Parliamentary privilege is what protects the separation of court, the Crown and the legislature in the proper functioning of a constitutional system, said Susan Keenan, a lawyer for the province.
“It’s important that the privilege be protected when it is under threat,” Keenan said. “If not, harm is not only irreparable, but it is cumulative.”
“It puts the premier and the deputy premier in the intolerable position of having to assert their privilege and be potentially faced with contempt proceedings,” said Darrell Kloeze, another provincial lawyer.
The province argued that not granting a stay would have a chilling effect on all legislative bodies, leaving politicians open to possible fines, contempt of court or imprisonment if they choose not to testify in any proceeding.
Allowing the summons would erode all parliamentary privileges, Keenan said. Those include exemption from jury duty and freedom of speech in the house while enjoying complete immunity from prosecution or civil liability, and exemptions from being subpoenaed to appear in court as a witness.
The judge hearing the arguments said he was struggling with the idea that the summons itself would be invalid, given the commission has the same summoning power of a provincial Superior Court.
He noted that parliamentary privilege resulting in immunity to being summoned to a criminal or civil court is a long-standing privilege. But Fothergill said this case will turn on whether he finds that privilege applies to public inquiries.
The province pointed to a 2005 case in Federal Court, which held that parliamentary privilege applies to public inquiries.
Commission lawyer Doug Mitchell argued no single case before has determined if parliamentary privilege applies to inquiries. He argued that privilege must be determined on a case-by-case basis.
“It is the role of the court to determine the scope (of the privilege), you don’t just accept parliament’s assertion,” Mitchell said.
There is no blanket rule that provides immunity to sitting politicians in every single case, he said, adding that several courts have disagreed with parliamentarians asserting various types of privilege.
“I think that’s pretty speculative at this point,” he said.
“I don’t think it constitutes irreparable harm to make a difficult choice,” Mitchell said. “It’s dressed up in constitutional language, but it’s not the type of irreparable harm that a court is entitled to insist on.”
