In Thailand, registrars seeking to solve the problem of a mistakenly registered trade mark may call upon the solution in section 61 of the Thai Trade Mark Act, which permits the Board of Trade Marks to re-examine such marks. Based on this section, the Board conducts re-examinations on distinctiveness, dissimilarity, and morality grounds only when an authorised person, limited to either an interested person or a registrar, files a cancellation petition to the Board citing section 61. In the view of many registrars, section 61 provides a means of effectively revisiting decisions; nevertheless, the registrars, having already given their approval, rarely seek to use this solution. Recently, however, the Board rendered a decision in favour of the registrar's use of section 61 by withdrawing a registered trade mark which had been registered for more than five years.
