Monsieur Lareau and Mr. Cockfield, I'll ask my question in English this time.
There is such a thing as privilege between attorney and client. There is such a thing as privilege between a doctor and a patient. There is such a thing as privilege between, say, a member of the clergy and the faithful.
Is there such a thing as privilege between a tax accountant or tax lawyer and a client? Regardless of the answer, should there be?
