The administrative review process is already effective in identifying and correcting caseworking errors. From April to December 2013, 93% of these administrative reviews were completed within 28 days, and 21% of the administrative reviews requested resulted in the original decision being overturned. This shows that the review process can provide an effective way of correcting errors, and it does so in a speedy and efficient manner, so that periods of uncertainty are addressed. I do not think it does anyone any good to have long and protracted periods of uncertainty. Indeed, we are in the perverse position of having 17 rights of appeal, which are being reduced to four, to ensure that matters are dealt with effectively and appropriately, supplementing the administrative review process outlined in the Bill.
The Bill also requires landlords to check the immigration status of their tenants. That is dealt with in Lords amendments 12 to 15. The scheme includes statutory codes of practice giving the technical detail of how it operates. Lords amendments 12 to 15 address concerns of the Delegated Powers and Regulatory Reform Committee to ensure that those codes have parliamentary oversight.
Lords amendments 25 to 28 deal with student accommodation. The Bill already excluded some student halls of residence from the proposed landlord checking requirement. We concluded that there was scope to go further and broaden the exemption for student accommodation. Educational institutions already have a duty to check the immigration status of their international students, and we do not want there to be double-checking of these persons. The changes therefore strike a sensible balance and minimise regulatory burdens on higher education institutions.
Lords Amendments 17, 35 and 36, which were proposed by Lord Avebury in the other place, correct an historical anomaly relating to the treatment of illegitimate children. Nationality law is complex, and anomalies arise, particularly as aspects of family life have changed since the time of the British Nationality Act 1981. In 2006, amendments to the 1981 Act enabled illegitimate children to inherit nationality from a British father in the same way as a legitimate child. Those amendments were not made retrospective. To have done so could have itself caused problems for individuals who were now adult and had made a life for themselves in a different nationality. These amendments enable illegitimate children born to British fathers before 2006 to register as British if they choose to do so, correcting a historical anomaly by providing a route to citizenship for those who want to take it.
