Appeals to the Cyber Appellate Tribunal lie against orders of the Controller or an adjudicating officer, except consent orders of an adjudicating officer. Appeals must be filed in the prescribed form with the prescribed fee within forty-five days of receipt, subject to admission of delayed filings for sufficient cause. After hearing the parties, the Tribunal may confirm, modify, or set aside the order.

The Central Government is to provide the Cyber Appellate Tribunal with officers and employees as it considers fit. Their functions are performed under the general superintendence of the Presiding Officer, and their salaries, allowances, and other conditions of service are prescribed by the Central Government.

Central Government orders appointing the Presiding Officer of a Cyber Appellate Tribunal are final and cannot be challenged in any manner. Acts and proceedings before the Tribunal remain insulated from challenge merely because of a defect in the Tribunal's constitution. The provision preserves the validity of proceedings notwithstanding such constitutive defects.

Resignation by the Presiding Officer of the Cyber Appellate Tribunal requires written notice to the Central Government, with continuation in office until earlier permitted relinquishment, successor appointment, expiry of three months, or expiry of the term, whichever occurs first. Removal is limited to proved misbehaviour or incapacity following an inquiry by a Judge of the Supreme Court, with notice of charges and a reasonable opportunity to be heard.

Vacancies in the office of the Presiding Officer of the Cyber Appellate Tribunal, other than those caused by temporary absence, must be filled by the Central Government through appointment of another person in accordance with the applicable provisions. Pending proceedings may continue from the stage reached when the vacancy is filled, preserving procedural continuity.

Salary, allowances, and other terms and conditions of service of the Presiding Officer, including pension, gratuity, and other retirement benefits, are to be determined by prescribed terms. Post-appointment protection prevents any variation that places the Presiding Officer at a disadvantage in relation to salary, allowances, or other conditions of service.

Presiding Officer of the Cyber Appellate Tribunal holds office for five years from entering office, subject to earlier cessation of tenure upon attaining sixty-five years. The office cannot continue beyond the specified retirement age even where the five-year period has not expired.

Appointment as Presiding Officer of the Cyber Appellate Tribunal requires eligibility as a High Court Judge, former High Court Judge, or person qualified to become a High Court Judge. Eligibility also extends to a current or former member of the Indian Legal Service who has held a Grade I post for at least three years. These are mandatory conditions for appointment.

Section 49 of the Information Technology Act, 2000 establishes the Cyber Appellate Tribunal as a single-member body, whose sole member is designated the Residing Officer. The Central Government appoints the Residing Officer by notification. The prescribed composition establishes a singular institutional structure and formal appointment mechanism, with no additional members included in the Tribunal's composition.

Section 48 mandates the Central Government, through notification, to establish one or more appellate tribunals known as the Cyber Regulations Appellate Tribunal. The establishing notification must also specify the matters and places in relation to which the Cyber Appellate Tribunal may exercise jurisdiction. The framework links the tribunal's creation and territorial and subject-matter jurisdiction to notification-based governmental specification.

Compensation quantum is adjudged by the adjudicating officer with due regard to quantifiable unfair gain or advantage resulting from the default, loss caused to any person by the default, and the repetitive nature of the default.

Qualified adjudicating officers may be appointed to inquire into contraventions of applicable statutory provisions, rules, regulations, directions and orders. The concerned person must receive a reasonable opportunity to make representations before a penalty or compensation is imposed. Where multiple officers are appointed, their subject-matter and territorial jurisdiction must be specified. Adjudicating officers exercise specified civil-court powers, and their proceedings are treated as judicial proceedings.

Section 45 establishes a residuary penalty for contravention of rules or regulations made under the Information Technology Act, 2000 where no separate penalty is prescribed. The contravener may be required to pay compensation to the affected person or a penalty, with either liability capped at twenty-five thousand rupees.

Where a person does not file a prescribed return or furnish required information, books or other documents within the time specified by regulations, liability may extend to a daily penalty not exceeding five thousand rupees for as long as the failure continues. Failure to maintain mandated books of account or records attracts a separate daily penalty not exceeding ten thousand rupees during the continuing default.

Section 43 imposes compensatory liability for unauthorised access to computer resources, extraction of data, introduction of contaminants or viruses, and damage to computer systems, networks, data or programmes. It also covers disruption, denial of access to authorised users, assistance in unlawful access, and fraudulent charging of services to another person's account through manipulation of computer resources. Damages by way of compensation are payable to the affected person, subject to the prescribed maximum.

Subscribers must exercise reasonable care to retain control of the private key corresponding to the public key in their Digital Signature Certificate and prevent unauthorised disclosure. A compromised private key must be promptly reported to the Certifying Authority in the prescribed manner. Liability continues until the Certifying Authority is informed of the compromise.

Acceptance of a Digital Signature Certificate is deemed where a subscriber publishes or authorises its publication, places it in a repository, or otherwise demonstrates approval. The subscriber thereby certifies to reasonable relying parties that the corresponding private key is held lawfully, representations and material information given to the Certifying Authority are true, and information in the certificate within the subscriber's knowledge is true.

A subscriber accepting a Digital Signature Certificate that lists a public key corresponding to the subscriber's private key must generate the associated key pair by applying the security procedure. This duty links certificate acceptance to secure generation of the public and private keys underlying the certificate.

Suspension or revocation of a Digital Signature Certificate requires the Certifying Authority to publish a corresponding notice in the repository identified in that certificate for such publication. Where the certificate specifies one or more repositories, the notice must be published in every repository so specified. This mandatory repository-publication requirement applies to each instance of suspension or revocation affecting the certificate.

A Digital Signature Certificate may be revoked upon the subscriber's request, death, insolvency, or cessation of existence, and where material information is false or concealed, issuance requirements were unmet, or certificate reliability is materially affected by a security compromise. Revocation requires an opportunity of being heard for the subscriber. The Certifying Authority must communicate the revocation to the subscriber.
