Which of the following is not a principle of the constitution is separation of powers, popular, secondary tranquility, or checks and balances

Popular is not a principle of the Constitution. The correct answer is "Popular".

The principle that is not a principle of the constitution is "secondary tranquility."

To determine which of the options is not a principle of the Constitution, we need to assess each option and identify the correct answer. Let's go through each option:

1. Separation of powers: This is a fundamental principle of the Constitution, which aims to distribute governmental powers among three branches—legislative, executive, and judicial—so that no single branch becomes too powerful. This principle acts as a system of checks and balances.

2. Popular: It seems like a word is missing in the option you provided. If you meant "popular sovereignty," then it refers to the idea that the source of governmental power lies with the people. Popular sovereignty is a principle that emphasizes the authority of the people in a democratic society and is indeed part of the Constitution.

3. Secondary tranquility: This phrase does not relate to any constitutional principle. It seems like there might be an error or some confusion regarding this term. It does not represent one of the principles of the Constitution.

4. Checks and balances: This principle, closely related to the concept of the separation of powers, ensures that no single branch of government becomes too powerful. It establishes a system in which each branch of government has the ability to limit or check the powers of the other branches.

From the options provided, "secondary tranquility" is not a principle of the Constitution. It is important to note that the primary term used in constitutional discussions is "domestic tranquility," which refers to the maintenance of peace and order within a country.

In conclusion, the correct answer is "secondary tranquility" as it is not a principle of the Constitution.
