{ 12) son, or by a body of Commissioners, of whom the Lord Chancellor is usually one. The Houses of Parliament communicate with the Sovereign by addresses. The Sovereign appoints, either directly or by delegation, all Judges. In the case of the superior Judges, except the Lord Chancellor, they are appointed for life, and cannot be removed except for misbehaviour, and then only upon an address of both Houses of Parliament. All prosecutions for offences run in the name of the Sovereign ; and the Sovereign can, with few exceptions, pardon all offenders against Criminal Law, either before or after conviction. This prerogative cannot be exer cised in the case of an impeachment by the Commons in Parliament ; or in that of committing any person to prison out of the realm contrary to the Habeas Corpus Act; or where the pardon would inflict an injury on an innocent person. It is usually exercised (1) where fresh evidence tending to exculpate the accused is discovered after the trial ; (2) where it is discovered that evidence relied upon at the trial was untrustworthy, and that justice has consequently miscarried ; (3) where the judge himself sees reason to make recommendations against a finding of a jury; and (4) in political offences after the danger has subsided. A pardon may be free or conditional ; and is frequently offered as an inducement to participators in a crime to turn Queen's evidence.
