Congress enacted Republic Act No. 9876, authorizing the Secretary of Energy to "fix and adjust the prices of petroleum products as the public interest may require." Petrowatch, an advocacy group, challenged the law as an unconstitutional delegation of legislative power to the executive, arguing that Congress abdicated its lawmaking function by granting the Secretary unfettered discretion to set prices. The Office of the Solicitor General countered that the standard "as the public interest may require" is sufficient to guide the Secretary's action and that the law is a valid exercise of the legislative power to delegate.
