The case of Anderson deals with the Home Secretary's power to set the tariff, or minimum period a convicted murderer must remain in custody until he becomes eligible for release. This power has ensured ministerial accountability to Parliament within the criminal justice system for the punishment imposed for the most heinous and serious of crimes... This judgment will affect only the issue of who sets the tariff in each case. As is proper in a democracy, Parliament will continue to retain the paramount role of setting a clear framework within which the minimum period to be served will be established. I am determined that there should continue to be accountability to Parliament for these most critical decisions... I intend to legislate this Session to establish a clear set of principles within which the courts will fix tariffs in the future...in setting a tariff, the judge will be required, in open court, to give reasons if the term being imposed departs from those principles.
