The grammar was criticised during the drafting phase, extensively and repeatedly, by numerous individuals including myself. As far as I know, not one correction was made before it was submitted anyway. A body that produces legally-binding and world-altering legislation is entitled to expect a spell check.
Do I believe that calling people out on this will change anything? No, not really, especially when we're talking about an author who apparently can't tell the difference between 'rouge' and 'rogue'. Poor spellers will always exist. Doesn't mean we can't hope for a better future.
