Question

Angelo is a law student who is studying for his bar exams. One of the topics he is reviewing is the repeal of laws, specifically Article 7 of the Civil Code. As he delves deeper into the subject, he encounters several scenarios and questions regarding the effect and application of repealed laws. Answer the following questions based on the given scenarios:

1. Scenario 1:
   The Philippine Congress passed a new law that explicitly repeals a specific provision of an existing law. The repealed provision is related to the rights of tenants in commercial buildings. A tenant, who signed a lease contract prior to the new law's enactment, claims that his rights under the previous law should still be upheld. Is the tenant correct? Discuss the legal effect of the repeal of laws in this scenario.
2. Scenario 2:
   A local government unit passes an ordinance prohibiting the use of single-use plastics within its jurisdiction. Subsequently, the national government enacts a law that repeals all ordinances banning the use of single-use plastics. Can the local government unit still enforce its ordinance despite the repeal? Explain the application of repealed laws in this situation.
3. Scenario 3:
   The President issued an executive order that repeals a previous executive order mandating certain qualifications for government positions. Despite the repeal, a government agency continues to implement the qualifications requirement as stated in the previous executive order. Assess the validity of the agency's actions in light of the repeal of laws.
