“I accept that a failure to comply with the rules of service in CPR Part 6 should not be taken lightly … No reason has been put forward by the claimant as to why the rules were not followed. On the other hand, it is clear that the defendants’ solicitors received the Part 36 offer on 15 December 2020. Mr Seitler does not contend otherwise. No complaint was made about the method of service of the Part 36 offer until shortly before the hearing on 3 November. No suggestion has been made that there is any prejudice to the third defendant in the Part 36 offer having been sent by email rather than having been served in some other way, for example by post. In these circumstances, it would in my view be … “a triumph of form over substance” if the court were to make an order invalidating the Part 36 offer…”
The consequences of Part 36 can be punishing, but it is a separate question whether they are unjust. The justice of Part 36 is that decisions about litigation should be economically utilitarian: it actively discourages litigation on ‘points of principle’ by making litigation not fought on a commercial basis a high stakes activity.
