英[prɪˈrɔgətɪv kɔ:t]美[prɪˈrɑɡətɪv kɔrt]
A prerogative court is a court through which the discretionary powers, privileges, and legal immunities reserved to the sovereign were exercised. In England in the 17th century a clash developed between these courts, representing the crown's authority, and common law courts.
