On 9 February, the Supreme Court made a decision that meant that offenders who were on the sex offender register for whom offences had occurred prior to the passing of the 2016 legislation but who were sentenced after that bill was enacted were no longer on the register. The retrospectivity of the legislation that we had passed as a Parliament was no longer applicable. The effect of that decision meant that nearly 600 offenders who were on the register were deregistered or in the process of being deregistered. What was really clear was the intent of Parliament when we passed the original legislation was that they would be included. However, the Supreme Court made it clear that the clarity of our legislation was not sufficient to ensure that that was the case.
