Magna Carta: Main provisions still relevant

The two key points still relevant are:
  • The rule of law. In other words, the King (the executive) is subject to the law.
  • The right to due process, that is, to a fair trial.

When originally signed by King John in 1215, the Magna Carta was intended to strengthen the powers of the barons and other feudal grandees. During the confrontation between Parliament and the monarchy (1620 onwards) the Magna Carta was used to resist absolute rule.
