Cartridge case fit-up denied to the end

The police officer accused of planting a cartridge case in the Crewe double-murder inquiry went to his grave denying he fitted up Arthur Allan Thomas, who was twice convicted then pardoned over the homicides.

Inspector Bruce Hutton also refused to accept any concerns about the item of key evidence in the two trials over the 1970 murders, despite overwhelming evidence to the contrary. The insistence by Mr Hutton that the cartridge case -- known as exhibit 350 -- was a genuine discovery flies against the royal commission of inquiry findings in 1980.

That found that not only was it false evidence but that it had been planted by Mr Hutton and another officer, Detective Len Johnston.

David Jones, QC, who had independent oversight of the police review, found the cartridge was false evidence "beyond reasonable doubt".

Documents released through the Official Information Act show Mr Hutton was interviewed by the officers leading the review in January 2012. He died 15 months later in April 2013. The Thomas family have asked why he was allowed to die without being prosecuted. The interview was the first formal occasion on which Mr Hutton was questioned about the planting allegation since the 1980 royal commission hearings.

Detective Superintendent Andy Lovelock confirmed the interview, saying the meeting "included discussion of exhibit 350".

"Mr Hutton believed there was no issue regarding the integrity of the exhibit or the way it was found."

Mr Lovelock confirmed receiving "complaints from [Arthur Thomas' brother Des] Thomas in October 2012".

He said the issues raised by Mr Thomas about the cartridge case had been "addressed in detail" in the report. The section he nominated repeated the finding of the Solicitor-General of the time that it would not have been possible to prosecute Mr Hutton -- a finding Mr Jones' oversight report contradicted this year.

The section also included dismissal of other complaints by Des Thomas, which he had addressed to the commissioner and asked be treated as formal criminal complaints. Mr Thomas told the Herald that Mr Jones' report into the investigation showed Mr Hutton should have been charged.

Peter Williams, QC, who represented Arthur Thomas after the convictions until he was pardoned, said the cartridge case was a "fundamental weapon of the prosecution". He said Mr Hutton's position over the discredited piece of evidence was not surprising.

"It's not unusual for criminals to be in a state of denial. Some stay that way all their lives.

"It should have at least gone to the courts. He could well have been acquitted ... You would have thought the charge would be brought."

Commissioner Mike Bush would not be interviewed about exhibit 350. He had earlier removed himself from the review process after delivering a eulogy at Mr Hutton's funeral in which he described it as a "tragedy and irony that a man of such character" should be accused of dishonesty.

In a statement, Mr Bush said the police review included criticism of their position on the planted cartridge case.

"Police accept that failure to reinvestigate this case earlier resulted in adverse public speculation over the years."

He said public faith remained strong, surveys showing growing numbers of Kiwis have high or very high confidence and trust in police.
