Those definitions didn't really clarify the use of 'any' in our situation. I think in our context the most logical understanding is that 'any citizen' means 'only citizens' because it specifically states 'citizens'. A statement such as 'any MP may propose a bill in Parliament' would hardly mean that anyone can propose a bill. If the intention of the Overhaul was to also allow non-citizens to make proposals that's fine, but that's not what is permitted at the moment.
