The practice that allows the government to stop the publication of sensitive materials related to national security is known as prior restraint. Prior restraint is a legal concept that refers to the government's ability to censor or prevent the publication or dissemination of information before it is published. It is often justified by citing national security concerns or the potential harm that the release of sensitive information could cause. However, prior restraint is generally seen as a limitation on freedom of speech and press, and is subject to constitutional scrutiny in many democratic countries.
