People often believe that having a pre-existing condition prevents them from receiving compensation after an accident or workplace injury. That assumption is incorrect. In many cases, a pre-existing conditions claim or a pre-existing injury claim can still succeed if the incident made the health issue worse, accelerated its development, or caused new complications. Understanding how the law in Western Australia treats these cases is essential to protecting your rights and securing the compensation you deserve.
Our legal team at Separovic Injury Lawyers regularly assists clients whose injuries are complicated by pre-existing medical conditions. With careful preparation, strong medical evidence, and skilled advocacy, you can obtain a fair outcome that reflects the true impact of your accident.
Understanding Pre-Existing Conditions
A pre-existing condition is any medical issue, injury, or illness that existed before the accident or incident forming the basis of your claim. Common examples include:
- Old back injuries or disc problems.
- Arthritis in the knees or hips.
- Asthma, diabetes, or other chronic illnesses.
- Previous fractures or joint injuries.
What matters most is not whether the condition existed, but how the new incident affected it. The law recognises that a worker with a history of back pain might experience serious aggravation after lifting heavy equipment at work, just as a driver with prior knee problems could suffer lasting damage after a car accident.
Key points to remember:
- A pre-existing condition does not automatically disqualify your claim.
- The key issue is whether the incident aggravated, accelerated, or exacerbated your condition.
- Compensation is available for the additional harm caused.
How Pre-Existing Conditions Affect Claims
When an accident interacts with a pre-existing health issue, the impact usually falls into three categories:
- Aggravation – The incident made the existing condition worse.
- Example: You had occasional lower back discomfort, but after a workplace fall, the pain became chronic and debilitating.
- Acceleration – The incident sped up the natural progression of the condition.
- Example: Arthritis might have required a knee replacement in 10 years, but the accident made surgery necessary immediately.
- Exacerbation – The incident triggered a temporary flare-up.
- Example: A worker with eczema suffered a severe outbreak after a chemical spill.
In all these situations, you can pursue a pre-existing conditions claim for the additional pain, suffering, and medical costs. The law draws a clear line: the incident does not need to create a brand-new injury; it only needs to worsen the existing condition in a measurable way.
Key points to remember:
- Focus on the effect of the incident on your health.
- You can claim for new harm caused, even if the base condition existed before.
The Eggshell Skull Rule
Australian law applies the “eggshell skull” principle. This rule requires that defendants accept victims as they are, regardless of vulnerabilities. In practical terms, this means that if someone’s pre-existing condition makes them more fragile, the party responsible for the incident must still cover the full extent of the injury.
Analogy: Think of the legal process as a driver on the road. If you bump into another car, you are liable for the damage. If the other car was already dented, you are still responsible for the new damage caused by your impact. The fact that the vehicle wasn’t in perfect condition does not excuse your liability.
The “eggshell skull” rule ensures that individuals with pre-existing conditions are not disadvantaged when seeking compensation.
Key points to remember:
- Liability extends to the full harm caused.
- Vulnerabilities do not reduce the defendant’s responsibility.
Proving Aggravation or Exacerbation
Successfully pursuing a pre-existing injury claim requires clear evidence that the incident worsened your condition. The key types of evidence include:
- Medical Records: Documentation before and after the incident shows how your condition changed.
- Expert Medical Opinions: Specialists can explain how the accident aggravated or accelerated your condition.
- Witness Statements: Testimonies from colleagues, family members, or friends can confirm your health before and after the incident.
Our legal team often engages independent medical specialists to provide expert reports. These reports can be decisive when an insurer attempts to argue that symptoms are unrelated to the accident.
Key points to remember:
- Proof requires detailed medical evidence.
- Independent experts strengthen your case.
Gathering Evidence
Evidence builds the foundation of your claim. Without it, insurers may attempt to dismiss your injury as unrelated to the incident.
Essential evidence includes:
- Incident Report: A detailed workplace or accident report including date, time, and description.
- Medical Documentation: Doctor’s notes, scans, treatment plans, and test results.
- Photographs or Videos: Of the accident scene, equipment, or visible injuries.
- Daily Journal: A record of pain levels, mobility issues, and the impact on everyday activities.
Fictional Example: Sarah, a warehouse worker, lived with mild knee pain from a sporting injury years earlier. One day she lifted a heavy box, twisting her knee badly. The pain became severe and she struggled to walk. Sarah reported the incident, attended hospital, and kept a daily journal of her pain. With a doctor’s report linking the new injury to her workplace incident, Sarah successfully proved that the event had aggravated her pre-existing condition, and she secured compensation for treatment and time off work.
Key points to remember:
- Collect every possible form of documentation.
- A daily journal provides a powerful personal record of your suffering.
Negotiating with Insurance Companies
Insurers often attempt to reduce liability by arguing that your symptoms are solely the result of a pre-existing condition. They may claim that the accident made no meaningful difference to your health.
This is where skilled legal representation matters. A strong pre-existing conditions claim is built on medical evidence, logical arguments, and persistence in negotiations. Our lawyers emphasise the medical evidence and the “eggshell skull” rule to demonstrate that the accident aggravated the condition, and that compensation is warranted.
Key points to remember:
- Insurers may minimise or deny claims involving pre-existing conditions.
- Strong negotiation backed by evidence ensures fair treatment.
When to Seek Legal Advice
If an insurer challenges your claim or you feel overwhelmed by the process, professional legal advice becomes essential. A personal injury lawyer Highgate or a workers’ compensation lawyer Perth can assess your case, gather evidence, negotiate with insurers, and represent you in court if necessary.
Legal guidance is especially important when:
- The insurer disputes causation.
- Your condition worsens significantly after the incident.
- You require ongoing or costly treatment.
- Your ability to work is affected.
Key points to remember:
- Legal advice strengthens your position.
- Lawyers ensure deadlines are met and your rights are protected.
