The provided legal document primarily discusses the constitutional validity of provisions under the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989, and related procedural aspects, especially regarding anticipatory bail and the specific provisions of the Act. It does not directly address the accountability of a public servant to register a First Information Report (FIR).

However, based on general legal principles and constitutional mandates, a public servant, especially those in law enforcement, has a constitutional and legal obligation to register an FIR when a cognizable offence is reported to them. Under the constitutional framework, particularly Articles 14 and 21, every individual has the right to equality before the law and the right to life and personal liberty, which includes the right to seek legal remedy and justice. The obligation to register an FIR is also reinforced by statutory provisions and directives that mandate police authorities to register FIRs upon receiving information about cognizable offences.

Failure of a public servant or police officer to register an FIR when a cognizable offence is reported can be challenged as a violation of constitutional rights and statutory duties. Such inaction can be subject to judicial review and appropriate legal remedies, including directions from courts to the authorities to perform their statutory functions.

In summary, a public servant, especially in law enforcement, is accountable under the law to register an FIR when presented with credible information regarding a cognizable offence, ensuring the protection of victims' rights and the enforcement of the rule of law.
