I. Introduction

This memorandum provides an exhaustive comparative analysis of Republic Act No. 9372, known as the Human Security Act of 2007 (HSA), and Republic Act No. 11479, known as the Anti-Terrorism Act of 2020 (ATA). The objective is to delineate the key provisions, jurisprudential foundations, and practical implications of both statutes within the realm of Philippine criminal law. The ATA, which repealed the HSA, represents a significant legislative shift in the legal framework for defining, preventing, and prosecuting acts of terrorism. This analysis will cover the constitutional and statutory context, definitions of central crimes, procedural mechanisms, penalties, and the salient legal controversies surrounding each law.

II. Statutory and Constitutional Context

Both laws were enacted pursuant to the state’s police power and its duty to protect life, liberty, and property from serious threats. The HSA was framed as a measure to secure the state and protect people from terrorism, explicitly stating that it was not a law against dissent. The ATA builds upon this premise but operates within a more expansive and proactive framework. The constitutional anchors for both include the Bill of Rights, particularly provisions on due process, equal protection, the right against unreasonable searches and seizures, the right to counsel, the right to a speedy trial, and the presumption of innocence. A primary legal distinction lies in their treatment of these rights, with critics arguing the ATA creates more significant tensions with constitutional safeguards than its predecessor.

III. Definition of Terrorism

The definition of the crime of terrorism is the cornerstone of each law and marks a critical point of divergence.

Under the HSA, terrorism was defined as the commission of any of the predicate crimes under the Revised Penal Code (e.g., murder, kidnapping, arson) and specified laws, “thereby sowing and creating a condition of widespread and extraordinary fear and panic among the populace, in order to coerce the government to give in to an unlawful demand.” This definition required a direct causal link between a serious predicate crime and the specific intent to coerce the government.

The ATA provides a broader definition. It defines terrorism as engaging in acts intended to cause death or serious bodily injury, endanger a person’s life, or cause extensive damage to property, with the purpose of: (1) intimidating the general public or a segment thereof; (2) creating an atmosphere of fear; or (3) influencing, intimidating, or coercing the government to do or abstain from doing an act. Crucially, the ATA removes the requirement of a predicate crime and expands the purpose beyond coercing the government to include intimidating the public.

IV. The Crime of Conspiracy to Commit Terrorism

Both laws penalize conspiracy, but with different thresholds.

The HSA punished proposal to commit terrorism and conspiracy to commit terrorism only when the proposal or conspiracy was “for the purpose of terrorism” and had “actually resulted in the commission of a terrorism act.” This was a high bar requiring an overt act and a completed act of terrorism.

The ATA significantly lowers this threshold. It penalizes conspiracy to commit terrorism when “two or more persons come to an agreement concerning the commission of the crime of terrorism and decide to commit it.” No overt act is required under the ATA’s text, making mere agreement punishable as a separate felony.

V. Designation and Proscription of Terrorist Individuals and Groups

This is a new and potent mechanism introduced by the ATA, with no direct counterpart in the HSA.

The HSA had no formal administrative designation process. The ATA establishes a legal procedure for the Anti-Terrorism Council (ATC) to “designate” individuals, groups, organizations, or associations as terrorist. This designation, based on “probable cause” and for the purpose of freezing assets under the Anti-Money Laundering Act, can occur even without a judicial hearing. Furthermore, the Department of Justice can initiate a judicial proscription process before the Court of Appeals to declare a group a terrorist organization, which carries legal consequences for membership and support.

VI. Surveillance, Detention, and Arrest Procedures

The regimes for investigation and detention differ markedly in their perceived intrusiveness.

The HSA allowed for surveillance of suspects and interception of communications upon a written order from the Court of Appeals, granted only upon a finding of probable cause. Warrantless detention was limited to three days, after which the person must be charged in court or released.

The ATA extends the period of warrantless detention. Law enforcement agents can detain a suspected terrorist without a judicial warrant of arrest for up to 14 calendar days (extendable by 10 more days in certain circumstances). Surveillance and wiretapping orders from the Court of Appeals are valid for up to 90 days, renewable. The law also allows for the examination of bank accounts and financial records upon order of the Court of Appeals.

VIII. Penalties and Liabilities

The ATA imposes harsher penalties. While the HSA prescribed a penalty of 40 years of imprisonment without the benefit of parole, the ATA imposes life imprisonment without parole for the crime of terrorism. The ATA also introduces a graduated scheme of penalties for providing material support to terrorists, recruiting members for a terrorist organization, and inciting to commit terrorism through means “without taking direct part in the execution of the act.” Notably, the ATA removed the HSA’s provisions for officer liability (P500,000 daily fine for unlawful detention) and automatic damages (P500,000) for acquitted suspects, which were seen as deterrents against abuse.

IX. Salient Legal Issues and Constitutional Challenges

The HSA was criticized as ineffectual, leading to only one successful conviction. Its stringent safeguards (e.g., officer liability, damages for acquittal) were cited as reasons for law enforcement’s reluctance to use it.

The ATA has faced profound constitutional challenges. Petitions before the Supreme Court argued it is void for vagueness and overbreadth, particularly its definitions of terrorism and the crime of inciting to terrorism. Critics contend it infringes on freedom of speech, expression, and assembly. The provisions on warrantless detention, the ATC’s designation power without prior judicial hearing, and the criminalization of mere conspiracy are challenged as violations of due process, the right against unreasonable seizure, and the right to association. In a 2021 decision, the Supreme Court declared two parts of the ATA’s implementing rules unconstitutional but largely upheld the law itself, while providing a narrowed interpretation of terms like “incitement.”

X. Conclusion and Implications

The evolution from the HSA to the ATA represents a fundamental transformation in the Philippine legal approach to terrorism. The ATA adopts a more expansive definition of terrorism, lowers the threshold for preparatory crimes like conspiracy, grants extended detention powers to law enforcement, and creates an administrative designation process. While the government asserts these tools are necessary for preempting modern terrorist threats, the legal community and civil society remain vigilant about potential encroachments on civil liberties. The ATA’s ultimate impact on the balance between state security and individual rights will be determined by its implementation and continuing judicial scrutiny. The comparative table in Section VII succinctly captures the operational shift from the restrictive, post-crime HSA to the proactive, pre-crime oriented ATA.
