22 On the other hand a "serious conviction" within the meaning of the Act is one in respect of which imprisonment for more than a year or for an indeterminate period, or a fine of $15,000 or more, is imposed (s 9). Under s 6 of the Act, in that event, after a minimum period of 10 years following the conviction, the applicant may apply to a District Court Judge for an order declaring that the conviction is spent. In that case the power of the court is discretionary in character. The matters enumerated in s 6(4) as being those to which the Judge shall have regard in exercising the discretion, are concerned with the seriousness of the offence, its nature, the circumstances surrounding its commission, the length of time since the conviction was incurred, the length and kind of sentence imposed - all matters concerned with the seriousness of the offence. In addition, the circumstances of the applicant are to be considered, both as at the time of the commission of the offence and at the time of the application.
