In what federal court can the government sue?

The government has the right to sue in all federal courts and exercises this power frequently.

Explanation:

The government has the power to sue someone in particular, a firm, or a state on its own behalf to the federal court.

This right was granted so as the government could consult the court in the view of conflicts with states districts or people of importance clashing with the government over laws or other important terms where the guidance of the court may just be necessary.

This law was being used by the government as soon as 1818 when it sewed the new states to follow  the federal rules.
