I do not want to spend too much time on this. It is true that we have talked about it a number of times.
I think that if witness sends us a document a week in advance, the translation should be done as a matter of course, unless we run out of time. In the machinery of government, unless I am mistaken, documents are usually translated if they are sent in advance.
We do not want to put pressure on witnesses. We do not want to force them to write a brief in advance just because we want to have it. That is why we have all the services we do. The translation can be done afterwards; then we get the documents.
