01 / THE PUBLIC RECORD WHAT CAN SAFELY BE SAID
The event, without the fiction of hindsight.
The case, discussed in later judgments, considers whether violent conduct at work arose out of employment. It is a caution against using one legal classification as a substitute for risk assessment.
The reported outcome—psychological and physical injury—establishes the gravity of the event. It does not, by itself, prove a breach, a cause or a person’s liability. A disciplined discussion keeps confirmed fact, witness account, expert inference and unresolved allegation in separate evidential lanes.
02 / LEGAL CONTROL MAP DUTY → EVIDENCE → CONTROL
OHSA section 8 and workplace-violence risk
An intentional act may fall outside COIDA while still exposing a gap in security, escalation or emergency response. The organisation must assess foreseeable violence without assuming every occurrence is legally an occupational accident.
Safe systems of work and reasonably practicable protection
Section 9 protection of learners, visitors and others where relevant
COIDA classification depends on the connection between assault and employment
The proper test is what was reasonably foreseeable, which control should have interrupted the energy or exposure, whether that control existed and worked, and what admissible evidence supports the conclusion.
03 / QUESTIONS THAT MATTER THE INVESTIGATOR’S NOTEBOOK
Five questions the headline cannot answer.
- 01
Was there a known threat or prior behaviour?
- 02
What escalation system existed?
- 03
Could staff summon support?
- 04
Was the physical environment controlled?
- 05
What post-incident support was provided?
For a workplace violence event in education, the enquiry should also preserve the physical scene, electronic records, appointment chain, risk assessments, permits, inspections, maintenance history, competence evidence and the instructions actually communicated to the people exposed.
04 / FROM EVENT TO CONTROL THE 24 LAW RESPONSE SEQUENCE
Do not close the file when the report is signed.
Rescue without creating a second incident. Isolate residual energy. Account for people.
Control access. Photograph condition. Secure documents, data, CCTV and perishable evidence.
Separate verified fact from assumption. Map the task, change points, decisions and failed barriers.
Apply the hierarchy of controls. Assign owners, due dates and an independent verification test.
Confirm implementation in the field. Retain evidence. Feed learning into similar work and sites.

This discussion is based on the public source linked above and is intended for safety education. It is not a final account of disputed facts, not a finding against any person or organisation, and not legal advice. The OHSA, MHSA, COIDA and subordinate regulations apply differently depending on the workplace, undertaking, status of each person and proven facts.
