No. The key issue would be that there be a relatively short-term expiry period in order to ensure that exemption orders aren't used for purposes other than emergency circumstances. There's no magic in the number of one year, and there may be reasons that a different time period is appropriate. We also note, and it should be included in that amendment, that the minister could set a shorter time period in the order itself. That's not the required timeline; it would just be the cap on that.
