Among other conditions under which a passport can be revoked, the Passport Act 1967 allows the passport authority to revoke a passport if they deem it necessary to do so in the interests of the sovereignty and integrity of India, or friendly relations of India with any foreign country; or if the passport holder has, after the issue of the passport, been convicted by a court in India, and sentenced to imprisonment for not less than two years; or upon orders from a court during proceedings with respect to an offence allegedly carried out by the passport holder before a criminal court.
