Long ago, in the year 1920, there was a special court that was kept a big secret. This court was made up of important people in the government who would meet in private to make decisions about what to do with people who were accused of doing things that were very bad for the country.
The reason why this court was a secret is because it dealt with very sensitive matters that the government didn't want other countries to find out about. The leaders of the government wanted to make sure that they were doing everything they could to protect the country, so they created this secret court.
The members of the court would talk and listen to evidence to decide what punishment the person should get if they were found guilty of doing something bad. Sometimes the evidence they heard was so secret that no one else was allowed to know about it.
While it's important for the government to protect the country, some people didn't like that this court was kept a secret. They thought that it was unfair because the person being accused didn't have a chance to defend themselves in public and didn't get a fair trial.
In the end, the secret court of 1920 is a part of history that reminds us how important it is to balance national security with the need for transparency and fairness in the legal system.
