IT Act 2000
Section 39
Notice of Suspension or Revocation of Digital Signature Certificate
THE STATUTE
Original Text
Where a Digital Signature Certificate has been suspended or revoked under section 37 or section 38, the Certifying Authority shall communicate the same to the subscriber, and shall also publish a notice of such suspension or revocation, as the case may be, in the repository specified in the Digital Signature Certificate for publication of such notice.
Simplified
Section 39 is the publication obligation that closes the PKI notification loop: once a Digital Signature Certificate is suspended (Section 37) or revoked (Section 38), the Certifying Authority has two mandatory duties. First, it must communicate the suspension or revocation directly to the subscriber — this is a personal notification obligation. Second, it must publish a notice of the suspension or revocation in the repository specified in the certificate itself. In the PKI architecture, every Digital Signature Certificate contains a field pointing to the CA's repository — typically a Certificate Revocation List (CRL) distribution point and/or an Online Certificate Status Protocol (OCSP) responder URL. When a certificate is suspended or revoked, the CA must update these repositories so that any software or system checking the certificate's validity will discover the changed status. The practical significance is profound: a relying party who checks a certificate's status after the Section 39 notice has been published and still relies on the certificate does so at their own risk. Conversely, a relying party who relied on a certificate before a suspension or revocation was published in the repository may have a defence that they acted in good faith on a then-valid certificate. Section 39 therefore fixes the legal moment at which the world is deemed to have notice of a certificate's invalid status — the moment of publication in the repository, not the moment of internal CA decision.
Legal Evolution
Section 39 was in the original IT Act 2000. The provision is the Indian implementation of the CRL (Certificate Revocation List) concept that was central to the X.509 PKI standard and the ABA Digital Signature Guidelines. CCA regulations have since updated CRL update frequency requirements for licensed CAs.
Key Amendments
Unchanged since the original IT Act 2000.
CCA-licensed CAs are required under regulations to update CRLs within specified timeframes after suspension or revocation.
