Sara Lennman cleared the International Olympic Committee's qualification limits but did not meet the requirement that the Swedish Olympic Committee (SOK) set for the Olympic Games in Paris last summer.
The SOK's requirement states that one must either have a chance of a top-twelve placement or be selected on the so-called future criterion.
Missed Paris Olympic Games
Since the SOK distributes the tickets, the 29-year-old was left without.
A decision that led to her - along with five other athletes - opening a joint case with Cas, the sports arbitration court.
Cas, however, acquitted the SOK and Lennman & Co had to stay home.
In the Tokyo World Championship, she got her revenge.
It means a lot. Ever since the Olympic Games last year and everything that was with it, and to be able to do this and show that I am top twelve - it feels good in the stomach, it does, she says.
I'm very pleased. I did exactly what I should today and it paid off. I got a good receipt and now I'm going to run the final tonight.
You sound surprised?
Exactly. I don't enter this competition and expect a final spot, but I train for it and hope for it, and then I have to do a qualification first. I'm very happy.
In today's final, at 12.54 Swedish time, she will be joined by Fanny Roos.
Roos to final
The 30-year-old made the longest qualifying throw of her career in Tokyo.
It felt stable. I just tried to do what I've done all season. Nice to get 19.14 in the first and then just build on that. I'm satisfied with 19.24 in the qualification, she says.
Axelina Johansson, however, had a tougher qualification and did not advance with 18.29 meters.
I'm super disappointed and sad. I feel that I come here well prepared, set a training PB this week and feel in good shape.
