A power is what an institution is allowed to do. A function is the purpose that power serves. Keeping them apart stops your answers from repeating the same point in two words.
This lesson builds on explaining the roles of major institutions and belongs to the wider chapter on constitutional monarchy and parliamentary democracy.
How do you tell them apart?
Use two questions. “What can it do?” points to a power. “Why does it do it?” points to a function.
| Institution | Power (what it can do) | Function (why) |
|---|---|---|
| Parliament (Dewan Rakyat and Dewan Negara) | Passes federal laws | Makes sure laws come from elected representatives |
| Cabinet | Decides government policy | Runs the country day to day under parliamentary scrutiny |
| Judiciary | Decides court cases | Settles disputes by applying the law independently |
Notice that each function can be stated only after the power is clear. The function is the reason the power exists.
Worked example from a source
Here is a real statement about Malaysia. Under Part IX of the Federal Constitution, the courts (the Federal Court, the Court of Appeal and the High Courts) decide cases, and the Constitution is the supreme law. 1
The question asks: “Explain the power and the function of the institution in the statement.”
Identify the institution first: the judiciary. The power shown is deciding court cases. The function is to make sure everyone, including the government, follows the law, since the Constitution is the supreme law.
A full answer: “The judiciary has the power to decide cases through the Federal Court, the Court of Appeal and the High Courts. Its function is to ensure the law is applied to all, so that the government cannot act beyond what the Constitution allows.”
The mistake to avoid
A frequent slip is to write the same idea twice and call it a power and a function.
| Weak answer | Why it fails |
|---|---|
| “Power: makes laws. Function: makes laws for the country.” | The second sentence repeats the first |
| “Power: decides cases. Function: settles disputes by applying the law independently.” | Correct: the function gives a separate purpose |
The fix is to ask whether your function sentence contains a new idea. If it only rewords the power, rewrite it with a reason.
Check yourself
Give one power and one function of Parliament.
Answer
Power: Parliament can pass federal laws. Function: it makes sure the rules governing the country come from the people’s elected representatives.
The power names an action. The function explains why that action matters.
