A major court ruling has forced the National Disability Insurance Agency (NDIA) to fund a mobility scooter for a participant after a long legal battle, in a decision that experts say could reshape how disability supports are assessed under the National Disability Insurance Scheme (NDIS).

The judgement from the Federal Court is being described by legal advocates as highly significant because it clarifies how the agency must consider the complex and overlapping needs of people with multiple disabilities when determining what supports are “reasonable and necessary”.

The case centred on Victorian NDIS participant Lee Eastham, who challenged the agency’s refusal to fund a mobility scooter that he argued was essential for maintaining independence and participating in community life. After years of appeals and legal proceedings, the court ultimately ruled in his favour, ordering the NDIA to fund the device and cover the costs of the legal action.

A dispute that lasted several years

The case began in 2022 when Eastham, who lives in regional Victoria and lives with several disabilities, requested funding through the NDIS for a motorised mobility scooter costing about $7,300.

Eastham experiences hearing and vision impairments and also lives with physical health conditions that significantly affect his mobility. These issues make walking long distances extremely difficult and prevent him from driving.

He explained that a scooter would allow him to travel independently into town to carry out everyday activities such as shopping, attending medical appointments and volunteering with the State Emergency Service.

However, the NDIA rejected the funding request. The agency argued that the participant’s mobility difficulties were caused mainly by physical conditions rather than the vision impairment that originally qualified him for access to the NDIS.

Because of this reasoning, the NDIA concluded that the scooter did not meet the legislative requirement that NDIS supports must relate to the impairment used to access the scheme.

Appeal through the tribunal system

Eastham challenged the decision through Australia’s disability appeals system.

The matter was first brought before the Administrative Review Tribunal (ART), which reviews government decisions involving the NDIS. The tribunal ruled in favour of the participant, concluding that the scooter should indeed be funded.

However, the NDIA decided to appeal the tribunal’s ruling, taking the dispute to the Federal Court.

This further legal step significantly prolonged the case, turning what began as a funding request for a relatively modest assistive device into a complex legal battle.

Ultimately, the Federal Court upheld the tribunal’s decision and dismissed the NDIA’s appeal, confirming that the scooter must be funded.

Court clarifies how disability needs should be assessed

At the heart of the case was a key question about how NDIS law should interpret the relationship between a participant’s disabilities and the supports they require.

The NDIA argued that the impairment used to access the scheme must be the main cause of the support need. In Eastham’s case, the agency said his mobility problems stemmed from separate physical conditions rather than the vision impairment that made him eligible for the NDIS.

The Federal Court rejected this narrow interpretation.

Justice Lisa Hespe ruled that a participant’s qualifying impairment does not need to be the sole cause of their support needs. Instead, it is enough if that impairment contributes to the need for the support in some way.

The judgement emphasised that disability often arises from a combination of factors, including multiple impairments and environmental barriers.

According to the court, decision-makers must approach funding requests with “logic and common sense” and avoid overly rigid interpretations of the law.

A “whole-person” approach to disability

Legal advocates say the ruling reinforces the idea that disability should be assessed holistically rather than broken down into isolated medical categories.

Lawyers involved in the case argued that individuals cannot simply separate one disability from another when describing how their conditions affect daily life.

Instead, the court said decision-makers must consider the “whole person”, including how multiple disabilities interact and how external factors—such as access to transport—affect a participant’s independence.

For Eastham, this broader perspective was critical.

Because he cannot legally drive due to his vision impairment and because public transport in his area is limited, the mobility scooter was viewed as a necessary support that would allow him to participate more fully in community life.

Broader implications for NDIS participants

Experts say the ruling could have wide-ranging consequences for how the NDIA assesses funding requests across the NDIS.

Advocates believe it will make it harder for the agency to reject supports simply because a participant’s needs arise from multiple disabilities rather than a single qualifying impairment.

The decision also highlights the importance of considering environmental factors—such as location, infrastructure and transport availability—when determining whether a support is necessary.

For participants living in regional or rural areas, where public transport and services are often limited, this aspect of the judgement may be particularly significant.

Some legal experts believe the case could influence future decisions involving assistive technology, mobility aids and other equipment designed to improve independence.

Rising disputes within the NDIS system

The case also reflects a broader trend of increasing disputes between NDIS participants and the agency responsible for administering the scheme.

Recent years have seen a sharp rise in the number of appeals brought before the Administrative Review Tribunal.

Data shows the tribunal’s NDIS caseload grew significantly over the past year, and many of those cases resulted in the original NDIA decisions being overturned.

Advocates say this suggests growing tension between participants seeking adequate supports and the agency’s efforts to control costs within the rapidly expanding scheme.

The NDIS currently supports more than 760,000 Australians with disability and represents one of the largest social spending programs in the federal budget.

With annual costs expected to exceed $50 billion in the near future, the government has been pursuing reforms aimed at slowing the scheme’s growth.

Questions about legal costs

Another issue raised by the case is the financial cost of legal disputes between the NDIA and participants.

While the mobility scooter at the centre of the case cost just over $7,000, the legal proceedings extended across several years and multiple courts.

The Federal Court ultimately ordered the NDIA to pay Eastham’s legal costs in addition to funding the scooter.

Legal experts say cases like this can cost tens of thousands of dollars, raising questions about whether prolonged litigation represents an efficient use of public resources.

Advocacy organisations argue that resolving disputes earlier—before they reach court—could save both participants and the government significant time and expense.

A personal victory with wider impact

For Eastham, the decision represents more than a legal victory.

The mobility scooter will allow him to travel more easily within his community and reduce his reliance on others for everyday activities.

He has said the device will greatly expand his independence and enable him to participate more actively in local life.

At the same time, advocates believe the case could benefit many other NDIS participants who face similar challenges when seeking funding for assistive equipment.

By clarifying how the law should interpret the relationship between disability and support needs, the ruling may influence future decisions across the entire NDIS system.

A defining moment for NDIS decision-making

The Federal Court judgement arrives at a time when the NDIS is undergoing major reform aimed at improving sustainability and fairness within the scheme.

As policymakers continue to redesign parts of the program, the case highlights the importance of ensuring funding decisions remain grounded in the real-world experiences of people with disability.

For many advocates, the ruling sends a clear message: disability support decisions must consider the complexity of people’s lives rather than relying on rigid categories.

If applied consistently, the judgement could shape how the NDIA interprets the NDIS Act and evaluates participant needs for years to come.
