Qualification for the 2012 Olympics has been changed to go directly to a judoka, not to a nation. What this means is there will no longer be Olympic Trials for judo. Here are some key details:
- Top 22 men and top 14 women in the world ranking for each category will automatically qualify.
- Only one judoka per category per country. This means if there are 2 or more male judoka from the same country in the same category that are in the top 22 of the world, that country chooses which one of them goes.
- That accounts for 252 spots. Then 100 more spots are allocated based on the world ranking within each continent, with at most one athlete per country. This is done to guarantee that at least 100 different nations are represented in the Olympics.
- 14 more places are given to the organizing country (England in this case).
- Last 20 places are reserved for invitation (covering special cases, probably when national politics gets involved).
