A more thorough explanation:

Sui juris is a Latin term that means "of one's own right; independent." It has three meanings:

1. Being of full age and capacity.
2. Possessing full social and civil rights.
3. In Roman law, it refers to anyone who is not under the control of another person and is capable of owning property and enjoying private-law rights.

It is important to note that this status is not relevant to public law.

Example 1: John is 25 years old and has the legal capacity to enter into contracts and make decisions on his own.

Example 2: Mary is a citizen of the United States and has the right to vote, own property, and enjoy other civil rights.

Example 3: In ancient Rome, a person who was not under the control of another, such as a child or a slave, was considered sui juris and had the right to own property and make legal decisions.

These examples illustrate the different meanings of sui juris. In example 1, John is of full age and capacity, meaning he is legally able to make decisions on his own. In example 2, Mary possesses full social and civil rights, which means she has the same rights as any other citizen. In example 3, the concept of sui juris in Roman law refers to a person who is not under the control of another and has the right to own property and make legal decisions.
