The right to a public trial is strictly enforced, but is not absolute. Trials may in exceptional cases be regulated. Closures are decided case-by-case by the judge evaluating a claimed danger to a substantial or legitimate public interest. But whatever the interest at stake, the likelihood of danger to that interest must meet a "‘substantial probability’ test". Examples of cases presenting closure issues include organized crime cases (overall security concerns), rape cases (decency concerns), juvenile cases, and through the Silent witness rule and/or Classified Information Procedures Act, cases involving sensitive or 'classified' information.
