In constitutional law, the bill of rights lists the rights that are guaranteed to all citizens. In most countries if citizens feel that their rights have been contravened by an act of the government they can bring a case before the constitutional court, arguing that a specific, listed right has been disregarded. Alternatively, the bill of rights could be replaced by a single, undefined ""right to justice"". Under this new system, if citizens felt that any right had been contravened by an act of the government, they could bring a case before the court arguing that their right to justice had been disregarded. They would have to show that the specific issue they are bringing to the court falls within the scope of the right to justice, which would be decided by the constitutional court based on argument and legal precedent.
