I'd like to hear from the experts on this but my initial thoughts are the following. It basically blurs the distinction between an authorization and an extension because the purpose of an extension of a ministerial authorization is to ensure that the CSE can continue in the event of a commissioner's absence or incapacity. An extension doesn't provide CSE with any new authority. It simply continues what was already previously reviewed and approved by the intelligence commissioner. I'd just like to have the experts confirm that this is in fact a correct understanding.
