Chambers won the British Olympic trials but could not take up his place
Sprinter Dwain Chambers has no plans to fight a lifetime Olympic ban in the courts again, effectively ruling himself out of London 2012.
Chambers lost a High Court case in July to get an injunction against a British Olympic Association ban so that he could race in the recent Beijing Games.
He is banned from any Olympics by the BOA after a positive drug test in 2003.
"Dragging the sport back through another court case is just going to be wrong," he told BBC Radio 5 Live.
"It's going to put a lot of pressure on everybody else.
"So, for now, we are just going to leave that alone and concentrate on making sure the next three years are as competitive as possible."
Chambers tested positive for THG in 2003 and served a two-year doping ban.
He said he would not prevent other people taking on his cause for him to compete at an Olympics but recent experiences have put him off going down the legal action route.
"I would let it happen but I'm not going to be the one to instigate it," he added.
"I've been down that road and it was a hard road to get back up from. I'm still somewhat subdued because of that.
There is a lot of mending to do

"It's tough to get a knock like that and try to pick yourself back up. We are just going to take our time and make the right decisions at the right time."
Chambers has been buoyed by the recent comments of the new head coach of UK Athletics, Charles van Commenee, saying the 100m runner would be welcomed back into Team GB.
"It's a surprise because I never expected such a sudden turn around at this stage of the season," said Chambers.
"I was expecting to face more turmoil and constant questions about my past leading into next year. To hear Charles' statement is very warming.

"Charles has put on a breath of fresh air as no-one wants to talk about the same thing over and over again.
"Now that Charles has said what he has it obviously means that he and UK Athletics are prepared to move forward and, with that in mind, hopefully we can look forward to a more positive outlook next year."
Chambers will run in his 100m speciality but also wants to take part in the relay again, depending on the stance of his team-mates.
The teams in which Chambers won European 2002 relay gold and 2003 world silver had their medals taken off them because Chambers used performance-enhancing drugs.
"There is a lot of mending to do," said Chambers. "I'm going to put myself forward and explain to the individuals my reasons for wanting to take part in the relay.
"If the members accept it then fine and if not then I would just have to concentrate on the 100m.
"Hopefully, we can put the past behind us and move forward in the attempt to gain medals."
