Probably what you'll have in the case of somebody who is injured is that they will have an initial treatment. They will go see their doctor. The doctor will assess them, treat them for their illness, their particular injury. Those will all be part of the general treatment provision. There will be X-rays, different tests done.
If those tests, those examinations, those reports were done in the context of a treatment for a medical purpose, those are exempt now, and those will continue to be exempt.
If, in a court case, they asked for those types of reports, assessments, that were done in the context of the treatment, those will continue to be exempt, and those have been exempt.
If, however, something is done subsequently, and it is done after those initial treatments, and it is done simply and solely for the purpose of the legal proceedings, the insurance proceedings, then those would not be tests or examinations or reports—for example, some of the items you've listed—that would have been done for a health care purpose, and those would be subject to GST.
