Outcomes
Appeal allowed.
The Employment Tribunal erred in its assessment of cause of action estoppel, Rule 52, and Henderson v Henderson principles. It failed to properly identify the complaints in the 2017 and 2021 claims, leading to perverse conclusions.
Matter remitted to a different Employment Tribunal.
The errors made by the Employment Tribunal were fundamental, requiring a redetermination of whether the 2021 claim was precluded by the 2017 claim.
