“First, a life sentence does not become irreducible by the mere fact that in practice it may be served in full. No issue arises under art.3 if a life sentence is de jure and de facto reducible. In this respect, the Court would emphasise that no art.3 issue could arise if, for instance, a life prisoner had the right under domestic law to be considered for release but was refused on the ground that he or she continued to pose a danger to society. This is because states have a duty under the Convention to take measures for the protection of the public from violent crime and the Convention does not prohibit States from subjecting a person convicted of a serious crime to an indeterminate sentence allowing for the offender’s continued detention where necessary for the protection of the public. Indeed, preventing a criminal from re-offending is one of the “essential functions” of a prison sentence. This is particularly so for those convicted of murder or other serious offences against the person. The mere fact that such prisoners may have already served a long period of imprisonment does not weaken the state’s positive obligation to protect the public; states may fulfil that obligation by continuing to detain such life sentenced prisoners for as long as they remain dangerous.”
“… as long as the detention follows and has a sufficient causal connection with a lawful conviction, the decision to impose a sentence of detention and the length of that sentence are matters for the national authorities.”
“In assessing the reasonableness of an opportunity for rehabilitation, the court must take into account all the circumstances; the prisoner’s history and prognosis, the risks he presents, the competing needs of other prisoners, the resources available and the use made of opportunities for rehabilitation.”
“ The suggested discrimination is said to arise as between a defendant in the position of the appellant, and a defendant who committed an identical offence on a similar date, but who was convicted on4 December 2012 . It is certainly true that the effect of the Commencement Order is that IPP is available to be imposed in the case of the appellant but not in the case of that comparator. The appellant submits that this discriminates objectionably against him on grounds of “other status”, namely either (i) his status as a convicted person prior to 3 December or (ii) his status as a prisoner who is subject to an indeterminate sentence. Assuming for the sake of argument that status as a prisoner subject to a particular regime can in some circumstances amount to sufficient status to bring article 14 into question (Clift v UK[2010] ECHR 1106 ), it cannot do so if the suggested status is defined entirely by the alleged discrimination; that was not the case in Clift. For that reason, the second suggested status cannot suffice. As to the first, even if it be assumed in the appellant’s favour that the mere date of conviction can amount to a sufficient status, which is doubtful, the differential in treatment is clearly justified. All changes in sentencing law have to start somewhere. It will inevitably be possible in every case of such a change to find a difference in treatment as between a defendant sentenced on the day before the change is effective and a defendant sentenced on the day after it. The difference of treatment is inherent in the change in the law. If it were to be objectionable discrimination, it would be impossible to change the law. There are any number of points which may be taken as triggering the change of regime. The point of conviction is clearly one, and the point of sentence is another. Neither is, by itself, irrational or unjustified.”
