I don't want to speculate too broadly on that because I think it's something that the courts would certainly turn their mind to if it came up as an issue in a particular case. I can say that I recall having heard that in the U.K. they did re-examine some sentences for individuals when there was no longer an offence. I think it was, for example, same-sex relationships from decades ago. I think they did do some kind of review of the kind of conviction and sentence that had been imposed when afterwards the law had evolved.
