean record of Peachey over a 10-year career and prematurely ended his season.

Cronulla has only two matches left - against Souths at Aussie Stadium on Saturday before hosting the Bulldogs on September 6.

Anderson said he was "flabbergasted" the judiciary had questioned Peachey's integrity by finding him guilty of the grade three charge, which the Sharks tried to get downgraded to a grade one offence.

"I still cannot believe how they can come up with a verdict like that," said Anderson.

"They take a bloke who's done as much for rugby league as David Peachey and question his integrity. I thought it was very poor."

Anderson pointed to Hall's failure to cite any player involved in a wild brawl in a Brisbane-NZ Warriors match on Sunday as proof of the judiciary's double standards.

"I don't think it's done the judiciary any favours," he said.

"It shows up poorly by them, it shows up poorly for Jim Hall to be bringing this case in front of it (the judiciary) for what he did with the Brisbane/Warriors case.
