MATTHEWS v ACCIDENT COMPENSATION CORPORATION [2020] NZCA 449

Citation

[2020] NZCA 449
Court

Court of Appeal

The Court of Appeal granted special leave because the High Court declined to decide an arguable and important question of law — whether a later workplace injury or its treatment that aggravates a pre‑existing injury suffered when not an earner can constitute a cause of incapacity under cl 32 Sch 1 and s 103 — and that question was not clearly moot on the record; leave was granted to determine that legal issue and related factual causation on appeal.

Wytenburg v Accident Compensation Corporation (Entitlements)

Citation

[2019] NZACC 2
Court

District Court

On the balance of probabilities the evidence establishes that the appellant's medial tibialis posterior dysfunction and planovalgus deformity represent a gradual degenerative process predating 2009 with MRI and clinical signs noted in 2006 and 2009; any contribution from the 2009 lateral inversion injury is at best acceleration of a pre-existing condition and therefore excluded under s26, so the required surgery is not causally linked to the covered accident and the appeal must be dismissed.

MATTHEWS v ACCIDENT COMPENSATION CORPORATION [2018] NZHC 2769

Citation

[2018] NZHC 2769
Court

High Court

Special leave was granted because the case raises an arguable question of law on causation—specifically whether aggravation of a pre-existing condition can constitute a cause of incapacity under the Act and whether the District Court correctly applied the evidentiary burden—warranting appeal to the High Court.

Frame v Accident Compensation Corporation

Citation

[2015] NZACC 375
Court

District Court

On the balance of probabilities the C7/T1 condition is insufficiently shown to have been caused by the January 2005 accident; the weight of medical evidence and imaging indicates a longstanding degenerative process (with probable contribution from the 1989 incident) and the 2005 event at best aggravated pre-existing pathology rather than caused it, so ACC's decision to decline cover is upheld.

Stratful v Accident Compensation Corporation

Citation

[2015] NZACC 280
Court

District Court

The proposed surgery was intended to treat the ongoing osteoarthritis process of the facet joints rather than a covered lumbar strain or an injury caused by the accident; aggravation of pre-existing degenerative changes did not establish causation of an injury sufficient to entitle the claimant to funded surgery, therefore the appeal is dismissed.

Kumar v Accident Compensation Corporation

Citation

[2014] NZACC 32
Court

District Court

The Judge accepted the respondent's factual account that no significant forceful tipping occurred and preferred the opinion of Dr Christian over Dr Berry because it relied on a more accurate history of prior cervical symptoms; on the balance of probabilities the MRI findings and clinical history indicated pre-existing degenerative cervical and lumbar pathology rendered symptomatic by minor postural strain rather than a new cervical disc prolapse or a continuing new lumbar injury; accordingly the decisions declining cover for cervical prolapse and suspending ongoing lumbar entitlements were up…

Hart v Accident Compensation Corporation

Citation

[2013] NZACC 271
Court

District Court

On balance the court found sufficient evidence that physiotherapy treated the appellant's traumatic symptoms and ordered reimbursement for completed physiotherapy, but accepted expert evidence that the rotator cuff tears were chronic degenerative conditions likely pre-existing and merely aggravated by the accident, so cover for the tears was properly refused.

Thompson v Accident Compensation Corporation

Citation

[2013] NZACC 113
Court

District Court

The preponderance of medical evidence established significant pre-existing cerebrovascular disease (multiple lacunar infarctions) that explained the cognitive decline; any effect of the cardiac surgery was at most an aggravation of that underlying condition and, as a matter of law under the Act, aggravation of an underlying disease does not constitute a treatment injury under s32, so the appellant is not entitled to ACC cover.

Syme v Accident Compensation Corporation

Citation

[2012] NZACC 97
Court

District Court

Because the medical evidence did not establish that the 4 January 2010 fall caused a compensable injury or aggravated a pre-existing condition in a way that required ACC investigation, and no medical opinion linked the fall to long-term osteoarthritis, the Corporation's decisions declining entitlements were upheld and the appeal was dismissed.

Tata v Accident Compensation Corporation

Citation

[2011] NZACC 293
Court

District Court

On the balance of probabilities the judge found objective evidence (early x-rays showing advanced degeneration, MRI and arthroscopy findings, and specialist opinions) established that the appellant's ongoing pain two years after the accident was attributable to symptomatic degenerative osteoarthritic conditions rather than to persistent soft tissue injuries from the 2007 accident; therefore the respondent's suspension of entitlements was lawful and the appeal was dismissed.
