Question

A certain municipality has enacted an ordinance prohibiting the use of plastic bags in all commercial establishments within its jurisdiction. The ordinance imposes a fine and other penalties for non-compliance. Several business owners challenged the legality of the ordinance, arguing that it violates the Generality Principle of Penal Laws under Article 14 of the Civil Code. They claim that the ordinance unfairly discriminates against businesses and that it is not applicable to all municipalities in the country.

Identify the main principle under Article 14 of the Civil Code and explain its application to the given scenario. Discuss whether the ordinance violates this principle or not, providing legal basis to support your argument.
