A more thorough explanation:

Definition: Extra jus means beyond the law or more than what the law requires. It is a Latin term.

Example: If a company decides to give its employees a bonus that is not required by law, it is considered extra jus.

This example illustrates that the company is going beyond what is legally required and providing additional benefits to its employees.

Extralateral right refers to the right of a mining company to extract minerals from a vein that extends beyond the boundaries of its property. This right is based on the Apex Rule, which allows a company to follow a vein of minerals even if it extends beyond its property line.

Extra legem means outside the law or beyond the protection of the law. It refers to actions or activities that are not covered by the law or that are not protected by legal rights.
