who has discretion in the criminal justice system
Discretion Discretion has the meaning of acting on one's own authority and judgement. In law, discretion as to legal rulings, such as whether evidence is excluded at a trial, may be exercised by a judge. Some view discretion negatively, while some view it positively. Discretion exists at all levels of law enforcement and in many types of front-line bureaucrats. Discretion has been called "the Art of suiting action to particular circumstances" (Lord Scarman). Those in a position of power are most often able to exercise discretion as to how they will apply or exercise that power. The ability to make decisions which represent a responsible choice and for which an understanding of what is lawful, right or wise may be presupposed. [1]
Judiciary The judiciary (also known as the judicial system or court system) is the system of courts that interprets and applies the law in the name of the state. The judiciary also provides a mechanism for the resolution of disputes. In most nations, under doctrines of separation of powers, the judiciary generally does not make law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case. In other nations, the judiciary can make law, known as Common Law, by setting precedent for other judges to follow, as opposed to Statutory Law made by the legislature. The Judiciary is often tasked with ensuring equal justice under law.
