Citation: [2024] EWHC 560 (Ch)
Judgment on


The case of Paul O’Boyle (Trading as Viridian) & Anor v Mary Viven Wallis provides a thorough examination of the legal principles concerning amendment of pleadings, identification of parties in a lawsuit, and the interpretation and application of the Civil Procedure Rules (CPR) in relation to a partnership that has been dissolved. The case reflects the significant discretion afforded to the courts in managing the amendment of pleadings, the importance of concise and coherent particulars, and the proper procedure for litigating claims related to a partnership.

Key Facts

Paul O’Boyle, trading as Viridian, brought claims against Mary Viven Wallis, alleging wrongful conversion of goods stored in units and containers. The initial particulars of claim (POC) contained several deficiencies, including unclear claims and improper identification of parties. After a series of amendments and strike-out applications, the High Court considered whether additional proposed amendments should be allowed.

Key issues related to:

  • Whether the proposed amendments introduce new claims or provide further particulars of an existing claim.
  • The procedural implications of a partnership’s dissolution upon the claims asserted.
  • The bar for whether an amendment should be permitted or struck out.

The dispute encompassed:

  1. Claims against Wallis as a partner in Woodmancott Enterprises.
  2. The correct interpretation of which claims survived following the dissolution of the partnership.
  3. The validity and sufficiency of the claims related to the contents of containers and units, including moulds.

Several legal principles were engaged in this case:

  1. Amendment of Pleadings (CPR 17): It’s crucial for amendments to have a real prospect of success and the courts must balance the potential injustice of permitting or refusing an amendment.

  2. Striking Out and Summary Judgment (CPR 3.4 & CPR 24): Claims must be realistic, not fanciful, carrying a degree of conviction.

  3. Identification of Parties in a Lawsuit: Proper procedure for bringing claims against partnerships or individual partners, especially in the context of a dissolved partnership.

  4. Principles of Pleading (CPR 16): Pleadings must be concise, only containing material facts and not evidence nor arguments.

  5. Overriding Objective (CPR 1.1): Cases must be dealt with justly and at proportionate cost, which means ensuring that they’re dealt with expeditiously and fairly.

  6. Payment into Court as a Condition: This may be imposed as a sanction for weakness or improbability of claims, reflecting past failures to comply with rules or orders.


The court conducted an in-depth analysis and made several critical determinations:

  1. Claims against Mrs. Wallis as a former partner of Woodmancott Enterprises were allowed to proceed, not recognized as new claims despite the death of the other partner and subsequent dissolution of the partnership.

  2. The court required further amendments to the proposed Re-Amended Particulars of Claim (RAPOC) to ensure they were clear, concise, and consistent with the legal standards of pleading.

  3. The proposed amendments were subject to close scrutiny, and the claimant was given further opportunity to refine their case. The court signalled that future permissions to amend might be conditional on a payment into court as a means of effective case management and as a sanction for the historical deficiencies in pleadings and litigation conduct.

  4. The legal principles surrounding the allowance of amendments and striking out of claims were substantiated by references to earlier case law and legal texts.


The judgment in O’Boyle & Anor v Wallis illustrates the intricate nature of civil litigation, highlighting the critical role of appropriate pleading and reinforcement of the conditions under which litigants are permitted to amend claims. The case serves as a cautionary tale for litigants and their legal representatives about the necessity of attention to detail and procedural compliance when drafting and amending particulars of claim. The court’s decisions reflect a commitment to procedural fairness while emphasizing the necessity of efficient case management, adhering to the ideals of the overriding objective to ensure timely justice.
