I have a contact who has been talking with the barrister who first spotted this issue of the wording of the contract - I will ask him for more info for you.(posted 8019 days ago)Note that the time-limit for receiving a response to a SARN is 40 days not seven. Therefore do not impose or apply a seven day time- limit - as given in the post below - to SARN requests.
You may be able to impose a seven day time limit as part of discovery/disclosure but I think that is more often done by setting a mutually agreed date to exchange documents.
You may impose a seven day limit if you are requesting copies of docs as part of negotiations that are taking place before anyone has issued a court claim (formerly called a writ).
