Claiming for an Accident Caused by a Medical Episode (e.g., Heart Attack, Seizure)?

When accidents occur because of sudden medical episodes like heart attacks, seizures, strokes, or diabetic episodes, determining liability can become a complex issue. In a nutshell, within Queensland, liability depends on whether the person experiencing the medical episode knew about the risks involved and took actions to prevent accidents from happening in the first place.

Okay, so while a medical emergency typically won't result in liability, there are cases where those who ignore symptoms, fail to manage a condition which they were fully aware of, or engage in risky activities despite medical warnings may face legal consequences. After all, it could be said that they have unnecessarily put others at risk.

It really comes down to that thin line between whether the accident falls under ‘unforeseeable medical episode’ or ‘negligent behaviour’. Understanding where your situation falls would determine whether you have a right to be compensated. 

So, whether you're a driver who’s suffered a heart attack, a worker who’s collapsed on site, or, on the other side of things, someone injured by another person's medical episode, understanding Queensland's legal framework can help you to clarify your rights and obligations.

Below, in this article, we’ll take a look into Queensland's liability laws, recent case developments, and practical guidance for those seeking compensation after accidents involving medical episodes. Let’s get started. 

Quick Summary

  • Liability depends on whether the accident was in anyway foreseeable: sudden, difficult to predict medical episodes typically don't create liability, but being negligent when it comes to known conditions certainly can
  • Queensland's Civil Liability Act 2003 establishes duty of care standards based on what a reasonable person would do
  • Claims must be made within 3 years, whereas demonstrating medical negligence requires initial notice within 9 months
  • Being equipped with evidence of prior medical warnings or symptoms is crucial for establishing liability

Who This Affects: Anyone injured in car accidents, workplace incidents, or public places due to another person's medical episode, but also those who caused accidents during their own medical emergency

Main Legal Framework: Civil Liability Act 2003 (Qld) , Personal Injuries Proceedings Act 2002 , and relevant insurance schemes

When to Seek Advice: Aim to do this immediately after any accident involving medical episodes. Doing this straight away can help to preserve evidence and meet strict notification deadlines

Understanding Liability for Medical Episode Accidents

As mentioned in the introduction, liability for accidents in this context hinges on how foreseeable the accident was. If someone experiences a completely unexpected medical emergency with no prior warning signs, they generally won't be held liable for the resulting accident. However, this might not always be the case. In fact, liability may arise when the person: 

  • had knowledge of a medical condition that could, without warning, incapacitate them
  • ignored symptoms or medical advice about their condition
  • failed to take prescribed medication or follow treatment plans
  • continued high-risk activities (like driving) regardless of the medical advice they were given

Let’s look at an example: a driver who suffers their first-ever heart attack where there were no prior symptoms typically won't face liability. On the other hand, someone who is diagnosed with epilepsy and who drives without taking their medication, which would have prevented them from having a seizure, could be held legally responsible.

The key question that the court will ask is: "Would a reasonable person in the defendant's position have foreseen the risk and taken steps to prevent harm?" 

This standard, established under Queensland's negligence laws, focuses exactly on what is at stake: was this person able to take steps to minimise potential harm?

Your Rights and Obligations

What Are Your Rights if Injured:

  • Compensation for medical expenses, lost earnings, as well as pain and suffering
  • Access to rehabilitation and ongoing medical care
  • Right to legal representation throughout the claims process
  • Protection from unfair settlements through mandatory pre-court procedures

Your Obligations:

  • Report accidents as soon as you can to the relevant authorities (including the police, your employers, and your insurance company)
  • Seek immediate medical attention and follow treatment recommendations as best as you can
  • File claims within statutory time limits (this being 3 years for most personal injury claims)
  • Provide truthful information about the circumstances of your injury

Real-Life Examples: A construction worker, let’s call him Dave, suffers from diabetes. One day, he fails to monitor his blood sugar levels correctly and collapses, injuring a colleague who had been standing next to him. In this case, Dave may face liability if it can be shown he ignored medical advice. 

On the other hand, let’s take an Uber driver, who we’ll call Sandra. Sandra experienced a stroke while driving her taxi. She didn’t have any prior symptoms and so had no way of knowing the incident was going to happen when and how it did. Here, she would not typically be liable for the injury caused to her passengers.

Being Practical: If you're injured by someone during a medical episode, gather evidence of whether they had prior knowledge of their condition. Medical records, witness statements about previous incidents, and evidence of medical advice the defendant has ignored will all go towards strengthening your claim.

FAQs

For cases like these, a number of issues can arise, making it difficult to correctly assess the merit of a claim. Hopefully, some of the responses below will answer some of your doubts:  

Can someone be liable if they have a heart attack while driving and cause an accident? 

Generally, no liability exists for a first-time, unforeseeable heart attack. However, liability may be a factor if the driver had previously suffered from symptoms related to their heart, ignored medical warnings, or continued driving after being told not to by a medical professional.

What if someone with epilepsy causes a workplace accident during a seizure? 

Liability depends on whether they disclosed their condition to their employer and were following a course of medical treatment. Failing to take the prescribed medication or working in roles where they shouldn’t be could make them liable.

How do you prove someone knew about their medical condition? 

Evidence may include medical records showing prior consultations, prescription histories, witness testimony if a previous episode or accident had occurred, and documentation which shows the medical advice the individual received.

Are there different rules for professional drivers? 

Yes, professional drivers have to, as a rule, disclose more about their condition. They must report this to licensing authorities and may face stricter liability standards due to their professional duties.

What compensation is available for victims? 

Compensation covers medical expenses, lost wages, pain and suffering, and future care needs. Recent awards from courts in Queensland have ranged from $50,000 for minor injuries to over $750,000 for severe, permanent disabilities.

Can families claim if their relative dies in an accident caused by a medical episode? 

Yes, family members may claim through laws pertaining to wrongful death and seek compensation for dependency losses and funeral expenses.

How long do I have to make a claim? 

You have three years from the injury date for most personal injury claims, though medical negligence cases require initial notice within nine months.

What if the accident involved multiple causes? 

In Queensland, responsibility for an accident can be shared between the driver who had the medical episode and others who may have contributed to it.

Key Legal Framework

The ones to know:

Regulatory Framework: The Civil Liability Act establishes that a person breaches their duty of care if:

  • The risk of harm was foreseeable and not insignificant
  • A reasonable person would have taken precautions against that risk
  • The precautions were reasonable given the circumstances

Recent Changes and Developments

Significant Court Decisions: Recent cases within Queensland have emphasised the importance of credible evidence in establishing liability. The Sawyer v Steeplechase case, in 2004, awarded $781,000 for workplace injuries for example. It shows that courts may hold employers responsible if they don’t manage obvious risks, including those linked to a worker’s health.

Legislative Stability: While no major legislative changes occurred between 2023-2024, courts continue to apply established principles strictly, particularly regarding evidence requirements and standards relating to who caused the accident.

Emerging Trends: There’s a tendency for courts now, more than ever, to scrutinise the quality of medical evidence. More and more, they require clear expert testimony linking medical conditions to the reason for the accident. Claims lacking comprehensive medical documentation face higher rejection rates.

Future Outlook: Expect continued emphasis on early legal intervention, robust evidence collection, and expert medical testimony to be all important factors moving forward.

Practical Guidance

Immediate steps to take:

  1. Seek immediate medical attention for all injured parties
  2. Report the incident to the police (road accidents) or relevant authorities (fire brigade etc.)
  3. Document the scene with photos and witness statements
  4. Get a hold of medical records relating to any pre-existing conditions
  5. Contact insurers as soon as you can and try your best to avoid long and detailed discussions concerning liability

Evidence to Collect:

  • Medical records showing any previous consultations about relevant conditions
  • Prescription histories and medication compliance records
  • Witness statements about previous medical episodes
  • Expert medical opinions on things relating to how foreseeable the accident was
  • Employment records showing where you disclosed the medical condition

Red Flags and the Need for Immediate Legal Advice:

  • Complex fault-finding issues, where there are multiple contributing factors
  • Disputes over whether medical conditions could have been foreseen
  • Insurance companies who deny your claim out of hand, based on pre-existing conditions
  • Cases involving safety-critical roles, such as professional drivers, pilots, surgeons etc.
  • Accidents resulting in serious injuries or deaths

Documentation to Keep Safe: Keep all medical records, incident reports, correspondence with insurers, and evidence of financial losses. It cannot be overstated just how important having the proper documentation impacts claim success rates.

When to Seek Professional Help

Complex cases require immediate legal expertise. This is especially true when:

  • Multiple parties share liability for the accident
  • Insurance companies dispute whether medical episodes were foreseeable
  • There are serious injuries which require substantial compensation claims
  • Professional obligations or licensing issues are involved
  • Evidence of prior medical warnings or ignored symptoms exists

Getting legal advice sooner rather than later prevents common pitfalls such as missing notification deadlines, accepting inadequate settlement offers, or failing to gather crucial medical evidence. Advice from the Motor Accident Insurance Commission, Queensland, is clear on this issue: that seeking legal guidance on this issue, for many, is in their ‘best interests’. 

Delays in seeking legal advice often result in weakened claims, lost or missing evidence, and missed opportunities for fair compensation.

Key Takeaways

  • Foreseeability determines liability: Known medical conditions creating foreseeable risks may result in liability, while sudden, unforeseeable episodes typically won’t
  • Evidence is crucial: Medical records, expert testimony, and proof of prior warnings can significantly impact the outcome of a claim
  • Time limits are strict: Three-year limitation periods for most claims, with shorter notification requirements for specific situations
  • Professional standards apply: Those in safety-critical roles (professional drivers, pilots, surgeons etc.) face more obligations to disclose medical conditions than the average citizen, meaning stricter liability standards
  • Multiple compensation avenues exist: Common law claims, workers' compensation, and TPD superannuation benefits may all apply
  • Early legal advice prevents problems: Complex cases involving accidents occuring due to medical episodes benefit significantly from immediate professional guidance. This ensures you are fully aware of your rights and the claim is managed most effectively
