Overview
Res judicata concerns the finality of litigation — the principle that a matter already decided by a competent court should not be litigated again between the same parties. The reported record in this area runs from cause-of-action estoppel, which bars a fresh claim on a cause already adjudicated, to issue estoppel, which prevents the re-argument of a particular issue necessarily decided before, to the extended doctrine that treats the raising of points that could and should have been advanced in earlier proceedings as an abuse of the court's process. The reported judgments turn on questions such as whether there was a final decision on the merits, whether the parties or their privies are the same, and how the doctrine interacts with settlements, consent orders, and foreign judgments.
The firms and counsel who appear most often in the reported res judicata record are drawn from the full-service commercial-disputes practices that carry the contract, insolvency, and property claims in which a plea of res judicata is commonly raised. Their prominence reflects the way the doctrine attaches to litigation across a range of subject matter rather than a specialisation in the doctrine alone. The tables identify the counsel and firms named in the reported judgments, a description of activity rather than an assessment of any matter's merits.
The court record also shows where these disputes are resolved. Res judicata is typically raised as a preliminary or defensive point within a larger dispute, and the more consequential arguments — over the scope of an earlier decision or the reach of the extended doctrine — cluster in the trial and appellate divisions where the finality of prior proceedings is tested. The tables below rank named firms and counsel purely by how often they appear in the reported res judicata record; the figures describe activity in reported litigation, not the quality of any representation or the outcome of any matter.
