MEDIA RELEASE – FOR IMMEDIATE PUBLICATION
MARK EDWARD LUNDY v THE QUEEN
CA232/2015,  NZCA 410
This summary is provided to assist in the understanding of the Court’s judgment. It does not comprise part of the
reasons for that judgment. The full judgment with reasons is the only authoritative document. The full text of the
judgment and reasons can be found at www.courtsofnz.govt.nz.
Mr Lundy has appealed against his conviction for the murders of his wife Christine and daughter Amber, aged seven, at
the family home in Palmerston North early in the morning of Wednesday 30 August 2000. Mr Lundy was first convicted in
2002 but the convictions were set aside on appeal to the Privy Council. He was tried again in 2015 and those are the
convictions under appeal.
The principal issues advanced on appeal related to the probative value and prejudicial effect of scientific evidence
relied on by the Crown to link Mr Lundy to the murders. Mr Lundy also argued that there were significant omissions from
the trial Judge’s summing up, and that the retrial was an abuse of process because of substantial changes to the Crown
case compared with that advanced at the first trial.
The Court of Appeal has upheld Mr Lundy’s convictions, rejecting all but one of the grounds for his appeal.
For reasons that the Court explains, it has decided that scientific evidence relied on by the Crown based on mRNA
tracing was inadmissible. notwithstanding that it had been ruled admissible pre-trial by the High Court, a ruling
confirmed by this Court on pre-trial appeal. However, the Court rejected Mr Lundy’s challenge to the admissibility of
the immunohistochemistry (IHC) evidence which was advanced by the Crown to establish the presence of central nervous
system tissue (CNS tissue) on two stains on Mr Lundy’s shirt, noting that all of the experts called at the retrial
agreed that the IHC methodology and results showed that the tissue was CNS tissue.
The Court of Appeal’s ruling that the mRNA evidence should have been excluded required the Court to consider whether Mr
Lundy would have been convicted notwithstanding the admission of this evidence.
Because Mr Lundy was retried on an indictment first presented in February 2002, the consideration of that issue took
place under the proviso to s 385(1) of the Crimes Act 1961, as if it had not been repealed. Section 385 of the Crimes
Act provides that the Court must allow an appeal if, amongst other things, it is of the opinion that there has been a
miscarriage of justice. However, that is subject to the proviso, which states:
… provided that the Court of Appeal or the Supreme Court may, notwithstanding that it is of opinion that the point
raised in the appeal might be decided in favour of the appellant, dismiss the appeal if it considers that no substantial
miscarriage of justice has actually occurred.
The question of whether the proviso should be applied involves two considerations. First, the Court must feel sure of
the guilt of the accused in the sense that, on a review of all the admissible evidence, conviction was inevitable.
Secondly, the Court must be satisfied that the trial was fair, with the result there had been no breach of the right to
a fair trial guaranteed by s 25(a) of the New Zealand Bill of Rights Act 1990.
Therefore under the proviso the Court was required by its terms to consider whether, notwithstanding the determination
that the mRNA evidence was inadmissible, the appeal should nevertheless be dismissed on the basis that no substantial
miscarriage of justice has actually occurred. A number of specific issues were raised for Mr Lundy which it was said
raised a reasonable doubt. Having considered these issues the Court has determined that none of them, on their own or
collectively, undermine the strength of the Crown case. The Court is sure of the guilt of Mr Lundy notwithstanding the
rejection of the mRNA evidence. It is also satisfied the trial was fair. Therefore, the Court has decided that the
proviso should be applied and the appeal dismissed.
