Cooke helped keep Hull KR in Super League last season

The club had two weeks to appeal after the stand-off was banned by the Rugby Football League until 17 March 2008.

"Paul and the club are tired of the distractions caused by endless rumour and speculation in this story," said club chairman Neil Hudgell.

"We detect that is also very much the mood among our supporters."

Inside Sport: Cooke transfer divides Hull

If Hull FC decide to issue civil proceedings against Paul and/or the club we will respond at that time Hull KR chairman Neil Hudgell

He said they wanted to bring the matter to a close but remained confident in the position they had taken in the dispute, and the club would deal with any possible legal action from Hull FC as and when it came.

"We are not going to elaborate on the reasons for not appealing nor commenting on this issue any further, other than to reiterate that if Hull FC decide to issue civil proceedings against Paul and/or the club we will respond at that time," he said.

"We remain as confident in our position as we did at day one. Nothing in the RFL ruling causes us to change that view."

Cooke was found guilty of misconduct for approaching the Robins while still under contract to Hull FC.

The Robins criticised the scope of the RFL inquiry and said they "would welcome the opportunity to bring into the public domain the whole facts and background circumstances surrounding Paul's transfer" if Hull wanted to take the matter to court.

"It is extremely important to understand that this ruling was wholly based on a narrow and self-serving interpretation of the 'registration' rules," continued Hull KR's statement.

"It goes nowhere near answering the all-important question of why a player with nine years' service from the age of 17 would become so disillusioned so as to end his playing career with Hull FC."

Cooke scored 798 points in 221 appearances in his nine seasons with Hull FC and was the hero of their 2005 Challenge Cup triumph over Leeds at the Millennium Stadium with the late match-winning try.
