Amending List of Issues at ET Preliminary Hearing — is Selkent + Abercrombie the right combination
I'm a litigant in person in an Employment Tribunal claim (whistleblowing detriment + automatic unfair dismissal). I have a Preliminary Hearing coming up where I'll be applying to amend the List of Issues to add several new issues/sub-issues.
My approach has been to rely on two cases together:
- Selkent Bus Co Ltd v Moore [1996] ICR 836 — the standard test (arguability, prejudice to either side, overall balance of justice).
- Abercrombie v Aga Rangemaster [2013] EWCA Civ 1148 — to argue that the focus shouldn't be on whether an amendment is formally a "new cause of action," but on the practical extent of new factual/legal enquiry it requires, and specifically whether the other side already had the underlying facts or a fair opportunity to investigate them.
Most of the amendments I'm seeking are based on documents the Respondent itself produced (through disclosure), or on its own pleaded case, rather than on anything new to them. My argument is that under Abercrombie, there's no real prejudice because they already had the material — even though the amendments introduce new legal characterisations.
A few questions for anyone with ET or civil litigation experience:
- Is combining Selkent and Abercrombie like this actually sound, or is Abercrombie more of an EAT/appellate gloss that doesn't do much extra work at first-instance Tribunal level?
- Are there other cases commonly cited alongside Selkent for "the respondent already had the facts, so no real prejudice" arguments that I should also have ready?
- In practice, do Employment Judges find this kind of "no new enquiry" argument persuasive, or does lateness/volume of amendments tend to dominate regardless of whose documents they came from?
- Any common pitfalls with relying on Abercrombie specifically that I should be aware of before a judge tests it?
Thank you
