A-LEAGUE clubs have decided not to sue Football Federation Australia over the game’s ugly power scuffle but issued a loaded warning to boss Steven Lowy ahead of this week’s pivotal EGM.

The drawn-out deadlock over a new congress model will come to a head on Wednesday when FFA attempt to push through its desired model, one supported by many state federations but staunchly opposed by the clubs and players’ union.

Days before FFA called the EGM earlier this month, incensed clubs wrote to Lowy threatening to seek an injunction to have the meeting -- described by Adelaide United chairman Greg Griffin as an “abuse of power” -- ruled illegal.

But in another charged letter to Lowy on Saturday, Griffin indicated the clubs would leave the legalities in the hands of FIFA.

“Noting that the FFA is one of only a handful of FIFA Member Associations structured as a Corporation, part of our considerations is the apparent current focus of the FFA Board on the Australian Corporations Act over the obligations of the FFA as an Association Member of FIFA,” the letter read.

“Those obligations to FIFA are clearly manifested in the consistent instructions the FFA Board has received from FIFA with regard to governance reform over the last year, and indeed in the seven years prior to that.

“We do not wish to act in any way that might undermine FIFA’s authority in this matter and therefore will not take legal action at this juncture.”

However, Griffin cautioned FFA against following through with the EGM, “a final cynical act” he claimed would destroy the board’s credibility and mandate.

A “commensurate” response would follow should FFA force through its favoured framework, made up of nine state votes, four for the clubs, one for Professional Footballers Australia and one for the women’s game.

The clubs and PFA want a 9-5-1-1 model featuring one extra vote for the clubs, a small but crucial difference that would ensure the nine states no longer have majority power to elect FFA’s board.

Both the clubs and PFA have accused FFA of attempting to remain as the game’s “dominant” or “pre-eminent” stakeholder.

With all parties at an impasse, Wednesday’s result is likely to hinge on one or two key states, with Lowy, the clubs and PFA understood to be lobbying states until the 11th hour.

Even if pushed through, the ultimate decision lies with FIFA, which has already made it clear reforms must be agreed to by all stakeholders -- identified by the world governing body as the states, clubs and PFA.

A resolution must be struck by November 30 or FIFA will remove Lowy and his board and install a normalisation committee to run Australian soccer. It comes a week after Griffin and a forensic auditor began going through FFA’s books, including details of Australia’s failed World Cup bid.

FFA declined to comment but confirmed they will respond to Griffin’s letter.
