'Our ancestors were not daft, they knew there could be a problem one day if the crown became unjust, or turned into some sort of dictatorship, or parliament was acting against the people, or was full of corruption, or was not allowing the crown to keep its oath.

So in article 61 of the Magna Carta it was written that if this ever happened you could petition the crown to sort out the crowns problem (or parliaments if it was them), the crown had 40 days to fix it or dissolve parliament.
If in the 40 days nothing was fixed the petitioner could go into rebellion against the crown and parliament lawfully until the problem was resolved.

Because this was lawful and the petitioner had a right to do it he would go into “lawful rebellion”, he would no longer have allegiance to the crown or parliament because they had become corrupt etc, he would be a hindrance and a rebel, and fight to end the corruption or injustice within the system, it was law that he could do this, and he was actually obeying the law by doing it, because it is the peoples duty to fight corruption and uphold the law'
