Clause 3

within a period of 12 months from the date of the grant of the licence, the record of the holder of the licence (as kept by the Deputy Commissioner of Police for the purposes of this section) as a driver of motor vehicles establishes that it would not be in the interests of public safety for him to continue to hold the licence, or that he is not competent to drive a motor vehicle;

the holder of the licence —

had, at any time before being granted that licence, committed an offence while driving a motor vehicle of a class or description which he was authorised to drive by virtue of another driving licence held by him at the time; and

after being granted the first-mentioned licence, is dealt with by the court or the Deputy Commissioner of Police for the offence referred to in sub-paragraph (i) in such manner as would, by virtue of any rules relating to the prescribed test of competence leading to the grant of the first-mentioned licence, have caused him to be disallowed from taking such test had he been so dealt with for that offence before he took that test; or

the Deputy Commissioner of Police becomes aware of a circumstance that would have required or permitted him to refuse to grant a driving licence to any person, had the Deputy Commissioner of Police been aware of the circumstance immediately before granting the driving licence.”.
