Blog › DVA claims
Every DVA claim is decided against a Statement of Principles. Here is what an SoP actually is, how factors are proved, and why the wording of your medical evidence decides the outcome.
Veterans are often told their claim was refused because "there wasn't enough evidence". That is rarely the whole story. In almost every case the real answer is narrower and more useful: the evidence did not engage a Statement of Principles factor.
A Statement of Principles (SoP) is a legislative instrument made by the Repatriation Medical Authority, an independent body of medical and scientific experts. There is one for almost every condition a veteran is likely to claim — well over 300 of them — and each sets out, exhaustively, the circumstances capable of connecting that condition to service.
The delegate deciding your claim does not weigh up whether service "probably" caused your condition in a general sense. They ask a much more specific question: does the evidence show that one of the factors listed in the relevant SoP was met, and that it was met because of your service?
You can read the full text of every current SoP in our SoP Library.
Most conditions have two SoPs, and which applies depends on the nature of your service.
The two versions of an SoP are not identical — the reasonable hypothesis version typically contains more factors, and the thresholds inside them are often easier to meet. Citing the wrong one, or citing only one when both could apply, quietly costs veterans claims every week.
SoP factors are precise, and that precision cuts both ways. A factor might require a specified level of noise exposure over a specified period, or a particular kind of trauma to a particular joint, or a diagnosed condition existing before the onset of the claimed one.
The consequence is that a supportive letter saying "in my opinion this is related to his Army service" does nothing. It does not name a factor, so there is nothing for the delegate to accept or reject. A useful report does the opposite: it names the SoP, works through each factor in turn, and states plainly which are met and which are not met, against the clinical entry that proves it.
Once you understand that the SoP is the test, the shape of good evidence becomes obvious. Every Diagnostic Assessment we write follows the same structure: the diagnosis, the relevant SoP for both standards of proof, a referenced timeline drawn from the service record, and each factor argued to met or not met with the page reference behind it.
Nothing is left for the delegate to infer, because anything they have to infer is something they can decline to infer. If you would like to see what that looks like in practice, our Claims Library holds 319 example Diagnostic Assessments across 265 conditions.
SoPs also cover situations veterans rarely think to claim:
Each of these has its own pathway inside the SoP framework, and each is regularly missed.
The Repatriation Medical Authority publishes them all, and we mirror the full text in our SoP Library so you can read the factors that apply to your claim.
A small number of conditions have no SoP. Those claims are decided on the general evidence rather than against listed factors, which makes the quality of the medical reporting even more important.
Yes. The RMA reviews and reissues SoPs, and a factor that did not exist when you were refused may exist now. That is one of the reasons an old rejection is worth revisiting.
Ideally, but most GPs have never seen an SoP — there is no reason they would have. That is the gap a medicolegal practice fills.

The expert in veterans’ medicolegal medicine — Expert DVA Doctor.








Dr Thomas Perkins is the founding doctor at the Veterans Health Centre in Ipswich, Queensland, and the leading expert in veterans’ medicolegal work in Australia. He has spent over 13 years working exclusively with current and former Australian Defence Force members — treating conditions, writing reports, and navigating the DVA system alongside them.
With 100,000+ DVA claims submitted and over 2,000 Permanent Impairment Assessments completed, Dr Perkins brings a depth of experience that simply cannot be replicated from a textbook. He understands the Statements of Principles, the GARP tables, the imaging that proves what a physical examination alone cannot — and the difference that a properly written report makes at every level, from initial liability through to the VRB.
Every chart review, every diagnostic assessment, and every impairment rating is personally overseen by Dr Perkins. If you’re looking for a doctor who knows veterans medicine inside and out, you’ve found the right clinic.
