Generally, a claim for the acceptance of liability under the MRCA can be made in respect of:

  • clinical onset of a condition (see paragraphs 27(a), 27(b), 27(c), 27(e), and subsection 29(1)); and
  • aggravation of a pre-existing condition (see paragraph 27(d), subsection 29(2), and section 30).

The transitional provisions operate with different rules depending on whether they are being applied to a claim for clinical onset or a claim for aggravation.
