What does article 3 of the constitution deal with?

Article Three of the United States Constitution establishes the judicial branch of the Federal government. Under article three , the judicial branch consists of the Supreme Court of the United State's, as well as lower courts created by Congress. Article three also defines treason.

concurrent jurisdiction is the ability to exercise judicial review by different courts at the same time, within the same territory, and over the same subject matter. for instance, a domestic violence matter may be heard in either a general civil court or a family court in the same county. whichever court actually exercises its jurisdiction first will do so exclusively.
