Under the Building and Construction Industry (Security of Payment) Act 2009 (ACT), the claimed amount stated in a payment claim defines the upper limit of the amount an adjudicator may award, and the Court may determine the claimed amount for itself when reviewing for jurisdictional error. An adjudication decision that awards more than the claimed amount is void for jurisdictional error and cannot be severed to preserve the valid portion. Payment claims under the SOP Act are to be construed objectively, as commercial documents, considered as a whole and in their commercial context.
