Back in 2009, after an uneasy peace broke out during the most acrimonious season in recent Formula 1 history, 2012 was slated as the final year of the old F1 with its antiquated regulations (some of which hark back to the 1990s); the final season under a make-shift Concorde Agreement.
For the first time, F1 would synchronise its outline regulations and the sport's regulating document in such fashion that both would become effective at the start of 2013, then run through to the end of 2017. To this end the teams made a good start when they extended the Resource Restriction Agreement as framed by their umbrella body, the Formula One Teams' Association, to that point. Alas, it proved too good to be true...
Concorde will still expire on the due date, but as we have seen in the past - when F1 ran the full 2008-'09 seasons without a binding agreement in place - the three signatory parties could well be content to continue under the existing document, itself hurriedly contrived, yet markedly superior to its long-in-the-tooth tripartite predecessor framed back in 1997.
However, even the latest iteration was found chronically wanting when it came to regulation changes, with the net result being that the FIA (on the one side) and the commercial rights' holder and teams (collectively on the other) disagreed on a timeframe for the introduction of the sport's planned 'green' engine regulations.
