Understanding Shared Liability in NSW CTP Claims
In a motor accident in Greater Sydney where more than one driver contributed to the crash, insurers assess fault through a process governed by the Motor Accident Injuries Act 2017 (MAIA). This determines how compensation is distributed. Insurers consider the degree of fault each party bears, which directly affects entitlements to treatment and care benefits, weekly income payments, and any claim for damages. The assessment is not based on a simple yes/no fault determination but on a percentage allocation of responsibility.
How Insurers Evaluate Fault Distribution
Insurers assess shared liability by reviewing all available evidence, including police reports, witness statements, photographs of the scene, vehicle damage, and any video footage. The Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines set out the framework for determining fault. Insurers apply these standards to assign a percentage of fault to each party. For example, if a driver ran a red light and another failed to yield at an intersection, both may be found at fault, with responsibility split 60/40 or 50/50 depending on the evidence.
The insurer must provide a written explanation of how fault was apportioned. This includes a summary of the evidence relied upon and the reasoning behind the assigned percentages. Claimants have the right to request a copy of the insurer’s internal assessment and supporting documentation.
Factors Influencing Insurer Decisions
Several factors shape an insurer’s decision on shared liability. The most critical is the factual evidence of how the accident occurred. Insurers also consider whether any party was acting in a way that constitutes a breach of the Road Rules 2014, such as speeding, distracted driving, or failing to give way. The presence of a driver who was not at fault but was involved in the collision may still be assigned a small percentage of fault if their actions contributed to the risk of impact, even if not the primary cause.
Insurers may rely on independent accident reconstruction reports, particularly in complex crashes involving multiple vehicles or unclear scene dynamics. These reports are often commissioned by insurers or requested by claimants to clarify the sequence of events. The credibility of witness testimony, including consistency and timing of statements, also plays a role.
Challenging Insurer Decisions on Shared Liability
If a claimant disagrees with the insurer’s assessment of shared liability, they may formally dispute the decision. The first step is to submit a written objection, supported by additional evidence such as new witness statements, a different accident reconstruction, or medical evidence showing that a pre-existing condition was not responsible for the injury. The insurer must respond within a reasonable timeframe, typically 28 days.
If the dispute remains unresolved, the claimant may apply to the State Insurance Regulatory Authority (SIRA) for a review. SIRA provides an independent assessment of the insurer’s decision, including a review of the evidence and application of the Motor Accident Guidelines. The review process is free and does not require legal representation, though claimants may choose to seek advice.
A claimant may also seek a determination from the NSW Civil and Administrative Tribunal (NCAT) if a dispute arises over entitlement to damages or the level of impairment. However, NCAT does not reassess fault unless it is directly tied to a damages claim and the claimant has already received a final decision on benefits.
Practical Steps and Evidence to Preserve
Immediately after a motor accident in Greater Sydney, claimants should:
- Report the incident to the police if there were injuries, significant property damage, or a dispute about who was at fault.
- Take photographs of the vehicle damage, road conditions, traffic signs, and the surrounding area.
- Collect contact details from any witnesses.
- Seek medical attention even if injuries seem minor, as some symptoms may not appear immediately.
- Keep a record of all communications with insurers, including dates, names, and summaries of conversations.
These steps help ensure that evidence is preserved and can be used to support a claim or challenge an insurer’s assessment.
Time Limits and Procedural Requirements
A claim for compensation under the CTP scheme must be made within three years of the accident date. This time limit applies regardless of whether fault is disputed. Failure to meet the deadline may prevent a claim from being heard, even if the evidence supports a valid case.
There is no automatic right to a damages claim in a shared liability scenario. To recover damages, a claimant must meet the threshold for a serious injury under the MAIA. If only minor or threshold injuries are sustained, benefits are generally limited to 52 weeks of treatment and care, and weekly income payments, as the law provides. This restriction applies even if fault is shared.
Hypothetical Example
A pedestrian was struck by a car while crossing a footpath in Sydney’s inner west. The driver claimed they were not at fault because the pedestrian stepped into the road unexpectedly. The insurer initially assigned 70% fault to the pedestrian and 30% to the driver. The claimant submitted a video from a nearby business showing the pedestrian had stepped off the curb only after the traffic light had turned green. The insurer revised the fault split to 50/50. The claimant was then entitled to 50% of treatment and care benefits and weekly payments, but not damages, because the injuries were classified as threshold injuries under the Motor Accident Guidelines.
