The implementation of the new Competition Ordinance (Chapter 619 of the Laws of Hong Kong) (the Competition Ordinance) on 14 December 2015 will mark the first time that Hong Kong has a general and cross-sector competition law.


The Competition Ordinance was enacted on 14 June 2012 as a general and cross-sector competition law to curb anti-competitive conduct, and will come into full effect on 14 December 2015.

Three major forms of anti-competitive conduct are prohibited under the First Conduct Rule, the Second Conduct Rule (collectively referred to as the Conduct Rules) and the Merger Rule. In this issue, we will discuss the Second Conduct Rule.

What is the Second Conduct Rule?

This rule applies to unilateral conduct by an undertaking, regardless of whether the undertaking itself is, or the abusive conduct takes place, inside or outside of Hong Kong. Abusive conduct which takes the form of an agreement may also contravene the First Conduct Rule.

A flowchart illustrating how the Second Conduct Rule works is set out in the Appendix.
