T The case of the cancellation of the \\\"legend\\\" trademark, wich had been registered under the name of sandi hakim in indonesia, was filed by wahl clipper corporation, a company based in united states, on the grounds that they are the legitimate owner of the \\\"legend\\\" trademark as an internationally well-known mark. wahl clipper corporation claimed to have filed trademark applications for \\\"legend\\\" in several countries such as vietnam, singapore, malaysia, thailand, and south korea. however, to date, these applicatons are still in process and have not yet received trademark certificates. despite this, the panel of judges granted the cancellation request on the grounds that the mark was considered a well-known trademark. based on the legal reasoning used in the decision, the trademark owned by sandi hakim was eventually cancelled. the main issue that arises is why the judge granted the lawsuit and designated the plaintiff\\\'s mark as well-known trademark, even though it was not yet registered, and whether the legal basis used was in accordance with the trademark law. this research applies a normative juridical method with a descriptive approach. the result of this research shows that the decision made by the panel of judges to declare a trademark as well-known does not align with higher regulations. this raises legal concerns because the legal reasoning is not fully in accordance with the provisions of the elucidation of article 21 paragraph (1) letter b of the law on trademark and geographical indications (trademark law), which should be based on more concrete evidence of reputation, such as a trademark certificate, rather than mere trademark applications.
