I think a lot of lawyers, myself included are at a bit of a loss over this one.
I get the sense that the level of mistakes and the frankly egregious misuse of the slip rule is almost unprecedented. There is a question over whether or not some of these corrections even stand because they are not within the permitted changes.
Rule 67 (the slip rule for ET) is for correction of clerical errors so
Acceptable - the correction of the name of “Not All Gays” as it was a clear misrecording of the name of the organisation and doesn’t impact the substance of the judgement
NOT Acceptable - removal of legal authorities and erroneous quotations such as the Forstater case and Lee v Ashers as these are foundational to the subsequent legal “analysis” in the judgement
Is the latest version of the judgement even valid if impermissible corrections have purported to be made?
