A more thorough explanation:

Ejectment is a legal action that allows someone who has the right to possess a piece of real property, but is not currently in possession of it, to sue someone who is currently in possession of the property. The person bringing the lawsuit must prove that they have the right to exclusive possession of the property, which is known as "paramount title."

For example, let's say that John owns a piece of land, but he leases it to Jane for a period of ten years. After five years, Jane stops paying rent and refuses to leave the property. In this case, John could bring an action of ejectment against Jane to regain possession of the property.

Another example would be if someone were to squat on a piece of land that they do not own or have any legal right to possess. The true owner of the land could bring an action of ejectment against the squatter to regain possession of the property.

These examples illustrate how ejectment can be used to protect the rights of property owners and ensure that they are able to possess and use their property as they see fit.
