Question

I. EFFECT AND APPLICATION OF LAWS
B. Ignorance of the Law, (Civil Code, Art. 3) Ignorance of Fact

Scenario:

Marie, a law-abiding citizen, recently purchased a piece of property. She was unaware that there was an existing easement on the property, which restricts her from blocking the access road connecting her property to the main road. Marie proceeded to build a fence that blocked the access road, causing inconvenience to her neighbors.

Ellen, one of Marie's neighbors, filed a complaint against her for violating the easement. During the court proceedings, Marie claims that she was ignorant of the existence of the easement and therefore should not be held liable for her actions.

Discuss whether Marie's claim of ignorance of fact can be considered as a valid defense in this case. Support your answer with relevant provisions of the Civil Code.
