David Bain lawyers in Supreme Court

Lawyers for David Bain, who faces a retrial for the murder of five members of his family in Dunedin in 1994, will be in the Supreme Court today appealing an earlier court decision.

The appeal relates to a High Court decision on the admissibility of evidence. Today's arguments are expected to be suppressed.

Bain's lawyers are also awaiting a decision on an application for a stay of proceedings, following a hearing in the High Court at Christchurch.

Jury selection for the retrial has been set for March 6.

Meanwhile, Arthur Allan Thomas, who was wrongly convicted for the 1970s killings of a Waikato farming couple, has arrived in Christchurch to support Bain.

Mr Thomas, 71, was twice wrongly convicted for the murders of Harvey and Jeanette Crewe and spent nearly 10 years in jail. He was pardoned in 1979.

Mr Thomas told the The Press he contacted Bain after the Privy Council quashed Bain's convictions.

Mr Thomas said he had "concerns" about the jury selection process.

There have been calls for rarely used pre-trial examinations of jurors to sort out those who have prior knowledge of the case.
