In the context of trials, the isolation of a jury from the public, or the separation of witnesses to ensure the integrity of testimony. In a jury trial, a judge may choose to sequester the jurors, or place them beyond public reach. Jurors are moved into a hotel, kept under supervision 24 hours a day, denied access to outside media (TV and newspapers), and allowed only limited family contact. Jury sequestration is rare, and has two broad purposes: to avoid the accidental tainting of the jury, and to prevent others from intentionally tampering with jurors by bribe or threat. In witness sequestration, witnesses typically are ordered not to attend the trial, or follow accounts of it, until they are called to testify. This judicial order is intended to assure that the witnesses will testify concerning their own knowledge of the case without being influenced by testimony of prior witnesses.
