Topic: Retroactivity of Laws (Civil Code, Art. 4), Vested Rights Principle

A government recently enacted a new law that imposes stricter regulations on the use of fireworks. The law prohibits the use of certain types of fireworks and imposes heavy fines for violations. The law also provides that it shall take effect thirty (30) days after its publication in a national newspaper.

In the midst of the festive season, a group of individuals organized a fireworks display to celebrate a local event. They obtained the necessary permits and complied with all existing laws and regulations. However, the event was scheduled to take place two days after the new law was published.

One day before the scheduled event, the organizers were informed about the new law and its effectivity date. Concerned about potential legal consequences, they seek legal advice on the applicability of the new law to their planned fireworks display.

Based on the given scenario and the principle of retroactivity of laws and the vested rights principle, answer the following questions:

1. Is the new law on fireworks applicable to the planned fireworks display?
2. Can the organizers be held liable for violating the new law despite obtaining permits and complying with existing laws and regulations at the time of planning the event?
