Official FIA Press Release.

Amendment to 2008 FIA Formula One World Championship Sporting Regulations.

Overtaking moves may no longer be made using the process known as "out braking into a corner". This process is seen to be elitist and experience has shown that some drivers are better than this than others. European Parliament rulings have stated that all competitions must be fair, so to comply with that, persons who clearly have more of a talent than others shall be penalised to enable those without talent to continue in equal competition.
Since the FIA is based within an EU country, it is bound by those rules.

To fully comply with the EU fair competition ruling, all tracks will be upgraded by 2010 to allow all 22 cars to line up side-by-side. No out accellerating or out braking manouvers will be permitted. All cars to be synchronised such that they all cross the finish line together, permitting fair competition without allowing elitist tendencies of "winners and losers".
