What is alleged to have happened
The Securities and Exchange Commission announced this matter on May 22, 2023 as release 23-131MR. The respondents named are Gregory Tolpigin (1 individual, 0 entities).
ASIC states that Tolpigin sold on the ASX through accounts at Gleneagle and associated entities without owning or borrowing the shares, which risked settlement failure and distorted the daily gross short-sales report. ASIC also banned him from controlling a financial services business.
This library tags the matter as naked short selling debate, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.
For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.
