Ms Hu's case centred on whether Passion Fresh could be joined as a controlling third party to her personal grievance against Whver. The Employment Relations Act 2000 allows employees to join controlling third parties if they have raised a grievance with their employer and notified the third party.
The Court found that Ms Hu had not raised her grievance with Whver, her actual employer. Instead, she had communicated her concerns directly to Passion Fresh. This procedural misstep meant Passion Fresh could not be joined as a controlling third party, and the Court dismissed her challenge.
