That would be acceptable proof. There might be some other documents as well, depending on the lists that the committee accepts. For example, a letter containing a bill, a lease or insurance addressed to the person at that address. The person may have his or her driver's licence in one place, but proof of insurance in the place where they are going to school. That would become an acceptable document, as I was saying earlier. So, there is a variety of documents that could be used to prove a person's residential address, for purposes of registration.
If you maintain this requirement for voting itself, provision would have to be made that this is also an acceptable document on the list of documents suggested to the committee.
