Consolidation of Cases: A Closer Look

Multiple cases with overlapping subjects and shared parties are not rare in the legal field.

The court system addresses such instances through the consolidation of cases.

Consolidation involves combining two or more separate legal actions into one proceeding.

This process is nuanced, and not all cases are suitable for consolidation.

To understand this topic better, let's review the case of Newbey v Smoothy [2023] WADC 45, where the plaintiff sought to consolidate two actions.

In Newbey v Smoothy, the plaintiff, Mrs Helen Newbey, attempted to consolidate action CIV 4983 of 2022 with CIV 1954 of 2020, under Rule O 83 r 1 of the Rules of the Supreme Court 1971 (WA). She also requested that CIV 1954 of 2020 be designated as the lead action. The defendants opposed this application.

In this case, the court decided against the consolidation of actions but allowed for the two actions to be heard together. The court emphasized the difference between consolidation and joint determination of actions, a case management technique referenced by Justice Lundberg in Walthamstow Pty Ltd v Caratti.

The decision to consolidate cases or hear them together depends on the circumstances of each case. It’s influenced by several key considerations, as described in cases such as Lois Nominees Pty Ltd v QBE Insurance (Australia) Ltd and A Goninan & Co Ltd v Atlas Steels (Aust) Pty Ltd.

The primary factor is whether consolidation would promote convenience, avoid multiple actions, and save time and expense.

Other considerations include the presence of common questions of law or fact, potential prejudice or unfairness to any of the parties, and if consolidation would facilitate a just resolution of the issues. Practical matters that may make consolidation inexpedient are also considered.

The court also highlighted the importance of promoting a just determination of litigation, efficiently disposing of the court's business, and making effective use of judicial and administrative resources, as outlined in Order 1 r 4B RSC, referencing Sino Iron Pty Ltd v Mineralogy Pty Ltd.

In Newbey, the court found common parties and similar transactions in both actions. There were likely overlapping issues of fact and law across both actions, based on the summary of the pleaded cases. However, the court concluded that consolidation could potentially be unfair to the defendants. Therefore, it decided to hear the cases together but not formally consolidate them.

Here are some of the key factors that courts often consider when deciding whether to consolidate cases, citing specific cases and paragraph numbers:

  1. Promotion of Convenience and Efficiency: The court assesses whether consolidation would promote convenience, save time, and avoid multiple actions. This principle is derived from the cases Lois Nominees Pty Ltd v QBE Insurance (Australia) Ltd [1995] 2 VR 513, 518 (Ormiston J) and A Goninan & Co Ltd v Atlas Steels (Aust) Pty Ltd [2002] NSWSC 585, [12] (Palmer J).

  2. Common Questions of Law or Fact: The presence of common questions of law or fact in the actions under consideration is a strong argument for consolidation. This was discussed in A Goninan & Co Ltd v Atlas Steels (Aust) Pty Ltd [2002] NSWSC 585, [12] (Palmer J).

  3. Potential Prejudice or Unfairness: The court weighs whether consolidation would create potential prejudice or unfairness to any of the parties involved. This factor is referenced in A Goninan & Co Ltd v Atlas Steels (Aust) Pty Ltd [2002] NSWSC 585, [12] (Palmer J).

  4. Just Resolution of Issues: The court considers whether consolidation would facilitate a just resolution of the issues at hand. This is referenced in Walthamstow Pty Ltd v Caratti [2018] WASC 321, [10] (Lundberg J).

  5. Practical Impediments to Consolidation: The court assesses any practical matters that may make consolidation inexpedient. This is derived from the case A Goninan & Co Ltd v Atlas Steels (Aust) Pty Ltd [2002] NSWSC 585, [12] (Palmer J).

  6. Effective Use of Judicial and Administrative Resources: The court also evaluates whether consolidation would enable more efficient use of judicial and administrative resources, as outlined in Order 1 r 4B RSC, referencing Sino Iron Pty Ltd v Mineralogy Pty Ltd [2018] WASC 51, [8] (Mitchell J).

  7. Fair and Efficient Administration of Justice: The overarching goal is to promote a just determination of litigation and efficiently dispose of the court's business, as highlighted in Sino Iron Pty Ltd v Mineralogy Pty Ltd [2018] WASC 51, [8] (Mitchell J).

These factors are not exhaustive, and the court's decision ultimately depends on the specific circumstances of each case.
