To the extent that the person was warned and later on needed to be warned again or referred again, proposed paragraph 10.4(2)(a) would limit the record of that warning to the initial proceedings where the person was warned. There are other paragraphs that would permit the use of those records, for instance, proposed paragraph 10.4(2)(b). The record could be released to a police officer for any purpose related to the administration of the case, but again, it would be limited to that to which the record relates.
If you go a little bit further, under proposed subparagraph 10.4(2)(c)(ii), the record could be used for instance in a presentencing report, but again, it would be limited in respect of the offence to which the record relates.
