Limitations & cautions
CPR 31.20 limits the harm of a slip, but it is not a cure-all. The court may still permit use of an item in some cases. Treat the rule as a backstop, not a substitute for careful review, and confirm each flag before anything goes out.
Frequently asked questions
What does CPR 31.20 do?
Where a privileged document is inadvertently disclosed, CPR 31.20 says the other party may use it only with the court's permission. It underpins a clawback of a mistaken disclosure.
Does local processing help the privilege claim?
Yes. Keeping data in-house shows reasonable steps to protect privilege and cuts the chance of a third-party leak in the first place.
Can I tag privileged passages as I go?
Yes. Privilege tags track which items you handled, which helps document your process.
