Trials may be closed at the behest of the government only if it can show "an overriding interest based on findings that closure is essential to preserve higher values and is narrowly tailored to serve that interest". The accused may also request a closure of the trial; in such a case, it must be demonstrated that "first, there is a substantial probability that the defendant's right to a fair trial will be prejudiced by publicity that closure would prevent, and second, reasonable alternatives to closure cannot adequately protect the defendant's fair trial rights".
