My last question is with respect to secondary use. You spoke to the importance of a necessity requirement for collection. Once government has collected that information.... Witnesses last week talked about different standards, so obviously in the private sector it's a consistent-use standard, with the initial consent that's been granted. In the public sector, you could have a consistent-use standard for secondary use, you could have a compatibility standard, or you could simply have a necessity and proportionality requirement for a further program.
I wonder if you could speak to rules in your jurisdictions with respect to further secondary use and what standard you think should be adopted.
