Samoa's IRB representative Harry Schuster wants an investigation into former All Black Simon Mannix's allegations that French club Racing Metro paid three Fijian players not to go to the World Cup last year.
"The IRB rules are very clear and should be enforced. The problem of player availability is a recurring issue for the Pacific Islands and smaller nations. If we had the money, we'd have taken someone to court already, said Schuster.
"The IRB have to bring this to a head now, investigate and find out what's going on. Otherwise the same scenario is going to happen again and again. Players should not be put in a situation where they are bullied by rich men into not representing their countries."
Schuster said that players find themselves in a Catch 22 situation where they might want to play for their countries but would be penalised financially by their clubs.
Sireli Bobo and Jone Qovu pulled out of the Fiji squad citing personal reasons, while Josh Matavesi withdrew citing club commitments.
Former Samoan international-turned-agent Freddie Tuilagi said in The Independent that his brothers Alesana, who represented Samoa, and Manu, who represented England, both had their wages docked by 50 per cent at the last World Cup by English club Leicester in a clear breach of IRB regulations.
English players were paid an estimated £50,000 ($97,000) for the duration of the tournament - but cash-strapped Samoa can't pay that kind of money.
Schuster is due to attend an IRB meeting in Dublin this week where issues of player availability will be discussed. IRB president Bernard Lapasset promised there would be strong sanctions against the Parisian club if found guilty - though no inquiry has yet been launched.
Rugby insiders believe French and English unions have no stomach for a fight with clubs and their powerful owners while rugby's governing body are yet to show any enthusiasm to tackle the issue.
Lapasset acknowledged that there have been rumours of clubs being in breach of IRB's regulation 9 (on player availability) for years. However, no club has ever been brought to book.
