The 2001 act is clear about the powers that it gives us. Under section 69(2)(a), an order may"transfer to a joint board comprised of such local authorities as may be specified in the order (such authorities being referred to in this section as the "constituent authorities") such property, rights and liabilities of the relevant body to which the order relates as may be so specified".That is clear.Section 81(2)(a) says that any power to make regulations under the act shall include"different provision for different cases and for different classes of case".In other words, the act allows us to implement our power to create a board in a different way on the Forth or the Tay as circumstances dictate.
