When the National Disability Insurance Scheme (NDIS) Act 2013 talks about a disability, one of the first hurdles is whether an impairment is 'permanent or likely to be permanent'. This sounds straightforward, but its legal meaning is much more specific than how we might use the word 'permanent' in everyday conversation. It's not just about an impairment being long-lasting or chronic.

The core of this definition is found in Section 24(1)(b) of the Act. But to truly understand it, we need to look at the 'Becoming a Participant' Rules, specifically Rule 5.4. These rules clarify what Parliament intended. They state that an impairment is considered permanent only if there are no known, available, and appropriate treatments that are likely to remedy it.

This leads to a crucial question: What does it mean to 'remedy' an impairment? The law makes a distinction between a remedy and a cure. A treatment doesn't need to offer a complete cure to be considered a remedy. If a treatment can alleviate the functional impact of an impairment, even without removing the underlying condition, it might be considered a remedy in the eyes of the National Disability Insurance Agency (NDIA).

For a treatment to be considered, it must be 'known, available, and appropriate'. Let's break that down. 'Known' means it's a generally recognised evidence-based clinical treatment. 'Available' means it's practically accessible to the person in their location. A cutting-edge trial in another country, for example, wouldn't be considered available.

'Appropriate' is more nuanced. It takes into account the individual's circumstances. A treatment might be clinically available, but it could be inappropriate due to significant risks, potential side effects, or a person's other health conditions. The NDIS cannot compel a person to undergo treatment, but it will assess whether the refusal of an appropriate treatment is reasonable when deciding if an impairment is permanent. This assessment is a key part of the access request process.

Ultimately, the legislation is trying to establish that the impairment is 'enduring'. This is the legal system's way of saying that the condition has been, and is likely to remain, a long-term feature of a person's life that impacts their functional capacity.

An impairment isn't required to be static. Many conditions fluctuate, with periods of greater and lesser severity. The key is that the underlying condition itself remains. For example, a person with Multiple Sclerosis may have periods of remission, but the underlying neurological condition is permanent. The focus is on the long-term prognosis, supported by medical evidence. This is why a comprehensive medical history and reports from treating professionals are so vital for an NDIS application.

By focusing on the lack of a likely remedy through available and appropriate treatments, the NDIS Act establishes a high but clear threshold. It ensures that the scheme is directed towards those with lifelong disabilities that significantly affect their ability to participate in the community. Understanding this definition is the first step in successfully navigating the NDIS access requirements.

Time to check your understanding of these key legal definitions.

The distinction between a 'remedy' and a 'cure' is a fine but important line in disability law, ensuring that support is directed where it's truly needed for enduring conditions.
