129.Section 49 amends the British Nationality Act 1981 in regard to the requirement under that Act to be "of full capacity". The requirement applies where the applicant is seeking to be naturalised, to renounce citizenship or to resume citizenship following a previous renunciation. The effect of the amendment is to confer on the Secretary of State a discretion to waive the requirement to be of full capacity if, in the circumstances of a particular case, he considers it in the applicant's best interests to do so.
