A more thorough explanation:

Definition: De jure is a Latin term that means "by law" or "by right." It is used to describe a practice that exists according to the law.

For example, in some countries, there may be laws that guarantee certain rights to citizens, such as the right to vote or the right to free speech. These rights exist de jure, meaning they are recognized and protected by law.

De jure is often contrasted with de facto, which refers to practices that exist in reality, but not necessarily by law. For example, while segregation was illegal in the United States de jure, it still existed de facto in many parts of the country.
