hope this helps sorry if its a little long

Answer 2

The king could continue to rule but must keep to the established laws and customs of the land.  It also states that no freeman (i.e. a person who was not a serf) will be imprisoned or punished without first going through the proper legal system. In future years the word “freeman” was replaced by “no one” to include everybody.  

I don't think this is the answer but sorry if it isn't
