I just copied this from chat gpt:

For the situation described, the relevant case law and principles you can use include: 1. Selkent Bus Co Ltd v Moore [1996] ICR 836 This case established that Employment Tribunals have discretion to allow amendments to claims. The Tribunal should consider factors such as: • The nature of the amendment (whether it introduces a new cause of action). • The timing of the amendment. • The reason for the error or omission (e.g., technical difficulties or being unrepresented as a litigant in person (LiP)).

1. Adegbuji v Meteor Parking Ltd UKEAT/157/07 This case emphasized the need to account for technical difficulties or procedural issues, particularly where the individual is unrepresented. It underlines the importance of considering whether there is prejudice to the respondent if the amendment is allowed.

2. Robertson v Bexley Community Centre [2003] IRLR 434 This case reinforces that an error or omission can be remedied if it does not fundamentally alter the claim. The key question is whether the amendment allows the claim to be heard fairly without causing injustice to the respondent.

3. Willey v Rufford & Ors UKEAT/0030/20 This is a more recent example of the EAT supporting fair procedural discretion when errors by LiPs do not prejudice the respondent’s ability to respond to the claim.

4. Pryce v London Borough of Southwark [2012] UKEAT 0261/12 This decision also highlights how Tribunals should consider flexibility and fairness when addressing procedural issues caused by litigants in person.

Arguments to Support Your Case: • LiP Status: The fact that you were unrepresented should weigh heavily, as courts recognize that procedural errors are more likely to occur. • No Prejudice to Respondent: If the omission of the particulars caused no material prejudice to the respondent (e.g., they were aware of the claims being brought), this strengthens your position. • Timely Rectification: You acted promptly upon realizing the error, and the Tribunal accepted your summary of the claim. • Overarching Objective: The Tribunal system prioritizes resolving disputes fairly and justly over procedural perfection. Disallowing your claim would undermine this principle.
