In addition, as the minister indicated, going with the record of the case procedure as opposed to first-person affidavit, there may be some situations where one may be able to protect the identity of a witness in the record of the case, while in the course of a first-person affidavit, you have to identify yourself.
En outre, comme l'a dit la ministre, le recours au document du dossier plutôt qu'aux affidavits à la première personne permet de mieux protéger l'identité d'un témoin puisque, dans un affidavit, il faut s'identifier.
