The Constitution limits the jurisdiction of federal courts to prevent them from interfering with state courts

Explanation:

The constitution is essential towards the jurisdiction of the government court  to prevents its impedance to state courts. Section two of article three of the constitution characterizes the locale of the government court as far as its extension and the cases it can deal with. This forestalls a potential impact between the state and government laws.

The constitution has been corrected after some time by congress to restrict the ward of the government court.
