The FIA has slated suggestions that personnel have "disclosed sensitive information" while confirming a delay in the awarding of certification to F1 teams.
Wednesday had been marked as the day that the fog would lift on the cost cap debate that marred the Singapore Grand Prix with allegations of breachs spreading around the paddock.
But after stating on Wednesday morning that it would provide an update "regarding timelines for the financial regulations compliance process in next couple of hours", the FIA confirmed a delay late in the afternoon.
"The FIA informs that the conclusion of the analysis of the 2021 financial submissions of the Formula 1 teams and the subsequent release of Certificates of Compliance to the Financial Regulations will not take place on Wednesday, 5 October," read an FIA statement.
"The analysis of financial submissions is a long and complex process that is ongoing and will be concluded to enable the release of the Certificates on Monday, 10 October.
"The Financial Regulations were agreed unanimously by all Competitors, who have worked positively and collaboratively with the FIA Cost Cap Administration throughout this first year under the Financial Regulations."
During the Singapore weekend, the FIA felt compelled to make a statement on allegations that two teams, namely Red Bull and Aston Martin, had been found to have breached the prescribed spending limits.
While confirming the schedule for the coming, the FIA reiterated its faith in its personnel.
The statement continued: "As previously communicated, there has been significant and unsubstantiated speculation and conjecture in relation to this matter, and the FIA reiterates that until it is finalised, no further information will be provided.
" The FIA also reiterates that any suggestion that FIA personnel have disclosed sensitive information is equally baseless."
