Cass's report was accepted by the police as being accurate, and in his 1983 autobiography McNee wrote "when all the evidence was assembled it showed that Blair Peach had died from a blow to his skull. The evidence pointed to the fact that the blow had been struck by a police officer." Cass finished the investigation in February 1980; 30 investigators had worked for 31,000-man-hours during his enquiries. He finished his initial report on 12 July 1979, which was sent to the DPP, who, while praising the work he had done, stated that "there was insufficient evidence to justify a prosecution". The inquest reopened a week later. Both Burton and the lawyers representing the Metropolitan Police were given copies of Cass's report, but refused to provide copies to the lawyers representing the Peach family or those representing the Anti-Nazi League. Burton used Cass's report to determine which witnesses to call and which to ignore. Michael Dummett, Wykeham Professor of Logic at Oxford University, examining the case for the National Council for Civil Liberties, observes that as only the coroner and police lawyers had copies of the report, "it was impossible for anyone ... [else] to obtain a complete picture of the evidence". The question of whether the family were allowed to view the reports was taken to a Divisional Court, who ruled that as the report was the property of the police, they had the right to withhold it. Legal counsel for the Peach family requested that the inquest be held in front of a jury, which Burton rejected; the inquest was again adjourned. The High Court rejected a challenge to overturn Burton's decision, which then went to the Court of Appeal where Lord Denning stated that the inquest should reconvene in front of a jury. In early 1980, sections of the Cass report were published in "The Leveller" (January 1980) and "The Sunday Times" (March 1980). Details included in both publications were the names of Murray, White, Freestone, Richardson and Scottow. The latter publication indicated that the decision by the DPP not to prosecute the policemen "left the investigating officers in the invidious position of appearing party to a cover up, should their report ever become public". In April 1980—the one-year anniversary of Peach's death—members of the group "Friends of Blair Peach Committee" picketed outside police stations holding posters that named the six members of SPG Unit 1-1 and the words "Wanted for the murder of Blair Peach". The inquest reconvened on 28 April 1980, and was expected to last several weeks.
