Here’s what an executive-led government really means in Hong Kong
The legislature and judiciary have a constitutional duty to rally behind the executive while exercising their powers independently
In my experience, most people misunderstand the concept of “separation of powers”, and so I would not be at all surprised if most people also misunderstand the term “executive-led government”. In the case of separation of powers, the confusion usually arises from the use of the word “separation”. It connotes a meaning of absolute independence or alienation. A better word would have been “division”.
In a way, they are two sides of the same coin. The difference between various systems of government usually relates to the degree of the division of power and how those powers are exercised, rather than the constitutional order of that system of government.
Take the United Kingdom’s system of government as an example. It is what is called a parliamentary system, under which parliament is supreme. The majority party in parliament gets to form the government. This government is answerable to parliament to the extent that parliament can bring down a government; but once it is formed, the executive government has the power to introduce laws, parliament gets to pass them and the courts get to interpret and apply them, with the government then executing or enforcing them.
