“(1) where an Act repeals an enactment, the repeal does not, unless the contrary intention appears, - … (b) affect the previous operation of the enactment repealed or anything duly done or suffered under that enactment; (c) affect any right, privilege, obligation or liability acquired, accrued or incurred under that enactment; (d) affect any penalty, forfeiture or punishment incurred in respect of any offence committed against that enactment; (e) affect any investigation, legal proceeding or remedy in respect of any such right, privilege, obligation, liability, penalty, forfeiture or punishment; Page 10 and any such investigation, legal proceeding or remedy may be instituted, continued or enforced, and any such penalty, forfeiture or punishment may be imposed, as if the repealing Act had not been passed.”

“No punishment without law (1) No one shall be held guilty of any criminal offence on account of any act or omission which did not constitute a criminal offence under national or international law at the time when it was committed. Nor shall a heavier penalty be imposed than the one that was applicable at the time the criminal offence was committed.”
“Nullum crimen nulla poena sine praevia lege poenali: no one is to be convicted or punished without a pre-existing criminal law in force.”
“… since the X v Federal Republic of Germany decision a consensus has gradually emerged in Europe and internationally around the view that application of a criminal law providing for a more lenient penalty, even one enacted after the commission of the offence, has become a fundamental principle of criminal law. It is also significant that the legislation of the respondent state had recognised that principle since 1930.”
“… The court notes that the obligation to apply, from among several criminal laws, the one whose provisions are the most favourable to the accused is a clarification of the rules on the succession of criminal laws, which is in accord with another essential element of article 7, namely the foreseeability of penalties.”
“109. In the light of the foregoing considerations, the court takes the view that it is necessary to depart from the case-law established by the Commission in the case of X v Federal Republic of Germany and affirm thatarticle 7(1) of the Convention guarantees not only the principle of nonretrospectiveness of more stringent criminal laws but also, and implicitly, the principle of retrospectiveness of the more lenient criminal law. That principle is embodied in the rule that where there are differences between the criminal law in force at the time of the commission of the offence and subsequent criminal laws enacted before a final judgment is rendered, the courts must apply the law whose provisions are most favourable to the defendant.”
“It follows that the applicant was given a heavier sentence than the one prescribed by the law which, of all the laws in force during the period between the commission of the offence and delivery of the final judgment, was most favourable to him.”
“The court must therefore verify that at the time when an accused person performed the act which led to his being prosecuted and convicted there was in force a legal provision which made that act punishable, and that the punishment imposed did not exceed the limits fixed by that provision.”
“A defendant sentenced lawfully, in accordance with the prevailing tariff, and when all factors relevant to sentence were known to the sentencing judge, can, in our view, hardly be described as the victim of [a miscarriage of justice]. Secondly, an alteration in the statutory maxima or minima penalty between sentence and reference cannot, in our view, give rise to legitimate grievance. ...”
