Mendonca v Chan and Naylor (Parramatta) Pty Ltd

The applicant, Mr. Mendonca, brought proceedings against his former employer, Chan and Naylor (Parramatta) Pty Ltd, alleging unlawful adverse action under the *Fair Work Act 2009* (Cth). Mr. Mendonca claimed that his dismissal was motivated by his engagement in a protected workplace right, specifically his participation in a protected industrial activity. The respondent employer contended that the dismissal was for a valid reason, namely serious and wilful misconduct. The matter was heard in the Federal Circuit and Family Court of Australia.

The central legal issue before the Court was whether the employer's stated reason for dismissal, serious and wilful misconduct, constituted a genuine reason for adverse action, or whether the dismissal was in fact taken because Mr. Mendonca had engaged in a protected workplace right. This required the Court to consider the definition of "misconduct," "serious misconduct," and "serious and wilful misconduct" in the context of employment law and to assess whether Mr. Mendonca's conduct met these thresholds.

Judge Cameron found that the employer had failed to establish that Mr. Mendonca's conduct amounted to serious and wilful misconduct. The Court reasoned that while Mr. Mendonca's actions may have constituted misconduct, they did not rise to the level of "serious and wilful" as contemplated by the employer's disciplinary policy and employment law principles. The Court concluded that the employer's stated reason for dismissal was not a genuine reason and that the adverse action was taken because of Mr. Mendonca's protected workplace right. The Court ordered that the respondent pay the applicant's costs.
