As my colleague from Winnipeg Centre noted, any solicitor-client privilege here can be waived by the government, and arguably the real privilege here is that which is actually owed to the Parliament, which itself may be validly asserting its parliamentary privileges and authority in seeking such documents.
Comme l'a dit mon collègue de Winnipeg-Centre, le gouvernement peut renoncer à n'importe quel privilège avocat-client, et celui qui a vraiment un privilège ici, c'est sans doute le Parlement, qui, en exigeant ces documents, affirme légitimement ses privilèges et son pouvoir.
