XYZ v Various (Including Transform Medical Group (CS) Ltd and Spire Healthcare Limited) & Ors

Joinder is permissible where the proposed issue is connected to matters already in dispute, even if the existing party has no extant cause of action against the proposed new party. The connection must be real and material: the issue should be central to resolving the existing dispute, not merely raise similar questions or potentially produce consistent findings. A general case-management power cannot be used to circumvent specific joinder rules. A party cannot ordinarily join an opponent’s insurer merely to establish in advance the insurance available to meet a possible liability.

Travelers Insurance Company Limited applied to join Amlin Corporate Members Limited as a sixth party and sought a declaration concerning insurance held by Clover Leaf Products Limited. The application arose in group litigation concerning defective breast implants. Transform had insurance with Travelers, while Clover Leaf, against which Transform had brought Part 20 claims, had insurance with Amlin.

Travelers argued that Amlin should participate in an impending insurance trial to promote settlement and avoid inconsistent decisions. Amlin argued that there was no present dispute with Clover Leaf or Amlin and that the application was premature. The central issues were whether joinder was available under CPR 19.2, whether the claim could be brought under CPR 20.7 and retained under CPR 20.9, and whether CPR 3.1(2)(m) supplied an independent basis.

1. Application dismissed. Amlin was not joined and the declaration was not permitted.

2. Under CPR 19.2(2)(a), the matters in dispute in the proceedings could include disputes between defendants and their insurers, as well as the main claims and Part 20 claims. Nevertheless, that limb did not apply because all matters in dispute could be resolved without adding Amlin.

3. Under CPR 19.2(2)(b), an issue involving the proposed new party need not amount to an existing cause of action. The issue must, however, be connected to the matters in dispute. The authorities treated that connection as requiring an issue central to, or materially involved in, the resolution of the existing proceedings.

4. The proposed declaration concerned the scope of Amlin’s separate insurance of Clover Leaf. It was not connected with the claimants’ claims, the Part 20 claims against Clover Leaf, or the existing disputes between defendants and their insurers. Similar policy questions and the possibility of consistent conclusions did not create the required connection.

5. The same conclusion applied under CPR 20.9(2)(a) and (c). The proposed additional claim was not connected with the claimant’s claim or the subject matter of the proceedings.

6. Although the Civil Procedure Rules could be applied flexibly in furtherance of the overriding objective, CPR 3.1(2)(m) could not be used to circumvent the specific rules in CPR 19 and Part 20. Establishing in advance the amount of insurance available from Amlin was not a case-management matter.

First-instance decision. No appeal history is stated in the judgment.
