Checked against the primary document on October 3, 2026. The library's summary, tags and figures for this record were compared with the regulator's own document by an AI model (Claude) following written instructions, with sampled and disputed records read a second time.

Sentence was pending; later notes record a sentence date of June 4, 2020.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

Wong appeared at the Downing Centre Local Court and was committed to the District Court in Sydney for sentence. ASIC's later editor's notes record repeated adjournments, a sentencing hearing on May 15, 2020 and a reserved judgment to be delivered on June 4, 2020. The release states no sentence.

What technique is this, and how does it work?

This action is tagged with one technique in our taxonomy. The tagging is ours: regulators charge statutory provisions, not technique names, so the mapping is an editorial judgement described in our editorial policy.

Same matter

The library links these 3 records because they appear to concern one matter: the same lead defendant, an overlapping technique tag and close filing dates, or a shared court docket or a release that cites the other. Records are listed by date filed.

This grouping is the library's, made by matching names, techniques, dates and citations when the site is built. It is not the regulator's or a court's determination that the records are one case, and it errs towards missing a link rather than making a false one.
