This question asks how a citizen can begin the process of changing the law.
Some questions about how law is made (and unmade) are clearly on topic; those concerning common law and precedent, for example. This one is more difficult because it's asking about the democratic process of effecting a change in the law, but part of me thinks that it too should be on topic, as questions about the validity of the resulting legislation will inevitably arise.
Should the example above be on topic and, if not, how do we draw the line?
