 Gibli, who had acted as presiding judge, prosecutor, interrogator, witness and record-keeper in Tobianski's court martial, also appeared as a witness for the prosecution in Be'eri's trial.In his memoir, David Kron wrote that despite the official investigation, he was convinced that Tobianski had been guilty and that Be'eri had the full authority to act the way he had.Later Shabtai Teveth placed the fault with Gibli's overbearing ambitions and manipulation, personal traits that led to the Lavon affair.
