How NSW CTP Insurers Assess Liability in Partial Fault Claims
Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).
A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
NSW CTP insurers assess liability in partial fault claims by determining the proportion of fault each party contributed to the accident. This process involves evaluating evidence such as traffic rules, witness statements, and police reports. Shared liability is calculated based on fault percentages, which directly impact compensation entitlements. In Western Sydney, insurers apply the Motor Accident Injuries Act 2017 and SIRA guidelines to determine fault contributions.
Legal Framework for Partial Fault Claims
Under the Motor Accident Injuries Act 2017, CTP insurers must assess fault based on the 'contributory fault' principle. Section 4.4 of the Act specifies that compensation is limited to injuries caused by the insured party’s fault. SIRA’s guidelines clarify that insurers must consider all evidence to allocate fault fairly, including traffic camera footage, expert reports, and driver statements. Fault percentages are not assumed equally unless evidence supports a 50-50 split.
Factors Insurers Consider in Western Sydney Claims
Insurers evaluate several factors to assess fault in partial fault scenarios:
- Traffic rules and actions: Whether drivers followed signals, speed limits, or right-of-way rules.
- Witness statements: Accounts from bystanders or other drivers.
- Police reports: Official documentation of the accident scene.
- Vehicle data: Black box or camera evidence.
- Injury causation: Whether the fault directly caused the injury.
For example, if a driver ran a stop sign (70% fault) and another driver distractedly texted (30% fault), the insurer would allocate 70% of liability to the first driver and 30% to the second.
Evidence Required to Determine Fault Percentages
Insurers require clear evidence to establish fault percentages. Medical records may show injury severity, but fault is determined by the accident’s circumstances. SIRA advises that insurers must document their fault assessment in writing, including reasons for percentage allocations. Drivers should preserve evidence like:
- Photos of the accident scene
- Witness contact details
- Police report copies
- Vehicle damage assessments
Time Limits and Dispute Resolution
CTP insurers must respond to claims within 28 days of receiving all evidence (Motor Accident Injuries Regulation 2017 s 12). If a claimant disagrees with the fault assessment, they may:
- Request a review in writing
- Seek mediation through the NSW Civil and Administrative Tribunal (NCAT)
- Lodge a complaint with the Financial Ombudsman Service
Claims involving injuries exceeding the 'threshold injury' definition (e.g., whiplash with neurological signs) may require expert medical opinions to determine fault impact.
When to Seek Legal Advice
Contact a solicitor if:
- The insurer refuses to acknowledge fault
- The fault percentage seems unfair
- The injury involves complex medical evidence
- The claim exceeds 52 weeks of benefits
Legal professionals can help challenge fault assessments or negotiate better outcomes. Always act within the 52-week statutory limit for benefits unless the injury meets the 'whole person impairment' threshold.
