Australian referee Stuart Dickinson says he still sleeps well at night after his much discussed decision to deny England’s Mark Cueto a try in the Rugby World Cup final.

Many English supporters believed Cueto had scored the try before television match official Dickinson ruled that he put a foot in touch. Replays have showed it was definitely the right decision, despite the winger still suggesting otherwise.

Because of a communication breakdown, Dickinson was unable to look at slow motion or freeze frame views of the angle he wanted. Instead, he had to rely on normal speed replays of the critical angle on which he made his hugely important decision.

Dickinson has touched on the incident in his book The Rugby World Cup Diaries – A Referee's Inside View, which was launched this week.

"I was aware because of the fact there was no slow motion replay or no freeze frame that I knew that the English people would be upset and the crowd," Dickinson said.

"The first face that came up on the screen was Prince William, so I had a bit of a chuckle to myself with that.

"But I knew in my own mind I could sleep straight in bed at night and that I'd made the right decision and that was fine. I was happy with that and I can live with myself."

Dickinson immediately recieved support from IRB referees boss Paddy O'Brien and also, perhaps surprisingly, England's 2003 World Cup winning captain Martin Johnson.

"In his position he (Johnson) could have easily fallen in line and sort of said `I don't know', but that's the quality of the bloke he just calls it as it is," said Dickinson.
