Section 48Q of the Home Building Act 1989 (NSW) imposes a mandatory requirement that a person be joined as a party to CTTT building claim proceedings by notice in writing or oral direction; failure to comply renders any order against that person invalid for want of jurisdiction. The irregularity provision in s 32(3) of the CTTT Act does not save breaches of mandatory procedural fairness requirements under ss 28(4) and 35 of the CTTT Act. A CTTT order against a person who was never formally joined as a party is ultra vires and may be set aside by certiorari under s 65(3)(a) of the CTTT Act.
