the report, complaint or allegation indicates that the conduct of the officer concerned is of a serious nature and that an imprisonable offence may have been committed by the officer concerned; and

the conduct is such that, were the case to be referred to a hearing under regulation 11 and the tribunal or officers conducting that hearing were to find that the conduct failed to meet the appropriate standard, they would in the opinion of the appropriate officer or appropriate authority be likely to impose the sanction specified in regulation 35(2)(a) or (4)(a) (dismissal from the force); and

the report, complaint or allegation is supported by written statements, documents or other material which is, in the opinion of the appropriate officer or appropriate authority, sufficient without further evidence to establish on the balance of probabilities that the conduct of the officer concerned did not meet the appropriate standard; and

the appropriate officer or appropriate authority is of the opinion that it is in the public interest for the officer concerned to cease to be a member of a police force, or to be a special constable, without delay.
