Competition Commission v ATAL Building Services Engineering Limited [2025] HKCA 1120

In competition enforcement proceedings, correspondence and communications underlying a respondent's cooperation/leniency agreement with the Competition Commission are disclosable to non-settling respondents on fairness grounds (the 'warts and all' principle for accomplice evidence) and are not protected by without prejudice privilege once a settlement is successfully concluded, though the Tribunal may impose confidentiality safeguards.
