State secrets privilege

State secrets privilege is a legal rule that lets a government keep some information secret in court cases. It is sometimes called military or national security privilege. If a court determines the information is a state secret, it cannot be used even if it would help the court decide a case. This means that the case may be decided without knowing important information that is a state secret. State secrets privilege is used to protect the country and its citizens by making sure that no dangerous information gets out that could hurt people or put the country at risk.
