The cause in the case is caused by steamboat, Americans Fulton invented steamers, to the New York state legislature to apply for patent monopoly steamboat business, in order to protect the interests of the New York state legislature, legislative provisions all operating steamboat business in New York must get the permission of the Fulton, which has a great impact on other states the steamboat business development. Later, a man named Ogden who protest against such practices, but didn't get the state government, the state legislature, the state court support, but he can only buy the franchise to Fulton. However, one after another, another American, Gibbons is also very dissatisfied with this system, because of his steamboat Ogden in the area of operations, so Gibbons brought on Ogden's lawsuit, until the case to the Supreme Court of appeal America.

The main problem case involves is according to the provisions of the constitution of management America interstate trade power at the federal, state legislatures have the right legislation. As justice Marshall as the representative of the decision of the Supreme Court is the state of New York, a steamboat monopoly and federal laws to contradict, therefore invalid, thus breaking the shackles of local protectionism, opened the door for the development of the trade and other economic, also open the door for the anti-monopoly system.

Read the article, feel two:

First, Marshall identified two principles of interpretation of the Constitution: the Constitution Constitution must be understood from the text of the "natural meaning" first; specific constitutional authority should consider "bestow this power to achieve the purpose". I think as engaged in legal occupation person, should remember these sentences, the law is dead, by legal person is live, want to write the paper law vivid rise, will use the legal interpretation of the means to continue to pull into the legal provisions and cases between the fact that, if you can do that and let everybody agree, then you are a successful judicial workers.

   Second, Marshall in four cases the decisive role has been finished in this book, the final judgement to give him time to. The book said Marshall is the first person America constitutionalism, chief justice great fully deserve, is USA constitutional history, USA Supreme Court history on the top of figure, I think this evaluation is objective. However, such a law master so accurate, influence America process character with the law, was one of only a year old, on his education and his father has no culture "commoner", people marvel. His success proves that experience rather than a degree, is to become the primary conditions for great justice. His experience of contemporary justice, especially the judge group have also been inspired?
