Section 4 provides for various amendments to the Local Government Act 2001 consequential on the substantive changes to the Act made by the Bill affecting the dual mandate and direct election of cathaoirligh. The discontinuation of the arrangements for direct election of cathaoirligh of county-city councils is effected by section 7 by way of the repeal of Chapter 3 of Part 5 of the Local Government Act 2001. The amendments set out in the Schedule are largely consequential on that repeal and the insertion of the new section 13A. The amendment to section 167 of the 2001 Act, however, clarifies that specified provisions of the new ethics regime apply to all local authority employees. These are a duty to maintain proper standards of integrity, a prohibition on seeking or accepting rewards arising from one's duties and a code of conduct. Section 5 amends section 97 of the Planning and Development Act 2000 to insert a minor amendment omitted by the Planning and Development (Amendment) Act 2002.
