a) Demetrio knew that a piece of land bordering the beach belonged to Ernesto. However, since the latter was studying in Europe and no one was taking care of the land, Demetrio occupied the same and constructed thereon nlpa sheds with tables and benches which he rented out to people who want to have a picnic by the beach. When Ernesto returned, he demanded the return of the land. Pemetrio agreed to do so after he has removed the nipa sheds. Ernesto refused to let Demetrio remove the nlpa sheds on the ground that these already belonged to him by right of accession. Who is correct? (3%)
