A more thorough explanation:

Definition: Ex assensu suo is a Latin term that means "with his assent." It is used in a legal context, specifically in a default judgment for damages.

Example: If a defendant fails to respond to a lawsuit, the court may enter a default judgment against them. In such a case, the court may order the defendant to pay damages to the plaintiff "ex assensu suo," meaning that the damages are awarded with the defendant's assent, even though they did not actively participate in the legal proceedings.

Explanation: The use of "ex assensu suo" in a default judgment for damages indicates that the defendant is considered to have agreed to the damages awarded, even though they did not contest the lawsuit. This is because the defendant's failure to respond to the lawsuit is seen as an implicit agreement to the plaintiff's claims. The use of Latin terminology in legal contexts is common, and "ex assensu suo" is one example of a phrase that is still used today.
