My hon. Friend tempts me into a broader debate that extends beyond the statutory instruments and deals with preventing from returning
to this country people who have engaged in activity contrary to the interests of this country. This issue was considered at length in this House and the other place, and it was determined that TEOs were the appropriate mechanism, considering our international obligations and the issues he highlighted of legal challenge and ensuring an effective mechanism. We judge that the TEOs provide this, but we recognise the potential for challenge. Indeed, we have built in an oversight process through the scrutiny of the judiciary.
I hope that I can assure my hon. Friend that the rules are based on those used for similar preventive measures, such as terrorism prevention and investigation measures, some asset-seizing legislation and closed material proceedings, and therefore are based on the experience and judicial oversight applied to those rules. I hope that gives him some assurance of the careful consideration we have given to the rules.
