Becky Pepper-Jackson was 11 years old and a mediocre runner when she sued the State of West Virginia over a law that barred transgender girls like her from joining girls’ sports teams.
For the next four years, Ms. Pepper-Jackson’s status on the school track team was in doubt as judges blocked the law, then unblocked it and then blocked it again.
Now 15, she is an accomplished shot-putter and discus thrower. A decision about whether she can compete for her final two years of high school will now fall to the Supreme Court, which on Tuesday will hear her challenge to the West Virginia law that supporters said was intended to ensure fair competition for female athletes.
In an interview, Ms. Pepper-Jackson said she was devastated when the law took effect.
“I want to be able to play on the team with my friends, and that’s all I’ve wanted to do,” she said.
