IFA lobbying unit Adviser Alliance says the political momentum generated by the parliamentary debates on RDR presents the best opportunity to revise the Review and reveals it has received an offer to fund a judicial review into the lack of a time limit on client complaints.
Founder Alan Lakey (pictured) says the recent House of Commons debate and the Treasury Select Committee's (TSC's) request for written evidence has put RDR firmly on the political agenda.
"This provides the greatest potential than at any time in the last four years for the FSA to make adjustments to RDR," he says.
"This is our opportunity over the next six weeks to make the most important argument for years."
In the New Year, the not-for-profit organisation is planning to ramp up its activities by examining the possibility of a judicial review into the lack of a 15-year long-stop.
Lakey says a senior director of a fund provider has offered to provide funding for the judicial review.
Ideally, Adviser Alliance is looking for two or three firms to fund the court action, in addition to the organisation's own support. Lakey says he will also consider launching an industry collection for the review.
The Adviser Alliance founder thinks now could be the moment when his organisation's efforts finally begin to bear fruit.
"We have had lots of little races which we have lost but this has made us very fit and we are now fully prepared for the main race."
With the prospect of a judicial review next year, Lakey says Adviser Alliance will in the meantime concentrate on compiling its written evidence to the TSC.
"For now, we must focus on our evidence to the committee - they could do our job for us. The judicial review will only be followed if other routes are dead."
He says senior figures including TSC chairman Andrew Tyrie and MPs Mark Garnier and Harriett Baldwin, who called the RDR debates, "know what they are talking about" and understand the issues at stake.
"I am very much encouraged by the noises the TSC has made," he says. "They seem determined to examine the underlying basis of RDR - and anyone who does this will realise it is not fit for purpose."
Alongside the growing political momentum, Lakey says social media is also providing a powerful voice for the anti-RDR lobby. He points to the rise of anti-RDR blogging and how the previously apathetic are now lending their support to the cause.
"A big portion of those who previously put their heads in the sand believing its a battle that cannot be won have looked around, seen MPs and the Treasury Select Committee getting involved, heard the outrageous comments from Sants and Turner and thought I can make some noise here."
Lakey, partner at Highclere Financial Services, also says there are a number of people yet to come out of the woodwork who could provide additional support.
"We have made a number of friends and a lot of industry people share my view but are not coming out and supporting us," he says.
He adds the practice of anonymous blogging against aspects of the RDR highlights a general sense of unease surrounding criticism of the FSA.
"I have spoken to many people scared of getting a call from the FSA," he says.
