92.Section 26 provides that the powers to appoint agents, nominees and custodians conferred by Part IV are in addition to any other powers vested in the trustees but are subject to any limitations in the trust instrument or legislation. In short, the powers are general default provisions which will not override specific provision.  “Subordinate legislation” is defined in section 6(2).  Section 26 is to the same effect in relation to Part IV as are sections 6 and 9 in relation to Part II and III respectively.
