Question

In a legal dispute between two parties, Judge Hernandez presided over the case and listened to the arguments presented by both sides. The trial lasted for several months, with extensive evidence and testimonies presented. After careful consideration, Judge Hernandez concluded the trial and closed the case. However, he failed to render a written decision within the mandated period.

What is the duty of Judge Hernandez under Article 9 of the Civil Code? Discuss the effect and application of this provision in relation to the duty to render judgment.
