Lausanne (Switzerland), June 1: A decision by the Court of Arbitration for Sport here has robbed retired Jamaican sprinter Usain Bolt of his perfect record in the 4×100m relay.

The CAS on Thursday dismissed Bolt's teammate Nesta Carter's appeal against disqualification from the 2008 Beijing Olympics for a positive doping test leading Bolt to lose his ninth gold medal, the Sun reported.

In a statement released by the CAS panel for the discoveries made eight years later, the sports body said: "Could not accept any of the arguments raised by Carter contending that the test results should be ignored or the IOC (disciplinary) decision should otherwise be overturned for certainly alleged failures".

Carter had run the opening leg in the 4×100-metre relay when Bolt took the baton third and helped Jamaica win in a world record of 37.10 seconds.

In the fresh analysis of Beijing samples by the International Olympic Committee in 2016, Carter tested positive for the stimulant methylhexaneamine.

Jamaica was disqualified and stripped of the relay title. With Jamaica's disqualification confirmed again, the gold medals will go to the Trinidad and Tobago team of Keston Bledman, Marc Burns, Emmanuel Callender, Richard Thompson and Aaron Armstrong. The IOC would also upgrade Japan to silver and Brazil to bronze, reported Chicago Tribune.

The verdict was expected, and it spoiled Bolt's perfect Olympic career of three gold medals in the 100, 200 and 4×100 at three consecutive games in 2008, 2012 and 2016, Washington Post reported. The Jamaica team in Beijing also included Michael Frater and Asafa Powell.

Carter, now 32, was also on Bolt's team for three straight world championship relay gold medals, in 2011, 2013 and 2015. They also partnered when Jamaica set another 4×100 world record in 2012 at the London Olympics.

Dozens of athletes tested positive for banned drugs in an IOC-ordered reanalysis program using new and more accurate tests on samples stored since the 2008 Beijing Olympics and 2012 London Olympics. Carter's case was the only one involving Jamaica.
