Case Summary (G.R. No. 47800)

Case Background

  • Petitioner: Maximo Calalang, a private citizen and taxpayer of Manila.
  • Respondents: A.D. Williams (Chairman of the National Traffic Commission), Vicente Fragante (Director of Public Works), Sergio Bayan (Acting Secretary of Public Works and Communications), Eulogio Rodriguez (Mayor of Manila), and Juan Dominguez (Acting Chief of Police of Manila).
  • Legal Action: Petition for a writ of prohibition against the enforcement of regulations prohibiting animal-drawn vehicles on specified streets in Manila.

Legal Framework

  • Commonwealth Act No. 548:
    • Authorizes the Director of Public Works, with the Secretary's approval, to promulgate traffic regulations for national roads.
    • Focuses on promoting safe transit and avoiding obstructions on designated national roads.

Petitioner's Argument

  • Unconstitutionality: Calalang claims that Commonwealth Act No. 548 constitutes an unlawful delegation of legislative power.
  • Interference with Business: The regulations infringe on personal liberty, freedom of locomotion, and legitimate business practices.
  • Social Justice Concerns: The petitioner argues that the regulations violate constitutional mandates regarding social justice and economic security.

Court’s Analysis

  • Delegation of Power:

    • The court held that the authority granted by Commonwealth Act No. 548 does not involve the delegation of legislative power, but rather the execution of existing law.
    • The act allows for administrative discretion based on factual circumstances regarding road conditions and public convenience.
  • Police Power:

    • The enforcement of the regulations falls within the state's police power aimed at public welfare and safety.
    • The court emphasized that the state may impose restrictions in the interest of public welfare, which may limit individual liberties for the collective good.
  • Social Justice:

    • The court clarified that social justice aims to balance individual rights with the greater good of society, ensuring the welfare of all citizens.
    • It underscored that social justice is not merely a sympathy towards specific groups but requires equitable treatment across society.

Important Provisions and Decisions

  • Regulatory Authority: The Director of Public Works, with the Secretary's approval, can enact regulations for traffic control, which are considered administrative functions, not legislative.
  • Duration of Regulations: The regulations in question were set to be enforced for a period of one year from the opening of the Colgante Bridge to traffic.
  • Enforcement: The Mayor and Chief of Police are responsible for enforcing the regulations against animal-drawn vehicles.

Ruling

  • The Supreme Court denied the writ of prohibition, indicating that the arguments presented by the petitioner were without merit and reaffirming the validity of the regulations in light of public safety and welfare.
