Bennett also ruled that lawyers for David Basi, Bob Virk and Aneal Basi can obtain emails related to Pilothouse for 14 other current or former BC Liberal MLAs, including former Deputy Premier Christy Clark.
But a defence application that Bennett remain as judge for the trial of the three aides was put off until July 20.
In an interview after the short hearing Michael Bolton, representing David Basi, said the defence was pleased with the ruling.
"The judge ruled that the email records related to the divestiture of BC Rail and contact with lobbyists Erik Bornmann, Brian Kieran and Jamie Elmhirst be disclosed to the defence," he said.
"She ordered communications on Mr. Campbell's email account on Pilothouse be disclosed and those with any of the lobbyists," Bolton added.
"This result means the defence will get a large part of the emails it was seeking for 2002 to 2004," Bolton said. "It also means we may be in a position to bring an application for some of the records that were not disclosed today."
Here are dates currently scheduled for pre-trial hearing applications:
July 16-17 - Continuation of defence application for executive council 3rd party records, with a submisison from BC government lawyer George Copley.
July 20 - Hearing on a defence request that Justice Elizabeth Bennett continue as the trial judge despite her elevation to the BC Court of Appeal. Special Prosecutor Bill Berardino has asked that she be replaced.
July 21-22 - Defence application for non-compliance order over failure to disclose material previously ordered released by Bennett.
July 23 - Continuation of the defence application for the business records of Patrick Kinsella and the Progressive Group companies.
August 18-20 - Continuation of Kinsella application if necessary.
Still unknown is whether the Supreme Court of Canada will issue ruling on the secret witness appeal by Special Prosecutor Bill Berardino. The Court does not usually release decisions of this nature during the summer months.
