During the Roman Republic the praetors, who were the second highest ranking officers of state, were like chiefs justices. They issued the Praetor's Edict, which stated the praetors' policy on judicial matters for their term of office (one year). Praetors endorsed much of the content of previous edicts, thus ensuring continuity. Although praetors were not legislators and could not introduce new laws, they could make amendments. These introduced needed innovations. Therefore, the development and improvement of Roman law during the Republic owed a lot to the praetors. This role ended when emperors took charge of legislation.
Jurists (legal experts) played a crucial role in the formulation legal matters and the development of Roman law. Since the praetors were politicians, not lawyers, they often submitted consulta (written questions) to jurists and their replies were often used for the compilation of their edicts. Emperors also relied on the advice of jurists for their own edicts. The emperor Justinian I commissioned two textbooks for law students in the 6th century AD. They relied heavily on the writings of some prominent jurists of the 2nd and 3rd century AD
Laws are passed by the legislature - enforced by the executive - and interpreted by the court.
The President of the United States, who currently (in 2013) is Barack Obama, has the responsiblity of carrying out the laws enacted by Congress as interpreted by the Supreme Court.
Being an attorney means knowing what the laws are and how they have been applied. You need to be able to read the laws, and the court cases where judges have interpreted the law. You will do a LOT of reading.
the supreme court
The Supreme court determines how laws that are passed by Congress are meant to be interpreted and applied. The Supreme Court also determines whether a law passed by Congress is unconstitutional or not.
In the US: The law is the same for everyone. There are no separate laws written to apply only to mentally ill individuals.
That's interpreted by the court.
the supreme court has the power to interpret the laws no matter what
The Constitution is the law of the United States. It is interpreted by the Supreme Court. Scripture is the law of God and interpreted by the Magisterium.
This amendment speaks to state militias and the right to bear arms. Added: In a recent Supreme Court ruling the right of individuals to keep and bear arms (at least at the Federal level) was how the Amendment was interpreted.
It means that laws are to be interpreted objectively, not reread by individuals and are to be applied to everyone without regard for their positions, reputations or personal relationships with others. A government of men, on the other hand, would be one that is subjective, depending on the relationship of those enforcing the laws and those against whom the laws might be enforced.
Court decisions affect how the Constitution is interpreted. Amendments are made as society continues to grow and change, and new laws need to be made, while outdated ones are changed or abolished.
