Can I make a second claim for lump sum compensation for permanent impairment?

The assessment of whole person impairment is now vitally important as it effects all entitlements to workers compensation under the Act.

The Workers Compensation Act allows an injured worker to make only one claim for lump sum compensation for permanent impairment if the claim was made after 19 June 2012. You cannot return and try to increase the assessment of whole person impairment once the claim has been made.
Often injuries deteriorate over time or an injured worker may require further surgery some years after the initial injury and this may increase the level of whole person impairment.

However, if you have already obtained an assessment of whole person impairment the Workers Compensation Act prevents you from returning and trying to claim an increase in the level of whole person impairment.

Medical expenses are payable for a maximum of either two or five years (after the last day on which you receive weekly payments of compensation) unless you have a whole person impairment of 21% or greater.

You are unable to make a claim for Work Injury Damages (a negligence claim against your employer) unless your whole person impairment is 15% or greater.

It is important not to make any claim for whole person impairment unless you are satisfied that your injury is unlikely to deteriorate further, or you are satisfied that you will exceed 21% whole person impairment.

If you exceed 21% whole person impairment this entitles you to ongoing payments of weekly compensation until retirement age (subject to the insurer conducting work capacity assessments every 2 years) and payment of medical expenses for life.  It also allows you to investigate whether you may have a claim for Work Injury Damages, that is, a negligence claim against your employer.

At Garling and Co we are starting to receive many enquiries from people who have seen a Lawyer and have had their whole person impairment assessed without considering that they only have one chance to make a claim for lump sum compensation.

If you have obtained an assessment of whole person impairment of 14% or less, this will prevent you from making a claim for Work Injury Damages and you can only receive weekly payments for a maximum of 5 years and medical expenses for a maximum of 5 years thereafter.

It is therefore a very important decision to make as to when to make a claim for lump sum compensation and how this decision will affect you rights to ongoing weekly compensation and medical expenses and whether or not you can make a claim for Work Injury Damages.

You should ensure that this decision is not made lightly and that your Lawyer discusses with you the ramifications of what will happen to your future entitlements to workers compensation should you not obtain an assessment of 15% or 21% whole person impairment.

Having said that, it may be possible to make a further claim for lump sum compensation for whole person impairment in certain circumstances.

Section 350(3) of the 1998 Act allows for a Certificate of Determination to be set aside or rescinded by the Workers Compensation Commission.

The Workers Compensation Commission considered in the matter of Samuel v Sebel that a Certificate of Determination may be set aside in consideration of the following:

  1. The Section gives the Commission a wide discretion to reconsider its previous decisions.
  2. While the discretion is a wide one it must be exercised fairly and with due regard to relevant considerations including the reasons for any delay in bring the application for reconsideration.
  3. One of the factors to be weighed in deciding whether to exercise the discretion is the public interest that litigation must not proceed indefinitely.
  4. Reconsideration may be allowed if there is new evidence that could not with reasonable diligence have been obtained at the first decision and is later obtained and that new evidence, if it had been put before an doctor on the first occasion, would have been likely to lead to a different result.
  5. A mistake or oversight by a legal adviser will not give rise to a ground for reconsideration.
  6. The Commission has a duty to do justice between the parties in accordance with the substantial merits of the case.

In taking all those matters into consideration the Commission may decide to rescind or set aside a previous Certificate of Determination assessing the level of whole person impairment if it is in the interest of justice to do so.

This may include cases where there has been a significant deterioration of a worker’s condition that was not foreseen previously or where a worker has sustained a subsequent consequential injury and would be entitled to additional lump sum compensation.

It is certainly a Section which will be looked at over the next few years to determine whether injured workers can return for a second assessment of whole person impairment under Section 350 of the Act.

I can’t thank Mr Garling and his team enough for the incredible support they provided throughout my case. From the very beginning, they showed genuine compassion, professionalism, and a strong... commitment to achieving the best possible outcome for me - and the result they achieved in the end was far beyond my expectations!What stood out most was their clear and prompt communication, customer-focused approach and kindness. At every stage, they made sure I understood what was happening and what to expect. This made a very difficult and emotionally challenging process a lot more manageable. Whenever I had questions or felt anxious they were responsive, patient, and reassuring.Thanks to Mr Garling, I felt empowered and confident navigating the complex, opaque and overwhelming workers compensation system. His dedication and expertise, along with the hard work of his entire team, helped me achieve an outstanding outcome.I cannot recommend Garling & Co highly enough, to anyone in need of personal injury legal assistance, and especially those dealing with a workplace injury / workcover.

I cannot speak highly enough of my experience with this workers Compensation team. When I first reached out, I was completely overwhelmed and unsure about the process. I hit rock bottom - unable to... return to work, struggling emotionally, and feeling like I had no direction. From the very beginning, the solicitors were nothing short of amazing. They were patient, understanding and incredibly supportive at a time when I needed it most. They took the time to explain every step in a way I could understand, never making me feel rushed or alone. Their professionalism was matched only by their compassion and that combination made all the difference.Throughout the entire journey, I felt heard, respected and genuinely cared for. They fought for me when I didn’t have the strength to fight for myself and thanks to their dedication, I was able to get the outcome I needed to rebuild my life. If you’re unsure, scared or feeling lost like I was, I can confidently say you will be in the best hands with this team. They helped me through one of the hardest chapters of my life, and I am truly grateful. I can’t thank or recommend Garling & Co Lawyers enough.read more

We initially contacted Matthew after my husband’s injury, he was so helpful and gave us all the information about my husband’s workers comp situation, he took the time and explained where my husband... was at with his claim and what we needed to do moving forward. This was even before we became a client which was refreshing and honest… Navigating a workers compensation claim is hard and really confusing, the team at Garling and co are so helpful and professional they really make the process easy and smooth!! We knew we could always call or email and ask questions about anything at any time. My husband doesn’t speak English fluently and Allison and Matthew catered to that in any ways possible.My husband was happy with the outcome of his claim, and he felt like he ended up with best possible outcome thanks to Matthew and the team.Thankyou Garling and Coread more

Matthew Garling and his team have provided incredible support and guidance throughout my MVA damages claim this year, and I can’t thank them enough for making this journey feel like such a breeze.... When I initially engaged Garling & co, I had no understanding of what was ahead. I was anxious and unsure about the process, while also navigating the physical challenges of my injuries. With assurance that my matter was being handled with high level of expertise, professionalism and integrity, I was able to focus on recovery instead. Throughout the process, Matthew and Allison have been honest, straightforward and efficient in all communication; being a supportive buffer in all dealings with the insurer, and consistently committed to a successful outcome. The outcome was excellent, and it is with huge relief and great thanks that I can put this matter behind me.
