(1) Where a person, by means of circulars, advertisements or otherwise, threatens a person with an action or proceeding for infringement of a geographical indication which is registered, or alleged by the first-mentioned person to be registered, or with some other like proceeding, a person aggrieved may, whether the person making the threats is or is not the registered proprietor or the authorised user of the geographical indication, bring a suit against the first-mentioned person and may obtain a declaration to the effect that the threats are unjustifiable, and an injunction against the continuance of the threats and may recover such damages (if any) as he has sustained, unless the first-mentioned person satisfies the court that the geographical indication is registered and that the acts in respect of which the proceedings were threatened, constitute, or, if done, would constitute, an infringement of the geographical indication.
(2) The last preceding sub-section does not apply if the registered proprietor of the geographical indication or an authorised user thereof with due diligence commences and prosecutes an action against the person threatened for infringement of the geographical indication.
(3) Nothing in this section shall render a legal practitioner or a registered geographical indications agent liable to an action under this section in respect of an act done by him in his professional capacity on behalf of a client.
(4) A suit under sub-section (1) shall not be instituted in any court inferior to a district court.
