It is surprising that there are not more of these cases. I suppose the issue is not whether the statement is defamatory but whether or not serious harm was caused as a result of the tweet.
The Judge also advised Solicitors to be aware of the problems arising from early deletions “I am not able to attribute responsibility for that on the basis of the evidence, and I do not. What I can say is that this highlights in the Twitter context the responsibility of a litigant to retain and preserve material that may become disclosable, and the responsibility of a solicitor to take reasonable steps to ensure that the client appreciates this responsibility and performs it”.
The Judgment also makes clear that Twitter is not fair game and anything goes.
