Kwan argued that as long as the names of those politicians remain secret, Canadians will lose trust in their elected officials, undermining MPs' ability to do their jobs.
"The report did not provide any names and as such all 338 members of this House, including those who have since left this chamber, are under a cloud of suspicion," Kwan said in June.
But Fergus ruled Monday that Kwan had failed to demonstrate "concretely" that keeping the names secret has impeded MPs' ability to carry out their duties.
"While I understand that findings presented in the NSICOP report are serious and appear to create suspicions about certain members, that in itself is not a basis to establish this question of privilege merits priority of consideration over all other House business," he said.
In order to be considered a "prima facie" violation of privilege, an issue must also be raised in a timely manner. In his ruling, Fergus pointed out that Kwan raised the issue two weeks after the NSICOP report was released.
