Indeterminate Sentencing.

The Strasbourg-based European Court of Human Rights has ruled that the UK’s use of ‘indeterminate sentences’ – where an open-ended sentence is awarded on the understanding a prisoner is rehabilitated – is “arbitrary and unlawful”, reports the Guardian. Open Europe Blog.

Ironically, this may turn out better than you might expect. Indeterminate sentences look and sound worse than they actually are and have been used indiscriminately, post-sentence, to free some of our worst criminals.
When sentences are nailed down, there will be far more transparency and the sentences served may end up having a more rigorous outcome.
Be assured - from that body - this was not the intention.
Sometimes, albeit rarely,  The Law Of Unintended Consequences can work out for the best.
