Williams v Wilkinson [2026] EWHC 1088 (KB) (08 May 2026)

Permission to amend the Particulars of Claim is refused because the application is very late, would cause loss of the trial date, lacks a good explanation for the delay, and the proposed amendment fails to address obvious factual issues, leaving its prospects of success uncertain. The balance of injustice weighs heavily against granting permission, given the prejudice to the Defendant and the court system, and the Claimant's failure to properly analyse causation earlier.

Procedural Posture

Clinical Negligence Claim / Application for Permission to Amend Particulars of Claim and Rely on Further Evidence Before Trial

Legal Issues

  1. 1 Whether to grant permission for a very late amendment to the Particulars of Claim in a clinical negligence case
  2. 2 Whether the proposed amendment has a real prospect of success or is bound to fail
  3. 3 Whether the lateness of the application and its impact on the trial date justifies refusal of permission

Ratio Decidendi

Permission to amend the Particulars of Claim is refused because the application is very late, would cause loss of the trial date, lacks a good explanation for the delay, and the proposed amendment fails to address obvious factual issues, leaving its prospects of success uncertain. The balance of injustice weighs heavily against granting permission, given the prejudice to the Defendant and the court system, and the Claimant's failure to properly analyse causation earlier.

Court Disposition

Permission to amend refused

Orders

  • Application for permission to amend Particulars of Claim is dismissed
  • Application for permission to rely on further evidence is dismissed
