Question

Juan and Maria recently entered into a lease agreement for a commercial property. The lease agreement states that the monthly rent is Php 50,000, payable on the 1st day of every month. However, a dispute arises between Juan and Maria regarding the interpretation of the word "month" in the lease agreement. Juan insists that it refers to a 30-day period, while Maria argues that it should be interpreted as a calendar month.

With this dilemma in mind, discuss the following:

1. Explain the principle of interpretation of doubtful statutes as provided in Article 10 of the Civil Code.
2. Examine the possible courses of action that Juan and Maria can take to resolve their dispute, considering the principle of interpretation of doubtful statutes.
