In fact, unfit people, like everyone else, have the right to vote. They have to express that desire. When it comes to the special ballot, they still have to sign the outside envelope. There's an indication of action on the part of the person voting. Obviously, signatures can be forged. No system is bulletproof.
We explored the hybrid system some years ago. We started looking into it in 2018. Technically, it's possible to do. We would have to change our systems to do it, but it would be possible. There are still challenges. To keep voters from having to buy three different sizes of envelopes to make the insertions, which is very difficult, we designed a model, a folding system, which can be a bit complex for the voter. The voter would also need to have a printer, but fewer and fewer people have printers at home.
Given the number of voters abroad, which was lower than it is now, and the complexity of all that, we didn't find this system to be a promising avenue when we looked into it at the time.
If the government wants to explore other mechanisms, if it's prepared to go further, there are more modern versions of telephone voting, if I may say so. I'm thinking of teleconferencing, where you see the person showing their ID and then being brought into a separate virtual room to vote anonymously. That wouldn't be allowed under the current legal framework, but it seems to me that it's more rooted in the future than methods such as folding, different envelopes formats and postal returns.
