b'Section 143 of the 1972 Act enables a local authority to pay reasonable subscriptions to the sums of any association of local authorities formed (whether inside or outside the UK) for the purpose of consultation as to the common interest of those authorities and the discussion of matters relating to local government or of any association of officers or members of local authorities which were so formed. Although this is not a charging but an expenditure power, this section does enable local authorities to get together to form an association which will then be able to charge the constituent authorities a fee for joining and could lead to more efficient local government administration by means of networking and swopping information. Section 144 gives local authorities a power to encourage visitors and provide conference and other facilities, either alone or jointly with other persons or bodies, by advertisement or otherwise, to visit their area for recreation, for health purposes or to hold conferences, trade fairs and exhibitions in their area; and to provide or encourage any other person or body to provide facilities for conferences, trade fairs and exhibitions or improve or encourage any other person or body to improve the existing facilities for those purposes. This is another power that can be utilised in conjunction with section 93 of the 2003 Act or section 3 of the 2011 Act to charge for the provision of such services. Section 145(1) of the 1972 Act states that: a local authority may do, or arrange for the doing of, or contribute towards the expenses of the doing of, anything (whether inside or outside their area) necessary or expedient for any of the following purposes, that is to say: (a)the provision of an entertainment of any nature or of facilities for dancing; (b)the provision of a theatre, concert hall, dance hall or other premises suitable for the giving of entertainments or the holding of dances; (c)the maintenance of a band or orchestra; (d)the development and improvement of the knowledge, understanding and practice of the arts and the crafts which serve the arts; (e)any purpose incidental to the matters aforesaid, including the provision of refreshments or programmes and the advertising of any entertainment given or dance or exhibition of arts or crafts held by them. Under section 145(2) it states that without prejudice to the generality of the above a local authority: (a)may for the purposes [specified above] enclose or set apart any part of a park or pleasure ground belonging to the authority or under their control; (b)may permit any theatre, concert hall, dance hall or other premises provided by them for the [above purposes] and any part of a park or pleasure ground enclosed or set apart . to be used by any other person, on such terms as to payment or otherwise as the authority think fit, and may authorise that other person to make charges for admission thereto; 101'
