Legal Definitions - ex causa

Ex causa is a Latin phrase that translates to "by reason of" or "by virtue of a title." In legal contexts, it refers to the specific legal basis, justification, or authority that underpins a right, claim, or action. It explains why a particular legal status or action is valid and legitimate.

Here are some examples to illustrate this concept:

• Imagine a situation where a person inherits a valuable antique collection from a deceased relative. Their right to possess and own these items is established ex causa of the relative's last will and testament. The will serves as the legal "title" or "reason" that grants them ownership, distinguishing their claim from someone who might simply take the items without legal justification.

• Consider a real estate transaction where a developer purchases a plot of land to build new homes. The developer's right to take possession of the land and begin construction arises ex causa of the signed purchase agreement and the deed transferring ownership. These legal documents provide the essential "title" or "reason" for their legal claim to the property and their authority to develop it.

• Think about a government agency that issues a permit for a new business to operate. The agency's power to grant or deny such permits is exercised ex causa of the specific statutes and regulations enacted by the legislature. These laws provide the legal "title" or "reason" that authorizes the agency to regulate businesses and issue official permissions.
