From PTA to PSTA: Why Sri Lanka Needs National Security Without Returning to Political Repression
The NPP Government's proposed Protection of the State from Terrorism Bill seeks to replace a controversial 1979 law with a new counterterrorism framework. But can Sri Lanka protect its citizens, international security interests and democratic freedoms at the same time?
By ColomboWire – Special Political Analysis
For more than four decades, Sri Lanka's Prevention of Terrorism Act (PTA) has remained one of the most controversial pieces of legislation in the country's legal system. Introduced in 1979 as temporary legislation, it became a permanent feature of the country's national security framework and attracted sustained criticism over arbitrary arrests, prolonged detention and the potential misuse of state power against political opponents, journalists and civil society activists.
The National People's Power (NPP) Government came to office promising to abolish oppressive legislation, including the PTA. It was a commitment made in the interests of democracy, civil liberties and the restoration of public confidence in the rule of law.
However, abolishing an existing counterterrorism law does not mean abolishing the responsibility of the State to protect its citizens.
This is the central argument behind the Government's proposed Protection of the State from Terrorism Bill (PSTA).
The Government's position is that Sri Lanka cannot leave a legislative vacuum in an increasingly interconnected world, where international terrorist networks, extremist organisations, recruitment operations, financial networks and technology-enabled threats can cross national borders.
The challenge is to establish a legal framework that protects national security without giving the executive branch unrestricted authority over the lives and freedoms of citizens.
Abolishing the PTA does not mean abandoning national security
There is an important distinction between opposing the misuse of counterterrorism legislation and opposing the existence of counterterrorism legislation altogether.
Sri Lanka has experienced the devastating consequences of terrorism. The country has a responsibility to ensure that its territory is not used as a centre for international terrorist recruitment, financing, planning or operations.
Modern security threats are not necessarily confined to conventional armed organisations. They can involve international financial transfers, online recruitment, cyber-enabled attacks, extremist propaganda, cross-border networks and the coordination of violent activities.
A responsible government cannot simply announce that it has abolished the PTA and then leave the country without an effective legal mechanism to investigate and prosecute genuine terrorist offences.
The NPP Government's argument is that a replacement must be capable of addressing these threats while correcting the serious deficiencies associated with the old legislation.
That is the policy challenge behind the PSTA.
Why introduce a replacement after coming to power?
The NPP's election manifesto promised the abolition of the PTA. However, the Government also has constitutional responsibilities to maintain public order, protect national security and safeguard the lives of citizens.
The proposed PSTA emerged following the appointment of a technical expert committee and the preparation of a new legislative framework. Cabinet approved the proposal in August 2026, and the Bill was gazetted in September before being presented to Parliament on 6 October 2026.
Importantly, the proposed legislation expressly provides for the repeal of the Prevention of Terrorism (Temporary Provisions) Act No. 48 of 1979.
This is not simply a change of name. The Government says it is seeking to establish a different legal framework for identifying, investigating, prosecuting and punishing terrorism-related offences.
The proposed legislation also addresses activities connected with terrorism committed outside Sri Lanka and the use of Sri Lankan territory for preparing terrorist activities overseas.
For a country strategically positioned in the Indian Ocean, these international dimensions of national security cannot be ignored.
Judicial oversight must be the foundation
One of the most important questions surrounding the new legislation is whether the judiciary will have sufficient authority to prevent arbitrary detention and the abuse of investigative powers.
The proposed Bill contains provisions concerning judicial production of suspects, access to lawyers, magistrates' inspections of approved detention facilities, Human Rights Commission notification and visits, and judicial approval for detention beyond specified periods.
It also provides for maximum detention periods and procedures governing the treatment of suspects.
These provisions are significant because the history of the PTA demonstrates why national security legislation must never become a substitute for judicial process.
The police and security agencies must be able to investigate genuine terrorist offences. But the courts must remain capable of examining the legality of arrests, detention and prosecution.
The Government's case for the PSTA will ultimately depend not simply on the safeguards written into the legislation, but on whether those safeguards operate effectively in practice.
A modern threat requires a modern legal response
Sri Lanka is part of an international security environment in which terrorism is not restricted to one geographical location. Terrorist organisations can operate through international connections, recruit individuals online, raise funds across borders and exploit weaknesses in financial and communications systems.
The Easter Sunday attacks demonstrated the devastating consequences of intelligence failures and inadequate coordination between security institutions.
The lesson is not that every citizen should be treated as a security suspect. It is that the State must have the capacity to identify credible threats, investigate them lawfully and prevent attacks before innocent lives are lost.
Cybersecurity is another important consideration. Cyberattacks against government infrastructure, financial institutions and essential services can create serious national security risks. However, cybercrime and cybersecurity must also be addressed through appropriately tailored legislation. A counterterrorism law should not become a general-purpose instrument for regulating online criticism or political expression.
The Government therefore needs a coherent framework in which national security agencies, the police, intelligence services and judicial institutions can cooperate without compromising constitutional freedoms.
The Government must answer its critics
The introduction of the PSTA has generated criticism from human rights organisations, civil society groups and political activists.
Human Rights Watch, Amnesty International and the World Organisation Against Torture have raised concerns about the breadth of the terrorism definition, detention powers and the potential impact on freedom of expression, assembly and association.
These criticisms cannot simply be dismissed as opposition to national security.
The proposed legislation retains certain executive powers, including detention and organisational proscription powers, which require particularly rigorous scrutiny. Judicial oversight exists in several areas, but critics argue that it is not sufficiently comprehensive.
The Government must therefore demonstrate, provision by provision, how the new framework differs from the PTA and how it prevents the abuses associated with the old law.
There is also an important factual issue that deserves transparency: the PTA remained in force while the replacement Bill was being developed, and it was used in 2026. The Government cannot establish its human rights credentials merely by promising that the new legislation will be different. Its record of implementation must support that promise.
International confidence and Sri Lanka's strategic interests
There is also an economic and diplomatic dimension to this legislation.
International investors, financial institutions and Sri Lanka's regional security partners require confidence that the country has an effective legal framework to address terrorism, organised violence and cross-border security threats.
Counterterrorism cooperation, intelligence-sharing arrangements and bilateral security agreements depend on functioning legal institutions and clearly defined responsibilities.
Sri Lanka's relationship with India, China, the United Kingdom, the United States and other international partners includes important discussions concerning maritime security, financial crime, intelligence cooperation and regional stability.
A credible domestic legal framework can support those relationships.
There is also a direct economic consideration. Sri Lanka's continued access to the European Union's GSP+ trade concessions is linked to its implementation of international human rights and governance commitments. Replacing the PTA with legislation that genuinely respects those obligations is therefore important to the country's exporters, manufacturers and workers.
However, international confidence cannot be secured through tougher legislation alone. It requires credible judicial independence, accountability and respect for fundamental rights.
National security and democratic freedom must coexist
The NPP Government faces a difficult responsibility.
On one side, it must ensure that Sri Lanka never becomes a safe operating environment for international terrorist organisations. On the other, it must ensure that counterterrorism powers cannot be used to intimidate political opponents, suppress peaceful demonstrations or silence journalists.
The distinction between a terrorist organisation and a legitimate political movement must remain absolutely clear.
Peaceful political activism, trade union activity, journalism, academic research, religious expression and public criticism of the Government must not be treated as terrorism simply because they challenge those in power.
The judiciary must have the authority to intervene effectively whenever investigative or executive powers are abused.
Parliament must scrutinise the Bill carefully, and the Government should take seriously the recommendations of independent legal experts, the Human Rights Commission and civil society.
These are not obstacles to national security. They are essential conditions for legitimate national security.
The real test of the NPP Government
The PSTA should ultimately be judged on three fundamental questions.
First, can it protect Sri Lankan citizens against genuine terrorist threats and international extremist networks?
Second, can it prevent the arbitrary detention and political misuse that damaged public confidence in the PTA?
Third, can it establish a legal framework that satisfies Sri Lanka's constitutional obligations and international human rights commitments?
These questions deserve serious parliamentary and public debate.
The NPP Government came to power promising a different political culture, greater accountability and respect for the rule of law. Its approach to counterterrorism legislation will be one of the important tests of those commitments.
A government cannot protect democracy by abandoning national security. Equally, it cannot protect national security by sacrificing democracy.
Sri Lanka needs a legal framework that is strong against terrorism but restrained against the misuse of state power.
The abolition of the PTA and its replacement with the PSTA should therefore represent an opportunity to establish a new balance between security, justice and individual liberty.
The ultimate measure of success will not be the number of powers granted to the security services or the number of people detained. It will be whether genuine terrorist threats can be prevented and prosecuted while the ordinary Sri Lankan citizen remains protected by the Constitution and the independence of the judiciary.
That is the standard against which the NPP Government should be judged.
