Unlawful Activities (Prevention) Act (UAPA) is a stringent anti-terror law in India enacted to prevent activities that threaten the sovereignty, integrity, and security of the country. It allows the state to classify certain individuals and organisations as 'terrorist' and provides mechanisms for preventive detention, surveillance, and prosecution of such entities.

Under UAPA, the state has extensive powers, including:

• Designation of individuals and organisations as terrorist without requiring a conviction.
• Preventive detention and prolonged incarceration before trial.
• Wide interpretation of terrorist acts under Section 15, which can include disruption of public services or planning protests if deemed threatening.

The Supreme Court applied the principle of 'hierarchy of participation' under UAPA to distinguish the accused based on their alleged level of involvement in the Delhi riots. Khalid and Imam were considered central figures, allegedly involved in planning and coordinating the events, whereas the other five appellants were perceived to have lesser roles.

The Court emphasised Section 43D(5), which mandates assessing whether accusations are prima facie true rather than proving guilt. As a result, the Court held that Khalid’s and Imam’s bail applications could be denied despite prolonged incarceration. This decision reflects the balance UAPA attempts to maintain between protecting civil liberties and ensuring national security, but it also highlights how preventive detention can disproportionately affect individuals in politically sensitive cases.

The Supreme Court interpreted 'terrorist acts' under Section 15 of UAPA to include not only overt violence but also actions that could disrupt public services or instill fear. While legally defensible, this broad interpretation has potential chilling effects on civil liberties.

Critically, such expansive definitions may enable the state to apply UAPA to political dissent or protest movements, normalising prolonged incarceration even before a trial. For example, ordinary planning of protests on messaging apps like WhatsApp could be construed as evidence of a terroristic design. While the intent is to prevent violence, this approach risks conflating activism with terrorism, potentially undermining democratic rights such as the freedom of speech and assembly.

Thus, while the Court’s interpretation aligns with the letter of the law, it raises concerns about proportionality, fairness, and safeguarding fundamental rights.

Several factors contribute to prolonged trials under UAPA, especially in complex cases like the Delhi riots:

• Volume of evidence: In the Delhi riots case, there are reportedly around 700 witnesses and extensive documentation, making pre-trial procedures cumbersome.
• Complex legal provisions: UAPA allows preventive detention and prima facie assessments, requiring meticulous judicial review at multiple stages.
• Political sensitivity: Cases involving protest leaders or political dissenters often invite additional scrutiny, procedural delays, and litigation, as the state must carefully justify charges of terrorism.

Section 43D(5) of UAPA requires courts to determine whether the accusations against the accused are prima facie true before considering bail applications. This standard differs from the typical requirement to assess the full merits of a case.

In practice, this means:

• The court does not weigh the entire evidence but considers whether the allegations, if assumed true, justify continued detention.
• Bail is often denied in serious cases even if the accused maintains innocence, as seen with Khalid and Imam.

UAPA has frequently been invoked in politically sensitive cases in India, often targeting dissent or protest rather than conventional terrorism. Examples include:

• Delhi riots 2020: Umar Khalid and Sharjeel Imam were charged under UAPA for alleged roles in organizing protests, despite no overt act of violence directly attributed to them.
• Environmental and student activism: In some instances, activists advocating for environmental or social causes have faced UAPA charges when protests were construed as threats to public order.

• Prolonged pre-trial detention can disrupt education, careers, and personal life.
• The broad interpretation of 'terrorist acts' may discourage legitimate protest, undermining democratic participation.

The Delhi riots case illustrates several key lessons for judicial handling of UAPA cases:

• Proportionality in bail decisions: The Supreme Court granted bail to some accused based on a hierarchy of participation, indicating the need to differentiate levels of involvement rather than applying a blanket approach.
• Evidence management: With hundreds of witnesses and voluminous documents, rationalising the trial process is crucial to ensure timely justice.
• Balancing security and liberty: Preventive detention must be weighed against potential harm caused by prolonged incarceration, particularly for young individuals.
