what is the offical power of the supreme court?

Question

what is their jurisdiction as well?

Answer 1

Their basic job is to decide whether laws passed by Congress or by individual states are in conformity with the US Constitution, and as the final court of appeal, whether due process has been carried out in conformity with the Constitution.

If a law is contradicted by the Constitution, it is no longer law. If things have happened in a trial that violate someone's consitutional rights, a new trial can be ordered, or a new verdict decided, which then sets a precedent that other appeals courts must consider from that point onward.

Answer 2

The Supreme Court tries the trial as the last court of appeals. The Chief Justice of the United States who also sits on the Supreme Court has jurisdiction over all Federal appeal, circuit and district courts. There are nine Federal circuits, so each of the associate justices and the Chief Justice of the United States also oversees one of those circuits.
Because of the majority opinion written by Chief Justice John Marshall in the case of Marbury versus Madison in 1803, the Court has also taken unto itself the power to rule on the constitutionality of state and federal laws. In that opinion Chief Justice Marshall wrote that "all laws which are repugnant to the Constitution are null and void". Article III of the Constitution never gave that power to the Court, but it has gone mostly unchallenged since 1803.

Answer 3

The SC is the court of last appeals. Jurisdiction over every state case from the appellate courts.

Answer 4

Obviously they jurisdict all the way into your uterus, because there was no vote on what viable human life is, supreme court decided that all on their own- ever wonder what else they decided all on their own?!
