The Melbourne Storm have been stripped of the 2010 World Club Challenge title, in addition to the two NRL premiership titles they lost last year in the immediate fallout to the salary cap scandal.

The NRL described its new report into the club’s salary cap rorts as a forensic detailing of the mechanisms used in the biggest salary cap breach in the game’s history, which led to the Storm being stripped of two NRL competition titles, prizemoney and fined $500,000.

The report confirmed that Melbourne Storm exceeded the salary cap by just under $3.8 million.

The conduct of four player agents has been questioned.

The quartet are under investigation by the agent accreditation scheme.

“There is an important process to understand in this,” NRL chief executive David Gallop said.

“After a year-long investigation into the Storm, supported by clear admissions from the club chairman and chief executive, the NRL had sufficient information on which to base a penalty in April 2010.

“Indeed given what we knew at that time there was no other option.

“We also flagged the need for further investigation to determine all that had gone on.
