registered review adjudicator
The matters Christopher adjudicates include substantial, closely-examined disputes. Determinations he has made have been the subject of judicial-review proceedings in the Supreme Court of New South Wales, the New South Wales Court of Appeal, and the Supreme Court of the Australian Capital Territory, across matters ranging from residential subcontracts to commercial claims worth into the millions.
Statutory adjudication is a rapid, interim process: it keeps cash moving on a “pay now, argue later” basis while the parties’ final rights are preserved, and a court considers a determination only for jurisdictional error rather than re-hearing the merits.
